As the title states my BB tank is getting green algae on the bottom. It has been a long time coming for this tank to start to get life in it. I had to dose Nitrate and Phosphate to get up from the dreaded double 0's for awhile. My filtration only has a protein skimmer and a roller mat. It is a 160 gallon Display.
The algae feels like green felt, it is not slimy at all. The tangs like to eat it. I have about 30 snails and 15 hermits. To scratch it off you need to use your nail or a blade. It is not green Coraline.
I think it maybe sucking PO4 from my system.
I stopped dosing NO3 and PO4 about 2 months ago as things seemed to stabilize. I have been at 5 ppm NO3 for a couple of months now. PO4 would bounce between .06 - .03. However the last few weeks it has been going down little by little. My check earlier this week was .01. A bit to low for my liking.
The question is do I start dosing PO4 again or some how remove the algae? I could scrape it off but would be worried of spreading it all around. Do I dose P04 to keep levels around .04-.06 and let the tangs eat the algae until it stabilizes again? I realize my tank is still a baby especially being a bare bottom. I have been taking it really slowly and want to do things right.
