Yep, definately the most uncared for tank I've seen.....................................................
NOT!!!!
It just goes to show how differently we can all run our tanks and still end up with our own little parts of the ocean. I've been considering getting a little HOB skimmer for my new "Love Shack" but on re-reading your thread have decided not to. I just needed reminding that I managed without a sump or skimmer for 3 years!!!
Grins, the donut is a sea squirt of some type, very hardy have had him almost since day one, was the inspiration for coming up with a design not to overflow the display. He managed to get into the overflow, up the tube, and then down getting wedged where the bulk head is. He was too far down to get from the top, so had to undo the bulkhead from the bottom. Had a friend staying over that weekend and she is like really tiny, I still can't get the image out of my head with her gripping onto it with both hands under the tank while my wife and I tried to pull her and the squirt out as it was really, really wedged tight.
Well you probably guessed it, no water change in 269 days. Lost twinspot, I think a new tunze got him. I have added 3 of those little ones which you can hide at the back. They are great because you just magnet them to the glass and drag them down. I would prefer have a bunch of those hidden than a large one. Added a heap of aragonite, amazing how quickly it gets populated. Here are some photo's.
hard to believe it's been so long since you've done a WC and the tank looks so good! it's a cool experiment i guess but i just want to grab you and shake you and tell you "do a water change!!!" lol
