Chemiclean

Yes, works well, just leave the top off your skimmer for the additional aeration, and for the fact that it will drive you nuts emptying it otherwise.

anyone know a supplier ?

struggling to find it

Ok will look on there

Chemiclean works well, especially in my tank where I don't run a skimmer.

My current cyno growth has been there for 5 months!!! I'm trying different ways of getting rid of it, you won't be surprised to find nothing has worked yet.

I may give up after Christmas and dose the tank.

Just remember to do plenty of water changes after using Chemiclean.

Is this stuff the yellow powder?
It sort of works, you need to shift as much as you can before dosing,and this gives a false impression on its effectiveness. I found the Quim cyano control to be better, but you will lose colour in your corals with continuous dosing. The KZ stuff is good to but a little pricey. Good luck, it's a pain, but sorting out the cause rather than reacting to the effect is generally the most cost effective.

Still enroute from the States ( I hope)

In 500 gallons? So I would need to measure out 0.05 grams for mine if I needed it?

Good idea, never thought of one of those

Has the cyano gone now Jim and no harm to anything else ? (apart from your wallet)

Did it generally give the substrate a bit of a clean up too? The KZ equivalent Zeozym did, I used to put a teaspoon in my old tank once a month

I wouldn't worry, it will probably sort itself out soon enough

You need about 50 nassarius snails in there
