No I haven't removed the Bio-wheel. Should I? We ended up getting 2 Astrea snails, a cowrie snail, and a sally lightfoot crab that will probably go back to the store (or fed to the cats) as it's really agressive towards anything that moves (even tries to get your hand through the glass) and has eaten one of the fan worms and the two mini stars are now MIA. On the good side, it did get rid of the bit of bubble algae that I noticed on one of the rocks and has been busy eating the diatoms.
I installed a 32w PC retrofit this past weekend. What a difference that made. I also found out late last night while flashlight gazing, that someone has released the Krakken in my tank! There's a monster bristle worm that's as big as my pinky (and I don't have skinny, delicate fingers!) This worm is huge!
