to all the people complaining-ask yourself why your discus dont look like these massive water changes are so good its untrue and these have developed a system where everything is matched so its easy drain it out put fresh in...just because it aint going in one bucket at a time this is fish farming on a large scale what do you expect ?? it might look a bit stressful but as we all know with discus if it was a problem they would let you know they would not be 12" + and healthy
I need to build a drainage system like that in my own fishroom...Kinda hard to do in a finished basement w/out the wife getting resentful of my fishkeeping efforts, though :P 100% water changes are very common in most professional breeding farm setups...though usually the water is drawn off more gradually through a central system, where the new water is introduced and exchanged with the old water via the central sump reservoir, as opposed to being piped directly into the tanks...
@zirchsoft like i said, i prefer to learn things through experience. If my discus is fine with what i'm doing, why would i care what someone else says? actually it is a 10 gallon tank with 2x 2inch discus that i'm growing out. It is not water volume that matter but the quality of it when it comes to growing out fish. I do have a filter on it, but with 4-6 feeding per day of high protein food, the tank water gets foul fast. Thats why we need big water changes. so, how many discus do you keep?
@zirchsoft like i said, i dont always go by site for what i do, and i dont look from backup from them either. As far my discus tank goes, I change 90% water everyday. The water i add is treated with a de-chlorinizer and set to the right temperature. The water out of my tap read around 7.6, and since i change everyday, i know there wont be a sudden change.
@zirchsoft what i'm saying is, You can have a 1 discus in a 180 gallon and if you dont keep the water quality up, the discus is going to be stunt. you can have 1 discus in a 20g all its life, do daily water changes and not have it stunted.
@zirchsoft Well, thats my point dude. you asked the other person if they had ever seen this happen in the nature and thus my reply. By the way, amazon is the place with ALOT of rainfall, rain doesnt always have the right ph or dh. I'm not sure if there is chlorine in the water they are using. Dont think in too much, if the discus has grow to such large size without any quality issue, why worry too much? "If it aint broken, dont fix it"
@zirchsoft what makes you think the water in the tank and new water has a temp or ph difference? No one replaces warm water with cold water during WCs. btw, if you didnt know, in certain places in the amazon the ph changes drastically within 100 feet.
I think it's a little ridiculous that people are saying they don't know what they are doing. Obviously, this is an already established farm, where they look like they've done this many times, and have probably had alright results before or they would've stopped doing it. As for whether this is unjustifiably stressing the fish out is another argument altogether
I'm sure this is accepted practice in certain fish farms, but to me, it seems very inapropriate. I've lowered water levels to the point that Discus are on their sides, but it isn't necessary to go that far, as it stresses the fish. Then to direct a blasting jet of high pressure water at the tank floor, while the fish are on their sides, with no way of swimming away from the jet blast of water, that's just plain cruel. To add insult to injury, the workers are all smoking away while the water is mixing in the air/smoke mixture into the tanks....I feel really sorry for those fish, seems like a puppy-mill style mentality to me; the fish are just slabs of meat to be sold for profit, and the end justifies the means.....sad.
@csh482 yer i dunno such a rapid change of water chemistry is very stressful, And ur spot on about being stressful in dirty water but these tanks should all be cycled and regular partial water changes should be maintained.
It's only stressful with the way the water enters the tank. dual entry on the side would provide the same aeration as aggressive coagulation like pressurizing water into tank like that. But either way they will live. fish are hardy. idk about discus tho. last I heard they fragile
@zirchsoft I didnt say rain affects the whole amazon. Rain can change ph at the top colum of the river since well, it is the part where rain comes in contact with the river. rapid water changes like that is happening in the. if the water changed has the same ph and temperature, it is just like a river flowing across a fish.
I guess this video proves that Discus are not as difficult to keep as many think, if they can handle the stress of laying on their side with just enough water to cover them for a minute then they can handle a routine water change by someone who actually cares about them. That water was a nasty yellow to begin with in the first tank, that shows they don't do normal water changes enough.
Probably water is dirty because they overfeed the fish, and honestly, I think they have that quick-water-change system because they do that several times a day.
I don't understand how this video has so much hate. The fish are fat,healthy, and colorful. The water change didn't hurt any of them either. Did you expect them to siphon each of those tanks?
i agree with you .. But if i don't have a farm like the one in the video and just have a well planted aquarium and i have some discus in it beside many kinds of small fish ..so how can i do this and change 75% of water daily ..is that will not has any effect on plants ? and also the other fish !??
@zirchsoft btw, did you know the habitat where discus is found is shallow streams of the amazon where rain water replaces most of the water everyday? Discus cant thrive in a tank polluted with nitrites and ammonia. Discus have very small stomachs and need to be feed portions many time a day for them to grow well. This feeding schedule fouls the water and cant be kept under control with just filtration. have you ever seen a discus that has been kept in tanks with no WC and reach 6+inches?
@zaracki92 again, i will ask u, even if the water is replaced by rain..where is your basis that the rain over there reaches 7 - 7.4 and affects the ph of the water of the amazon? where???
@rglibra1015 Is Asia, the ambient air temp averages 30-35C year round so they don't need heaters and the water comes out of the cold tap at 30C......I know this because I leave in Asia and also keep Discus. So no temp change during water changes :)
I don't know why this video is so criticized. Fish experience even bigger stressful moments when they arrive to the pet stores or when they are bought on the internet.
@zirchsoft againj i will tell you, i wasnt talking about the rain in amazon, i meant rain water in general. you said rainwater is used to reduce ph. not always.
One final thought...all that high-pressure water churning up the water in the tanks is super-saturating the water with oxygen, which is hugely beneficial for the fish.
@zaracki92 you can do water complete change. but is it good practice? is it healthy and good for the fishes on the long run? no one, will tell u, that it is good (i speak of experienced and professional aquaristic ppl). its like "u can smoke" but it is not healthy. again i will ask u, what site teaches that complete water change is good. show me 1 site advising it.
@zaracki92 i never said that the rain lowers the PH in the amazon. what I am simply telling u, and i hope this gets into your mind, is that since rain in the amazon is never high PH, it does not affect very much the amazon river that has also low ph. there is balance in that environment. no where in my statement did i say that the water in the amazon has low PH bec. of the rain. the rain works in "harmony". not against it.
@zirchsoft maybe you should learn more about amazon. It has much larger water volume than lake tanganyika. i constrain myself to discus because 1. this is a discus video 2. Frequent water changes and constant feeding isn't practiced with other fish. It is done to grow quality discus.
I agree that 50% would of been fine, sure discus like there fresh water as if it where in nature, but just leave enough for them to swim in at least and dont blast the heck out of them with the incoming water flow, thats not cool, but beautiful looking Discus!
Discus is a very sensitive type of fish. Any perceived threat or disturbance may prove to be deleterious to its development and well-being. The way that the fish were handled in this video will not kill fish but it will stress the fish severely. Good day.
Wow could imagine the fatalities they get from the sheer stress of their water changes O_O and to top it all off, some sod was lighting a ciggie right next to the tanks...
@1Filmproducer Obviously the floor will be angled into one or multiple drains so it all drains away, so less pipes and no limits on the number of tanks or the need to put a new drain in every time a new set of tanks are added, is that not obvious?
@zaracki92 can u compare the water of the rivers / lakes to the water from ur aquarium and fountain? in nature there is a every second of thousands of liters of water changed, but with the exception with NO rapid PH change,no rapid DH change.also, take into consideration d nitrate/nitrit d is within 1 aquarium,more also, dont 4get d chlorine dat is in our waters. another thing to think of is the humidity, and d water that flows thru metal pipes. do not compare nature's way of filtering water.
I think this is good way to rise discus, I do the same thing, it need cheap water with good quality, bio filter is get more expensive and we dont have much space for that bio filter. imagine when you have 300 aquarium for one or two employee, imagine when there is no employee if holiday time, i do everything my self.
Can i know what are the effects of this on discus fishes ? As I heared it is good for growth of the fish as it remove ammonia and other harmful substances
How is this bad for the fish?? An almost 100% water change is what you need in an envrionment where the fish are crowded, like a commercial farm. The techniques used are not harmful at all, just very different from hobbyists with one of two tanks at home. That knowledge comes from 8 years running a ornamental fish business. fish are pretty resistant to these things.
the assumption is that the water is from well water, or from the river, or is from a tap that does not have chemicals or chlorine gas. For instance, I think in Norway they have such pristine water quality they dont need any water conditioners for their tanks.
This is how to grow large, healthy discus-- never let waste products build up in their water. They aren't being stressed at all. The new water is the same temperature, pH, hardness, etc., as the old water. Dirty water is what stresses discus. All good fish breeders make very large, very frequent water changes. It's time to retire the old myth that large water changes are bad for fish. I'd love to be able to do a complete water change on dozens of large tanks in under ten minutes.
I disagree about the stress part, those spray bars are shooting water too hard right at the fish when the water gets really low. You can see it gets so low the fish are actually on their sides and getting just punished by the current the whole time. Sure its not gonna hurt them per say unless they get shot by the jet of water directly, but still. Why ? You can make that refill so much easier on the fish by just diverting the spray bars onto the glass higher up and not draining the tanks so low before you refill.
pac6010 Spray bars would be a good idea. Still, the fish can move out of the way of that jet if it's bothering them. And they aren't on their sides for more than a minute or two (and never completely out of the water).
Gary Cooper Did you not see the same video I did? They was on their side with that jet hitting them when the water was very low, they moved out of the way with the help of that jet throwing them out the way. Use your eyes. This is very fast and healthy water going in but also VERY stressful on the fish in the tanks
Don't remember exactly what I wrote but pretty sure I never said this method don't work, all I said it puts them under hell of a lot of stress and that those jets honestly are too powerful to be pointed at the bottom of the tank if they are doing 100% W/C's. It does work I just believe they could be kinder to the fish by not blasting them with that powerful jet of water directly. direct it at the wall of the tank or something
EVERYBODY!!! look how big and beatiful their fish are. I'm sure they know what they're doing.!! For the mean time, why don't you do a water change on your filthy aquarium.
@zaracki92 point is this: water in amazon is low ph. rainy place, low ph water. have u ever measured the PH level of the water of amazon? its a rainforest dude. hard water places often dont get as much rain as amazon, like for example tanganyika, victoria or malawi. sometimes they get rain but its also a big lake. amazon and its balance in water and nature is already built. that is the point. u can never tell me, that the ph of the rain of amazon is above normal ph level.
@SMGene06 AMEN!! Would LOVE to have this system for my own tanks, the more often and greater the water changes, the faster and healthier the fish grow!
Holy cow! Doesn't water with that much PRESSURE hurt those poor delicate, high stress, and ridiculously EXPENSIVE fish??!! I know that much water pressure would really hurt MY skin... My goodness
@zaracki92 you should also never compare a river or lake to aquarium "complete water change" bec. the water (even if it filters) does filtering in a natural way. and if PH/GH changes, it never happens in a rapid manner. more also, water from the river is never the same like water from your fountain. the bacteria is constantly there, the temperature does NEVER change rapidly. the water at one place of the river and the water 100 feet away of the river will taste the same, and is the same.
That has to be one of most stressful water changes i have ever seen,loads of time for the fish to acclimate to the PH and temp. diff. that is a prime example of people that dont give a flying fuck about the animals in there care.
wow thats crazy!!!!!!! im assuming you guys have pretty good business in order to pay the bill stated bellow. on the other hand is the wood treated? i see so much water running and it seem to run under other stands twice daily this must affect the wood some how. on a side note, those are some nice fish!!
its not to much, clear water makes them grow faster and bigger. the discus here get 2x a week 50%water change and 1x a 80%. i do agree that is verry stressfull fo the fish doing it like this.
the only reason they pump water that strong to aerate the water since all their water is coming from storage tanks, however if they did not mind the cost of adding aeration systems into their water storage tanks than they will not need to pump water that strong. hence fish are less stressful!
@zaracki92 and again, back to my first question to u, what about GH? what about sudden water temperature change? what about chlorine? humidity? and lastly i ask you, by complete water change, what happens to all the impt. bacteria in the previous water that helps strengthen the immunity of the fish? isnt that all affected when doing complete water change? YES. do these happen in the Amazon river? NO. so, bringing up your comparisons in the first place is already invalid. do more research pls.
fish get used to what not. if they got used to the aquarium.... a sprayer would be a lot easier people. what makes me curios is what kind of water is the one they're using to fill the tanks!!!
not that i agree with what they weredoing but lets b honest the fish were fine they were still completely submerged and also had fresh water flowing in and the water level was up in 1 minute
