@@matlarsweta its very interesting to say the least! What all is in there? I saw some crabs and a fish or two I believe? Do you ever have to worry about the fish beaching themselves in some kind of muddy tide pool? Are the plants real?
@@MrHellsChaos Yepp. Thats exactly how its running and its pretty simple system really. The lower tide drains slower, something you will see in nature too. water always goes out slower than in during hight tide.
@@adamshepherd6810 Yupp, thats right. When the pump is running it pushes up more water than the short pipe can drain. At the high tide mark, there is a third overflow drain. 6 hours later when the pump stops, the water slowly drains through the lowest pipe back down again.
Currently no mudskippers in the setup. What you’re saying are probably crabs, snails or guppies. We are still unable to get mudskippers in New Zealand Due to Covid.
Oh wow, I'm gonna save this idea for a project I was planning with freshwater pom poms crabs and sparkling gourami to see if I can encourage any breeding behavior... can I ask what species you used other than mudskippers? Also, I would love it if you made a quick tour of the set-up, even if it was just a quick peak in your cabinet at your holding tank and pump set-up... this is wonderful! I was wondering how to smoothly transition a 'slow river/rice paddy' set-up... this gives me ideas already.
Great that you are getting some cool ideas. Im sure a rice tank would be just as exciting and you could actually grow rice plants in it too. Currently it has mud crabs, ghost shrimps and bumble bee gobies. Still awaiting import of mudskippers to NZ where we are located. I will make a video on pump and sump set up, so stay tuned.
Thanks. Yeah. These are Avicennia marina, ssp marina They grow really well, and does response ok to some trimmimg too. (Well until the last trim I did and did a bit of extra hard, and they are slower to bounce back from that.)
This is genius and amazing! How often do you change the water? I would suspect you only change the water from the main water reservoir thus everytime the tide comes in, they have fresh clean water rather than old dirty water?
As this is quite warm water 28 c, it evaporates quickly, so constant top up is needed ontop of the fortnightly water change. Salt dont evaporate though. So the top up is just fresh water. The water change water is made up brackish.
Its a pretty easy and basic system. A sump underneath with a pump on a timer. A three pipes with some valves connected between the tanks. One for low tide, one for the inflow pump and one for the drain of the high tide. When the pump is on it floods the tank, as it raise the water and don’t fully drain as fast in the low tide until it reaches the main high tide point. When the pump is off 6 hours later it drains, almost as fast as it filled up.
with the timelapse you can really see how the creatures inside (especially crabs) tend to move around and around, back and forth doing almost always the same path. I just wonder how much this can be frustrating for a living creature...at the end of the day, they are just made for open space and freedom, not for cages. Just my thoughts
Do you do anything to the water that's removed during low tide? In the real world the water coming back in would have been mixed with different brackish/saltwater and have different organics and nutrients.
The upkeep for this must be ridiculous. Having to pump and drain all that water regularly. SALT water at that. Is the water being cycled or filtered constantly as well? Or do you have to dump out the old salt water and refill the tank with a fresh batch each time?
ive wanted to do something like this for quite some time and the only way ive been able to make it work is with 2 pumps on timers that click every 8 hours for about 60min each how did u do it?
@matlars21 ve need a new update on this sick tank built. Measurements: tank and sump, sediment level, water level, high and low tide Equipment: pumps, light, heater, dosing species: fish, critters, plants concepts and ideas behind the tank: biotope if anny and decisionmaking Considering doing one myself using a 90*45*90 exo terra terrarium, but thinking it might be to shallow for a tidal setup.
Thanks. Will do an update on this very soon as it suddenly became quite the popular post. So stay tuned and thanks for your patience :) Great that you are considering something similar.
They grown really well. These are Avicennia marina, ssp marina. They grow really well, and does response ok to some trimmimg too. (Well until the last trim I did and did a bit of extra hard, and they are slower to bounce back from that.) Avicennia seem sto be easier to grow than Rhizophora
But actually I was wondering the same thing, I'm doing a red claw crab tank and I want to make it as close to a mangrove habitat as possible. I wanna find the wood, especially since it's the closest I've seen to resemble the roots of a mangrove tree.
Its pretty cool, but a simple system. A sump, pump on timer, pipes connecting to top tank. Deep mud layer with microrganisms to act as a bio filter and mangroves. A bit of work, but a simple and rewarding system. Ill try to make an updated video soon :)
Its always interesting to see how they utilize the flooded land areas for feeding during high tide and seeem to have their territories which they claim back as soon as the water raises. A deep mud layer also allows burrowing for the crabs and mudskippers( still awaiting the import of mudskippers here). A normal aquarium, these guys would miss out on acting on these natural behaviors and therefore you loose out on important enrichment, welfare and best practice husbandry.
Would love to see which way you achieved the slow raising and lowing of water level , are you filtering the water when it goes out of tank then. Pushing in cleaned water once it reaches minimum or delayed time at lowest/highest then rasing/lowering
Thanks. I will try to make an updated video soon and explain this a bit more. But its all a pump connected to a timer, pushing water up. the low tide drainage pipe gets flooded and does not drain as quickly as the water goes in, and therefore it will reach a high tide point and drain there/. As the timer and pump stops, water starts draining to the lower point. In nature. tide always goes out slower than what it comes in at during high tide. The high tide drains through a filter sock, there is internal filter pump too. However these are just extra additions. in a mangrove set up, you would not actually need a filter as a deep mud layer with microorganisms and bacteria acts as a bio filter. SO its more natural. Water is only muddy and low visual when the inhabitants stir it up during feeding and other activities.
Thanks. This kind of habitat set up would work great for fiddler crabs and red claws, which I used to keep in set ups like this living overseas. However, now Im currently keep a native mud crab from NZ. They are great to help with algae control and eating any dead stuff or left overs. No other crabs are on the market here, sadly.
@@matlarsweta thanks for your reply. i know that problem. here in germany you can buy some species but not all im interested in. i am breeding geosesarma 'black leg' and also keep a tuerkayana magnum (discoplax magna) and some mrtasesarma obesum sp. emerald. but hell... i want some fiddlercrabs in a mangrove tank. but its so hard to get them here...
As a mangrove set up and using mud, filtration can be tricky. In this case this is a bio active set up. A deep mud layer with living microrganisms and bacteria acts as a filter. any dead stuff gets eaten and disappears. nutrients left over is taken up by mangroves.. We do run a pump with filter and a filter sock for the overflow high tide in the sump for just stirred up mud sediments/ More coming on new video soon :) stay tuned. How did you go with your exo terra ideas?
The set up has Glass shrimps (Palaemon affinis), tunneling mud crabs (Helice crassa), malaysian trumpet snails (Melanoides tuberculata) and mud snails (Potamopyrgus estuarinus). The video had guppies as a trial sp but is now currently the tank is inhabited by bumblebee gobies (Brachygobius). Still waiting for mudskippers, which the set up is built for.. The plants are Nz Mangroves (Avicennia marina var. resinifera.)
