+1 on the chemiclean. i just used it less than a month ago and my tank is still cyano free. first time in 9 months or more. I have a 75g display with a 20g sump. i underdosed the tank to be on the safe side and dosed for 60g of water volume. some of the corals didnt like it but after 3-4 days, everything was back to normal (following WC and skimmer instructions of course). its a great product!
