I had a fish that went under recently... my 9" diamond rhom... anyways the water levels were as close to perfect as possible. I just bought a large piece of driftwood and I did soak it for like half a day and then put it in my tank. the wood still leaked out that stuff and well when I woke up I found a dead p in my tank and the water was discolored. could that be the reason? I had the water temp at 78 degrees. First time this has happened to me and I want to blame the stupid wood..
