I purchased a used Oceanic 29BC a few months ago. At first it was running great! No problems whatsoever...Now..not so much that it's a problem but, I have a layer of green algae that grows against the glass. I've never had a biocube before, my other tank is a 100G which my dad and I will be updating to a 190G, but thats another thread...

Is there anything besides cleaning it or is that just the way a BC runs?? Like i said..it's not really a problem, I clean it once a day which isn't completely horrible..haha. Any tips would be great yall!
