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.
