Nuisance Algae ID

All,

It seems I am constantly battling some kind of algae. I got rid of my green hair algae problem only to then have a cyano outbreak in my sump and refugium. I finally get that under control and then this red/brown algae breaks out in my tank. I had one urchin in the tank which may have be keeping one area clear so I decided to add a couple more. We'll see....

Anyway, anyone recognize this stuff?

cya,

Ted

Is that purple or brown?
I had some similar stuff that was brown in nature.
I only had that appear after I upgraded my lighting setup, it went away with normal maintenance in about a month.

What are the tanks water parameters, are you using RO/DI

Some patches are brown, some red and some are tan. It is only in the upper 1/2 of the tank.

System has been running for 20 months. Tank is bare bottom but I have a 240g sump/refugium on line with it. The refugium has a 5" DSB and a ball of chaetomorpha that would fill most of a 13g trash bag.

Ammonia, nitrite and nitrate are undetectable. Alkalinity is 3.1 meq/L. Calcium is 310.
