Red algae????

[rdefino]

It's a 75gal FOWLR About 4months old. Protein skimmer, oceanclear 325 canister, 80lbs LS & 95lbs LR. I'm noticing some redish algae. Not alot, but some. Should I be worried?

Thanks

Got a pic?
What are your water parameters including PO4?

 

[rdefino]

salt 1.023
Nitrite .05
nitrate 2.5 on the low range using Red sea marine lab
ammonia .25
PH 8.2
ALK on the high side.

How do I measure PO4

I'm still trying to figure out to attach a picture

You measure PO4 bu using a PO4 test kit. Excess algea in your tank is ussually a sign of too much nutrients. This is often due to a high PO4 level. Test your tank water and source water you use for top-offs and water changes.
