yeah, looks like cyano and a little green hair algae as well. canister's are notorious for getting nasty and causing high nitrates, could be fueling the algae issue.
How much is a "pretty good amount"? I thought the same thing, then I had my cyano outbreak and upped the flow rate - helped a lot.I have a pretty good amount of flow. I could also get another powerhead if that would help.. i just don't want tooo much flow because of my recent purchases... (colt coral, pom pom xenia, giant duncan)
http://spectrapure.com/Refurbished-90-GPD-RODI-System - this is the unit I have. Pretty popular and reliable unit.Okay, so ditch the 2 canisters and just go with a protein skimmer? Then get an RO unit? Recommendations for both would be helpful. Best value/quality ratio.
