So I had a bad tank day yesterday. I needed to clean the two gyres as they were barely working so I put in the back up pair and put the ones I removed in a bucket to be cleaned. Even though I didn't touch the programming, the clean pumps quickly decimated the tank. They knocked the birdsnest off its glue point on the rocks, they knocked over all of the frags in the sand and buried the favia. Instead of a relatively flat fore reef I had two sand dunes and a black acrylic desert between them. All of the fish were hiding and the water was so thick with sand particles that it was hard to see. I disconnected one of the pumps and changed the programming on the other so that it would settle down a little but I am beginning to really dislike gyre pumps. I love their flow pattern but their throughput is so inconsistent and they require maintenance so often that I'm ready to chuck them, except I can't, at least for now.
All of my frags are now behind the rocks partially protected by the Aqua Rocks that break up the flow and all of the fish have come out long enough to catch a quick bite to eat except the yellow wrasse but they went right back into hiding.
I'm pretending I don't own a tank for the rest of the day and tomorrow, sometime, I'm supposed to get my Meridian 35 so I will mount it, probably just completely remove one of the gyres and then dink around trying to get my tank back in rhythm and the corals in sane locations.
