What are your NO3/PO4 levels at? With most algae no. If we are talking diatoms or cyano then possibly. I would say as long as you don't let PO4 reach 0 you should be fine just work on that clean up crew. If acros still look good I doubt you've bottomed out on PO4 but it always worth a test.So are we saying that my recent algae growth is contributed to no Phosphate?
Also, my tank is only about 3 months old but I cycled with microbactr7 and had an initial diatom/ algae bloom but it cleared up.
