Messed up and increased phosphates

[glooper]

So I made another post in another thread about how I messed up and added dry rock and skyrocketed my phosphate(0.9).

While I'm working on that I was curious about some algae issues. So before this I had some cyano and GHA in my system and algae on my glass.
However after my phosphates increased all of the nuisance algae is gone and my corals are now opening up more.

This doesn't make sense to me and am just curious what's going on. Shouldn't higher phosphates increase algae growth as well?

Not necessarily. Some algae seems to thrive in low phosphates, so increasing it can sometimes remedy it.

Sounds about right to me. If you take in consideration that most test kits are quite inaccurate at lower residual you could of be under the optimal phosphates concentration before your phosphates incident, I never allow mine run below 0.5 to 0.1 for that same reason. Phosphates are essential to all organisms in our systems an sometimes we can limit the growth of some beneficial organisms by limiting it.
