Preparing for Sulawesi Cardinal Tank
I'm looking to get some Sulawesi cardinals in the near future, and I want to make sure I have my bases covered before I attempt to keep them. I have a 55 gallon with fluorite in it that has been used for a few months with goldfish and plants in it to build algae and maintain the cycle.

My water parameters out of the tap are ph 7.4, kh 8, gh 12, nitrate 0. I plan on using RO water and adding the necessary ingredients to bring it in line with what cardinals need. I've read different reports but from what I understand, cardinals need 8-8.2 ph, temp 82+, kh 6-8, gh ? , TDS anywhere from 200-400 depending on the source.

Temperature I can control. GH I can add via Bee Mineral GH+. I use this to increase my tiger tank from RO to gh 6, TDS 120. I figure I can add some baking soda to increase kH. I have some aquarium ferts, including MgSO4 which I think I could use to increase TDS if necessary.

So how do I maintain pH? Can I add a thin layer of aragonite sand on top of my base? Will that buffer it enough? I've read that using coral jumps your TDS up to around 300, I can't tell if this is ok or not. And where do I get coral?

Hopefully you guys can help me out. Keep on shrimpin on.

I use crushed coral (get from any pet store) in a filter bag in the canister filter for my cardinal tank. There's another product by the same company that makes that Bee Mineral GH+, it's called salty shrimp sulawesi 8 or something like that, i'd use that to condition your RO water, it'll raise the GH, KH and pH to the exact level (or so the package claims, hah)

oh yeah, and please take the goldfish out before putting your cardinals in the aquarium!

and let your aquarium re-cycle once you change the pH and temperature, that might shock some of the beneficial bacteria into a mini cycle.

I checked a shrimp product site I use and they had two sulawesi products, one which brought the ph to 7.5 and one which brought it to 8.5. It claims cardinals will do well in either, but I would guess the 8.5 is better?

Yeah the 8.5 is better if you're getting Cardinal from someone keeping theirs at 8.5

How do you keep yours, for reference? I'll probably be getting in touch with you when I go ahead and buy some.

Mine are above 8 pH, I use coral in the filter and I use the Sulawesi 8.5
