Hi everyone trying to confirm what type of algae I have here or if it is more than one type. I'm no expert and some of it looks non-descript. Any help in getting rid of it will also be appreciated..

Tank is about 6 weeks old and is 90g, Pressurized C02 & Reactor, 4x t5HO 54W geissman lamps 9-10hours day. C02 stays in the green sometimes yellowish. 0 Ammonia, 0 Nitrites. Mix of Flourite and Caribsea Eco Complete substrate. 1 HOB filter and a Rena XP3 canister both running full time with mostly mechanical and biological media although I have been occassionaly running carbon and some Purigen.

Iron 2ppm. Nitrates 8-10ppm, P04 .5ppm.

Using RO water but adding RO right for the traces and then dosing Nitrogen, Zinc and Mn separate with a liquid fert. Unfortunately none of my LFs have proper ferts but I got some from RexGrigg which are on the way since I have not been able to dose Pottasium for a while and the other traces. I dont know how much of an impact this is having on the plants and therefore allowing the algae to outcompete but the plants are growing great and pearling etc. Unfortunately I wont get the ferts for at least another week.

I had some BGA a few days ago which was starting off not spreading too fast but I still did some spot treatment with some Hydrogen peroxide which killed all of it but unfortunately didnt do much to the rest of the algae. Everything else was fine. There is a window close by which stays shut but still leaks some light but none of the algae is close to it so dont think it has too much effect. I also have 3 1" Ottos, 2bristle and 1 clown pleco which are always busy but not having a big impact on the algae.

Ok thanks guys, seems I have a mix of fuzz/thread and staghorn. My C02 is good so I'm putting it down to my plants not getting the right mix of ferts and possibly leaking some back into the water. Will have to try and battle it till I get my ferts here so I can help the plants. I might drop lighting a bit until then.
