Re: waters went murkey

Hi
OK it's a bacterial bloom as the tank is now cycling from scratch. The murkiness will clear in a few days, BUT the water will become increasingly toxic to the fish over the next few weeks until the tank has cycled.
You need to test for ammonia and nitrite every day and change enough water for fresh, dechlorinated and warmed water to ensure neither ammonia nor nitrite exceed 0.25ppm. To help detoxify the small amount of ammonia and nitrite still present (you need some to allow the cycle to happen) use Seachem Prime in a double dose sufficient to treat the whole tank volume at each water change. This may mean huge water changes every day for a few weeks.
This article explains what to do.
The other alternative is to order
some of this and put it in your filter. It will remove most of the ammonia and nitrite, leaving just enough to cycle the tank. Be sure to get this exact product, and to still test the levels daily as the polyfilter will become exhausted and need replacing until such time as the tank is fully cycled.
