I wonder if you could help me. I cleaned my fish tank two weekends ago - after - I am ashamed to admit - about 4 months. The water was filthy to say the least. I used a vacumm cleaner thing and removed about 1/3 of the water in total. I then refilled it with fresh water. I tested the PH
level - it was about 7.2 - so I adjusted it to 7.0. I put some anti-clorinating agent ( i can't remember the name - Tetra though) in the water, along with some Cycle and some coarse salt. The water was a pinkish colour at that time - I think- due to the uneaten food.
I left the water - I had cleaned out the filter as well- an aquaclear 200 then for the evening. The water has still not gone back to clear - I replaced 25% again this last weekend and took out the amonia media from the filter and put some filter wool. I don't know what to do. The fish seem fine - not stressed or anything - eaten fine. It is just very curious as it has never happened to me before. And pink water isn't really what I want in the tank.
Nothing new has been put into the tank or changed or anything. Any ideas?
PS>> To make water more acidic - is there any househld agent that can be used? Like Bicard can be used for making it alkaline?
