Ok, so I've had my 29 gallon tank approx 2 months now.. I have 5 juvenile cichlids that seem happy, water is crystal clear, levels all good. Approximately two weeks ago I noticed brown algae growing & eventually covering the majority of one of my rocks. I checked the nitrites and it was pretty high so I performed a 50% water change and figured I'd give it another week to see how it reacted.
Well... I don't think it's spread on the rock, but now I see some brown algae starting to grow on my plastic plant (please don't rip me on this one). It looks like I'll need to take the rock & plant out to give them a good cleaning.. & correct/re-test the levels again.
My question is.. am I going about this the right way? Anything else I should do? I thought about adding a sucker or otocinclus to help keep that in check, but I think I'm stocked at the max right now.
Any thoughts/suggestions would be appreciated.
