Thanks. The problem is that the problem was BAD. I cannot believe it got so bad so fast. The new water system is great, and the tank is clearing....slowly. The bad part is that I lost all my corals too (I really did not have that many, but...). My other fish are doing fine. Monetary problems have made it impossible to do anything but scrapings and water changes, but I am starting to see real progress. The rock is clearing up, and so it is not spreading to the glass as fast or as bad. I think it will be a few more months at this point (because I don't want to tear up the tank) before I think about replacing anything. First thing will be getting more snails. This year should be better money wise also. The surgeries and stuff cost me a lot last year, but I am getting caught up, and should be able to put more into it. I want better lighting also. This time I will work on the tank first and be more patient when it comes to stocking it.
