i think youll find marko, like i said it does happen to us all cyano is almost always caused by excess nutrients even if they dont show on your test its just that theres not enough in the water column to show on our crappy test kits(especially phosphates) and as the years go by theres bound to be some times where we arent as diligent in the husbandry part of the hobby even the most meticulous reefers cant keep everything perfect forever theres just too many variables to take in to consideration.
cyano wont dissappear over night and if you use things like red slime remover its only a bandaid fix, im sure i sould like a broken record lol but some elbow grease, water changes and replacing of media will help bigtime and with in a couple weeks you will notice everything go back to normal and then you have the fun pleasure of wondering when you can do it all again lol.
turkey baster is your best weapon, SUCK up cyano mats and blow off ditrius and hard to get cyano on rocks, followed by some old fashioned water changes.
you can reduce your photo period but if its a nutrient issue lighting will only help a bit.
youll find that doing just one of these things wont remedy it but doing them all will surely end up with positive results it just takes some patience.
like the other good reef saying goes " nothing happens fast in a reeftank but disaster"
cheers buddy im sure youll have it licked in no time
