Ideal Water Parameters for CRS?

[Ankit]

I have my tank and equipment all running now and am following a similar water change schedule as it was posted in the fastest tank cyle with ADA aquasoil. (shrimpnow.com/forums/showthread.php?t=565)

Here are what I've gathered as ideal parameters:
Temperature: 22-23C (71F - 74F)
pH: Slightly acidic, therefore definitely below 7.0; 6.6-6.8 ideal?
Nitrates - 5 ppm or less
Ammonia & Nitrites 0 obviously

Does the kH (hardness) matter much?

Please comment on these numbers, I want to bring my tank to as close to an ideal situation as possible. In my situation, temperature is not an issue because this will be in a basement where the room's temperature will be a few degrees lower than in the tank and heating it is easier than keeping it cool.

I never measure KH, unless PH goes down really quickly.

In my opinion KH doesn't have much effect on CRS.

Your numbers look good Your water should be clean, soft, slightly acidic and cool!

Thks.

I use aquaclay on my tanks. Its good because its puffy inside so the bacteria can live in it and best to have atleast 3-4inch thick gravel.
