Cuteness! Good on you @NickT.
Guys I'm not sure if you know but SPCA functions solely on donations- no more government funding.
I may be the only person that didn't know this but please contribute to keep them up and running.
Sorry to hear that at @method1. Such a sad flaw in such a good tank. Thanks for letting us know u found the problem tho. Perhaps contact ehpro or the vendor to see if any assistance can be offered?
FYI. For those that feel that the AFC ring is a little loose and would like it tighter.
If you remove the afc you will see a small screw in the base that acts as the stopper for the afc ring. Screw it out a little and place the afc ring back (continue this until desired tightness is achieved).
