Hello everyone. Welcome back! I’m very glad to have seen my channel reach three thousand subscribers this month. I want to thank all of you who have watched and subscribed to my channel. You have no idea how much that means to me. I can’t wait to make more satisfactory and relevant contents for you all. Some audience have left messages in the comment section but were banned by Google algorithm. Although I wasn’t able to reply to the comments, I’d like to let you know that I have noted down your questions and will answer them in my future updates. Today I want to talk about the reef tank chemistry that lies in the very core of reef keeping. If your fish or corals are in a sub-optimal health condition, instead of treating the fish or corals, you treat the water. This is, in my opinion, a very profound message that is not only applied to reef keeping, but also to our everyday work and life. The number one enemy that is holding you back from success is your surroundings that you have to be aware of. It’s virtually impossible to change your lives without changing the environment. So what water parameters are optimal? Different aquarists have different answers due to various focuses of the niche specimens they intend to culture. But there are a few fundamental chemistry principles that I believe most reefers would agree on.

The water clarity and colouration of your corals is amazing, a mixed reef in my opinion is the hardest to maintain and yet you manage to achieve this. Your reef tank tells me that you know what your doing, the only gripe I have is that you don’t push out enough videos to feed my appetite and keep me waiting for the next one 😅 I’d like to see more about the equipment you use if thats possible. 🙇‍♂️

Your presentations are fantastic, addressing the science and practical care of reef care. I'm just starting to get back into aquarium care, which was of huge interest to me in my early 20's when reef care only occured in a few public aquariums (not the trade). Over the past 30 years, my interests had shifted to aviculture where I worked professionally at a zoological park, but I see a lot of similarities to your approach to husbandry. Now that I am retired, it is really exciting to see how far reef care has come, and your approach is very unique to what I find on RU-vid. Your level of compasion and care for the husbandry of these delicate and beautiful animals is fantastic, unique among the 'reefers' I see out there, and inspiring. I would very much like to see you post more videos. Perhaps you can show if/how your methods to create your reef tank can be recreated from start to finish. Thank you.

Kits I use that I really like. Temp: InkbirdSmart controller with Apex probe/controller for redundancy. Also use Hanna temp probe to confirm and calibrate. Alk: Hanna HI772 Phosphate: Hanna HI774 I really like the Hannas for these test since once you’ve done the initial test you can take one of the extra vials and fill it with tank water and then run multiple test for both to get an average without having to use any more reagent. Calcium and Mag: RedSea Just easy and actuate I think and you can buy just the reagent when needed. Nitrate: Salifert and API. I use both to cross ref since they are so easy and take almost no time. They always show similar readings which is nice for confirmation. Tip - On the Salifert nitrate if you look top down reading = x1 reading side view of vial = x0.1 Salinity: Milwaukee and Tropic Marin glass (bobber/buoy style)hydrometer. The Hydrometer is a little difficult to use in that you need to turn off ALL flow and is a little hard to read through my eurobracing. It’s right in the line of sight of the protruding part of the hydrometer that shows the value/readings. They do end up being about .001 - .0005 (ex: 1.025-1.0255) diff from each other. So not to bad.

@zzyz
@zzyz 3 года назад
Thank you so much for the sub! I wish I could be a photographer, but I keep learning. To stabilize your PH, you have to stabilize alkalinity within 0.1 dKH fluctuation by dosing KH every 3 hours. Given the same level of aeration and same level of KH, PH will be more or less the same. I'll talk about dosing in my future episodes.
@markgresin6335
@markgresin6335 3 года назад
@@zzyz I just tried what you describe above but dosing KH (buffer) and even though it does raise my dkh, it does not seem to raise PH nearly as much as dosing Kalkwasser - barely a blip on the (apex) graph. If I bring my dkh up to 9 or close to 10, my PH is still around 8.0. And then I add the KW which boosts my PH right up there but it falls rapidly. I will buy a dosing pump once I know for sure what I will end up dosing. This has been a puzzle for me. Thanks for the info.

Thank you Chris. Yes, that's the cylindrical algae reactor, where I cultivate micro algae. Macros do not grow well in the reactor. They prefer breeder boxes that receive led light with proper daily schedules. You don't have to seed the reactor, though. Algae of suitable types would grow automatically therein. I may not dedicate an episode to the reactor itself, but in case you have any question, please feel free to let me know. I'll try my best to answer them.
@MercedesAMGsRULE
@MercedesAMGsRULE 2 года назад
I have recently found that using the method that you're using (the same as mine) my KH measures almost 0.8-1.0 kH higher than it actually is. I found that then I read 8.6 kH on my salifert test kit, by making sure the pink/orange colour didnt change any more but at my local fish sore and using a Triton ICP NDOCs test, my results kept coming back at 7.8 and 7.6 kH. This means when I was testing at 8 it was actually 7.2 which was too low and probably causing swings. Also I would still occasionally test PO4 as this can unexpectedly creep up sometimes and be harmful.
@zzyz
@zzyz 2 года назад
Thank you for sharing your experience with us. I've cross checked with Vastocean kits and the results read alike though. Stability is more important than the exact level of KH. We can bear with that as long as it is kept stable.

I want it to be either 5-6 feet long with 16 inches as the width and around 12-16 inches as the height, or I want it to be something like a 4 foot by 4 foot by 1-foot square tank. I want to build it using glass sheets from a hardware store. However, I am not sure how thick my glass should be for this project. Do you have any suggestions as to how thick the glass should be? Ultimately, I want this tank to be a shallow tank with a tang or two as the main fish. Thank you!

Thank you very much Phu! I've had this carnation tree for about one and a half months. It usually opens late in afternoon and closes early in the dawn. I think the reason NPS corals are said to be hard to keep is because of insufficient feeding due to non-photosynthetic nature.

@@black-kryptic8539 My pleasure. Never put them in together. Most of them may panic and die. Put them in one by one, acclimating each for a week. Let them see their tank mates and get acquainted beforehand. Do not force them out of the breeder box. Let them choose to leave or stay. Once they choose to get into the main tank by themselves, they are likely confident enough to adapt to the more challenging environment. Chromis is not territorial and royal gramma is a bit shy. They may show occasional aggression but in general they are peaceful species.

Thank you! I left flow on when I film. Nems, clove polyps, tube worms, etc. don't like strong flow, while SPS, leathers, star polyps, etc. are in favor of decent flow. So I put the former in places of low flow and the latter in places of high flow. I have two powerheads with the flow directed towards the water surface. If you have an SPS dominant tank, flow is a good thing as long as it is not directed towards the coral head-on.

Roger another great video, I have a question about dosing, currently my Alk is 8.3 and Ca 420 and Mg 1320. If I use the calculator available to raise the three parameters, how much do I need to maintain those parameters to keep them on target. I don't have a controller like an Apex. This will be dosed manually
@zzyz
@zzyz 3 года назад
Hi G, thank you so much! Your parameters look great already. If you want to raise them to higher targets, simply add 1/4 of your daily dosing a few times over the span of several days until the parameters reach your desired levels. The maintenance dosing amount at higher targets would be more or less the same as your current consumptions.

Is that a rainbow anemone. Do you have any problems with your sps corals? Like dying due to the anemone which leaves cells in the tank?
@zzyz
@zzyz 3 года назад
Yes, that's a rainbow anemone of Australian origin. Certain SPS corals will burn tissues if Anemones are in close contact with them, while others are more aggressive that will deter anemones from encroaching. Nonetheless I don't find any adverse effect to put them in the same tank together.

what are your thoughts about the digital testers especially for alk that's what i plan to get i want to get as many digital testers as i can coz i can't tell the difference in color for shit i saw the color change like 5 drops before you stopped in all testing i like the testers you showed that have different colors the tester i have rn is all shades of yellowish gray i can't read those properly at all i plan on getting the hanna salinity tester and alk tester digital and any other i can find.
@zzyz
@zzyz 3 года назад
I haven't personally tried a digital tester yet. As both have existed on the market for quite a long time, I guess the digital have some tradeoffs for their convenience, such as accuracy and calibration, should the efficient market hypothesis hold. If you give them a try, please kindly share with us your experience with the digital and we'll appreciate that!

@zzyz
@zzyz 3 года назад
Yes, may sting nearby acroporas. Some aggressive acros are less affected while others see tissue fading (but not fatal). So I use quite a few branching live rocks around anemones to keep them from encroaching on nearby corals and constantly frag them when they grow too big.

My alk is 10.8 dhk. Is that alright for a mixed tank? How can I lower that level?
@zzyz
@zzyz 3 года назад
It's ok if maintained stable. But there are two things I'd like to bring to your attention for a KH near 11. First, SPS polyp extension may not look as good in a high KH environment as in a low KH environment. Second, acclimation of corals especially SPS will be more time consuming if all your LFS maintain KH at much lower levels. When you lower KH, simply reduce your daily dosing volume. In my case, KH level would go down 0.5 dKH if I stop dosing for one day. 0.5 is considered a moderate shock. You may consider lowering your level by 0.2 dKH each day for 10 days in a row.

Hi Roger, I’ve been running an algae reactor with sea lettuce for a month now, but the algae is getting transparent, do you dose any iron or other supplement for algae growth? If só, which one and how often? Thank you!
@zzyz
@zzyz 3 года назад
Hi Marcelo, some algae types may not adapt to the nutrient / reactor environment. Even sea lettuce, there're tens of hundreds of species. I would suggest you let the algae compete by themselves and the most competitive species will proliferate. I dose trace elements every other day, including iron, but I don't do it specifically for culturing algae. The most likely reason why the lettuce faded away is either due to the lack of nutrients or being out-competed by other species.
@marcelohormeyll
@marcelohormeyll 3 года назад
@@zzyz thanks for your reply, I’m facing a hair algae problem in my display tank, the only algae species that grows is the HA and it definitely prefers the display tank. The algae reactor uses that pink/blue led strips. My intention was to introduce a macro algae to starve it but actually the opposite seems to be happening. I’m afraid to use other algaes that can become sexual like caulerpa.
@zzyz
@zzyz 3 года назад
@@marcelohormeyll GHA is a nightmare. I can relate. A combination of low nutrients, sea urchins, lawn mower blenny and rabbit fish may help you combat them, but it takes time and by no means easy. Caulerpa will go sexual when nutrients are depleted and pollute the entire tank. Let the algae reactor run without adding any seeds. Algae of suitable types will thrive in the end.
