I got a reef running and green hair algae is getting out of hand. My question is, will the algae effect any of the coral? It's a 46g mix reef.

 

[Reefing Madness]

It will overgrow the coral eventually.

 

[That one guy]

Will the coral die? Am trimming as much as I possibly can, will that still be an issue?

 

[Reefing Madness]

Yes, it will overtake the coral, and eventually kill it.
Trimming it won't hurt anything, but you have to get rid of it.
Whats your phosphate and nitrate readings?
