Discus take a wide variety of Ph levels. But like somebody else said you have to maintain that level. Wild caught discus need lower ph, but tank raised discus should be fine with regular tap water. I think what everybody is thinking about when people say 'they need lower ph' is because of wild discus and the fact that lower ph increases hatch rate. Its still possible to get a good hatch rate in higher ph but i heard that higher ph can cause a harder shell for the fry to get out of, causing a longer hatching process...
can hard pH kill discus?

Higher pH levels have several issues when breeding. Biggest one is that the males sperm is not as active at higher pH levels...meaning not as many will be fertilized. They only have so long before the micropyle is able to stay open. If the sperm arent active enough to find it before it closes, the egg dies. Now once the eggs are fertilized and hardened, they can be placed into straight tap water and hatched that way no problem. Higher pH also means more bacterial/fungal activity in the water which can have an effect on the hatch out rate (even if fertilized).

Hello all! I'm a regular over at AC, but since my comp. won't let me log on, I thought I'd try MFK! This thread is interesting, b/c I'vepondered the same question concerning discus keeping. Isn't it possible for water to have a high pH and low gH/kH? So maybe Jack Wattley's source water has a high pH but is still acidic? I thought much of the tap water in FL was acidic, maybe I'm mistaken.
It is possible. Sulawesi lake of Indonesia has that range which is why most Sulawesi shrimps fail to survive the transport from various water conditions and still fetch a very high price. That range is very unstable though. The lower the KH, the more dangerous it is as the pH fluctuates a lot.saram521;2779762; said:
High pH is alkaline so it is not acidic.
Yes. Focus on your KH, not the pH.saram521;2779772; said:
