been battling cyno for a while now and cant get rid of it for good. only thing that works for me is a lot of water flow in the tank but its too much for my corals and they start to die off. any advice
try chemiclean. i've used it on multiple systems with no ill effects. use as directed and you won't have any problems. you'll need to do a series of waterchanges to remove the nutrients after the treatment.
Are u using a rodi? Do u have a phosban reactor with media? Do u feed alot? Are ur light bulbs old? If u fix each one of these questions I'm askin u should be able to fix ur problem
