Almost wiinning the battle with cyano due to new tank syndrome.(they come in ~4th month mark for me)
Adjustments I made to combat it includes:
Reduced photoperiod.
Weekly water changes.
Changing from dry to wet skimming.
Bi-weekly changing of filter-socks to eliminate detritus buildup in the sock
Sucking out the cyano layers during water changes.
Lastly,have a reliable CUC:)
Do bear in mind that cyano is a bacteria and not an algae, therefore, there are recommendations to use antibiotics to combat it (Maracyn/Erythromycin). However, when using such antibiotics, one gotta bear in mind that you might be killing off some other bacteria as well. I'd suggest it as a last resort or not at all;)
