Thanks for the idea.. i will check the kH and pH tomorrow morning. I have a question. Initially Byron mentioned that at low pH levels Ammonia is not a problem. Now I do have ammonia in my tank. When I raise my kH (there by hoping to raise pH) will the current ammonia levels cause to problem to the survivors that I have???
Fist off, you are doing things that will definitely alter the water chemistry to some extent, so be careful.
Rapid changes could kill the fish, or at the very least stress them to the point they are susceptible to other internal and external problems. These things have to be done slowly.
I've no idea the extent towhich that white rock may affect hardness. I would not add crushed coral until this has sat for a couple weeks to guage the effect, with hardness readings daily at first.
Second, subsequent posts have made a couple of very inaccurate suggestions. Prime is not going to affect the tank stability (nitrification cycle). Second, salt is not going to help, and it does nothing on nitrates. Salt will counter nitrite, but one has to assess the other ramifications of using salt beforehand
Third, my earlier comments on deciding what fish were intended to point out that you cannot keep fish of differing water parameters in the same tank and expect all to be healthy. These fish come from completely different habitats. If you could get the hardness and pH to the point where it results in a slightly basic pH (slightly above 7) the existing fish would probably be fine. But this has to be done gradually over a few weeks. And you need to decide what fish in future you want--if livebearers, then work towards that and forget more characins that will never be totally happy (=healthy) in such an environment.
Edit: Forgot the ammonia question, sorry. Yes, this can be a problem. The ammonia produced by fish changes to ammonium in acidic water, but if that water changes to basic (alkaline) the ammonium changes back to ammonia. However, using Prime and similar detoxifying products changes the ammonia to ammonium in basic water. However, another reason to avoid too rapid a change. B.
