These couple of months I've been plagued by brown algae. The tank was set up in April, so its been only about 3 months, I'm doing plenty and plentry of water changes, about 25% every two days, but it got so irritating that I thought I'd check my water to make sure everything is ok.
So anyways my nitrates/nitrates are good, ammonia zero, kH is very low, pH about 6.0, which is slightly worrying, but cos I have discus, tetras and rams they all doing good.
The thing is my phosphates are 2.0, which is probably why my algae is going out of control according to the guy at the shop. So I bought phopho-zorb to try and reduce it short term. The question is, how would I decrease phosphates in the long term?
And should I be worried about the water hardness? Oyster shells, and kH stabilizers were his solution but I don't particularly like playing around with the pH if I can help it. Apparently water in my area is soft, which is a complete opposite from Dunedin where I came from so I'm not sure what I can do about it. Any thoughts or advice?
