I appreciate the help here guys. To answer your questions...
.My tank is a 50gal
.I'm not using a uv filter and have never seen the need to so please explain
.I haven't overdosed yet I don't think. Right now I have no fish in the tank so I'm using internal filters for flow. Seachem recommend 5ml for every 200L so far the most I have dosed in a week has been 6ml on different days. Is it wise to split the recommended dosage over a week and still keep the red plants red?
UV causes iron to precipitate out of the water, causing cloudiness. I have had it happen a couple times when running my U.V. filter.
