Hi all, I have a diatom bloom going on right now and it is driving me crazy. It is showing up on all of my equipment in high flow areas and is not on the rocks or coral. I think I can narrow the cause down to a spent DI resin in my ro/di system and silicates have caused the issue. I have replaced my ro/di filters and perform weekly water changes never missing one in a little over a year. Does anyone know how long this outbreak will last? Thanks in advance.
