Check out the RO/DI article I recently wrote in the "New to the Hobby" forum. It covers how RO/DI systems deal with chloramines.

After you read the article, this will make more sense; if there is ammonia making it through the DI resin that could cause cyano. Cyano does like ammonia. However, if there is ammonia making it into your reef you would probably be seeing bigger problems.

Cyano can be very persistent. The best method I've found is manual removal - week after week.

Ok thanks for that article, just seems I've been battling this cyano for almost 2 years since I started this reef. I've tried the siphoning and that does remove it but a few days later it starts to come back to the same spots again.

Have you been using H2Ocean the whole time? I just started using this salt and since day 1 of using it I have been having cyano issues.

Yes I have. My pail is almost empty so I will be trying something else

It's just that after every after every water change the cyano gets worse so I'm assuming it's something I'm putting in.

What are you carbon dosing?

Flow doesn't really help it just helps spread the bacteria

I'm th gonna go out on a limb here and say your carbon dosing is prob a bit aggressive and is out competing your po4 , this can cause Cyano
