Ok...I was not dreaming. There was no possible other reason for my tank crash.
But I do want to be refounded for the loss of some of my corals. I surely hope they will refound that. I don't know what they will do for the store owner who lost 10k in corals??
Mine is also from that bad batch. It really upset me when I think that I was trying to do the best for my reef by putting fresh carbon, and that killed my most precious corals
Big lesson learned, never ever use carbon that is mined ever again. I will only use things like polyfilter or similar, never use carbon again.
