Houston, we have a problem!
The last few days the return has been glugging away a bit (going down the emergency overflow or whatever). Initially I wondered if the vents were clogged up, but nope, they're clear. Then I thought maybe something is clogging up the reefmat, causing slow flow... never did I expect to see this.
There was literally a carpet of aiptasia down there. Unbelievable. I know I had spotted a couple of big ones in the DT along with a couple of smaller ones in the sump, but this was unreal. Never thought it would be these things clogging things up!
I'm going to have to pull the whole unit out today and thoroughly attack it with a brush/hot water or something in the sink to try get them all out for good. Then hope they don't come back!
I also need to go and buy some aiptasia X to try kill off the big ones in the tank and also thinking about possible getting some peppermint shrimp to run around in the sump and possibly a filefish for the DT.
