Thanks dude. It's been through some rough stages, but I think it's settling down now. I'm going to start fragging a few bits soon as a couple of pieces are close to touching.
Well, bit of a **** night with the tank. At 10:00pm, the lights go from setting 10 on blues only down to 6 which is just the 3xUVs. As soon as it switched, the UVs started flickering like a lighting storm. As I pulled the chair out of the way to switch the unit off, a wrasse flew passed me and landed on the chair. It was fairly dark, but I am sure it was a yellowtail. I quickly scooped it up and put it back in the tank. Lights turned off and set my T5s to come on from 12pm today until I can pull the evergrow unit off later and see what's wrong. I'm hoping it's just the driver for the 3 UVs which is broke because I have a spare. Guess I could always amend the setting to go from 10 to zero though, effectively cutting out that driver.
Then, the missus messaged me this morning with a pic of my red fairy wrasse which was on the chair. She seems to think it's the same wrasse who jumped last night
I can't even put a jump net on the tank because of how the lighting legs rest on the tank sides. It's these kind oof set backs which make me want to just drain the tank down and bin it off.
