HELP! Can anyone identify this algae?

[stevesherrin]

I changed to a new ai blade grow and have developed this rust orang/brown algae with long tendrils. Any idea what it is/how to get rid of it?

You are going to need 100% white light no blue ..... Need better photo.
From this it looks like cyano or diatoms. But really need details on tank history, equipment and a better pic.

This orum is awesome, the more info the better we can try to help.

10 month old 75 gallon tank w/20 gallon sump/fuge. Parameters have been stable for 3 months or so, very little algae blooms until I switched lights. Here are some photos under cool white only.

Thanks, "just switched lights" from what to what ?

What is your long term goal. LPS, Softies, LPS.... Fish only ?


What all filtration are you running?

What is your maintenance schedule?
