I just started a tank about 2 weeks ago. A 70gal custom built by me anyway I dirted the back half with organic soil and caped with play sand ( white ), the front/foreground has flora max as a sub that's it. I have one peace lily,DHG (dwarf hair grass), along with some glossostigma. When setting up the tank my hose pipe burst so I couldn't wash either substrate but a few water changes cleared that up, I do have a divider in there about 4" tall an its yellow acrylic so this is the only thing I can think of as being the culprit besides not adding the water clearifyer that came with the flora max. Any ideas as to why I have yellow water with only rocks in my hard scape?
