brown Coraline? not an algae i'm familiar with

[uh.oh...]

I know about the turf, that's from the new lights. I guess the brown stuff is too, but what could it be?

Def an algae you'd want to remove. Use this local saying to help you out with algae "If it's brown, flush it down. If it's yellow, let it mellow"....but **** fine looking corals BTW.

Thanks! They've got me dosing alk and calc every other day, but the colors and sizes are really starting to improve. Tek elite 6 bulb t5 gets the credit for that.

You need to stop dosing. You are having enough troubles with the algae, and dosing will just throw your other parameters out of whack if you aren't testing them. That and from all I've witnessed it takes one heck of an overgrown coral tank to require dosing.
