Yeah, definitely try that first, for sure. I cut back my feeding to every other day for 2 wks and I actually pointed my powerhead directly on the spot that had the cyano and I continually suctioned it out as it grew. But even while doing this, it still was growing and spreading quickly. I then finally gave up and went with Chemi clean. It killed it all in 3 days. Yes, it probably killed some other bacteria also, but it did not affect my levels in my tank at all - no cycle or anything. Everything stayed 0 with amm, nitrates, ites. So I am impressed with Chemi clean. The reason I picked it is b/c it does not have any antibiotic in it. Most other anti-cyano have erythromycin or some other antibiotic.
