Aquarium Advice Addict
my 29 gallon which I'm trying to makea show tank keeps getting yellow and more yellow and it stays yellow. I know its not the driftwood anymore realising tannins. I put it in a seprate bucket for about 2 weeks and the water stayed clear, nitrates are only at 10 ppm. nitrites 0. phosphates 1ppm. I'm guessing nitrates right? I know its the reason my walls are growing algea near the bottom and middle. I have a cascade 700 with the black sponge it came with, fitler floss on it, a coarse sponge and some bio balls ( like 3 ) which is nearly not enough, any suggestions???? I've done water changes and gravel sweep like crazy!!!
