Ssheipel, this is going to sound really crazy and I was born blonde, so it's just something to think about, ok?
Some of the stronger macros grow much better with some level of the basic algae requirements: NO3,PO4, FE. If one is lacking, they don't grow as well as they could. Granted, they do compete for available nutrients, when they become available, but if the available nutrition is sparse, they will grow slowly.
On the other hand, some nuisance algaes can "fix" elements better than the macros, even if one element is missing. I know when my NO3 is low, and my PO4 is up, cyano will bloom. When I fix it right for the macros and plants, the cyano is gone within a day.
OK, here's the crazy part: Some greenage growers actually add NO3, PO4 and FE! I don't add no stinkin' PO4, I just give my fish a fiesta when the PO4 gets low. But, I do add NO3 rarely, and FE frequently.
Just something to consider. You are at the crazy talk forum!
