So the berghia ate all the aiptasia. It took a really long time for it to happen. I thought I got ripped off then all the sudden I saw those critters EVERYWHERE, and the aiptasia disappeared within the week. Then the aiptasia all disappeared too.
Around this time bryopsis appeared again. I know EXACTLY where it came from and I have been fighting it off ever since. I'm not going to blast them here, but a well known place. Also turf algae. I was spot treating with H2O2 and it would die and come back. So I got some fluconazole. I hit the turf with H2O2. It took about 200mL of H2O2 to spot treat it all. Then pulled the UV, skimmer, and carbon offline. Dosed the fluconzole then waited. Within four days all bryopsis and turf was white then dead. I waited three weeks, did a massive water change then put everything back online. My Macro algae took a hit but seems to be OK. The corals are fine. Fish are fine. So hopefully everything just stays as is. I am adding more macro to the sump later, and probably some more corals finally. I am just so sick and tired of fighting all the algae all the time. It sucks the fun right out of this hobby. This winter I am going to probably redo my plumbing. I really don't want to but I have salt creep around the bulkheads and I need to plumb in this UV. I'm tired of it hanging off the side of the tank.
