Use RO water if you're not already. Increase the waterflow in the tank. (I find 2 PH's work best) Cut back on the lighting time for awhile, or if you don't have corals turn them off for a few days. If you have fish, try feeding them every other day once a day and don't overfeed. I'm not a big fan of bio-wheel filters, I'd get a HOB without them.
Your tank is new so these outbreaks are normal....be sure the water parameters are good also and you can beat it!

Oh yeah..... do weekly 1 gallon waterchanges with RO water. :happyfish
