Effectiveness of chaeto

[Xenoch88]

So, I setup a refugium/Sump for my tank, and moved my chaeto that had been in my display tank to the it. within 24 hours I discovered that I had made 1 small error in the design of the overflow as it is to high thanks to the hood (overflow box that sits in a groove of the hood box, that has a removable top).

Needless to say the sump has been disconnected for now until I have a chance to fix it, (probs this weekend) and since then I have had an algea growth in my display, glass, rocks, everywhere. I have moved the cheato to the display tank for now, and lets see if that helps.

Any other advice would be great, currently I am watching my snails chow down on the algae like its lunch (which to them, it is!).

Also it is a brown algea, cyano perhaps? not sure on ID.
