i had some very nice zoo colonies and recently their numbers have been falling. I dont see any nudis or sundials. I did a fw dip and the only things i found were limpets a few small brown olive snails asterina and brittle stars. It started from one of my smaller colonies and now spread over into my large colony. I also recently change my lighting from 2x250w mh down to 2x150w hqi and have also noticed a huge algea cyano bloom and thats beggining to smother my zoos as well. Anyone know whats killing my zoos?
