I’m so sorry about the issues with the tank. Don’t give up...I had it in the sump section (BioCube 32) in a spot that should have been getting excellent flow right off the overflow, but it turns out that the water just backed up around it and flowed elsewhere. I'm tempted to go to the store RIGHT NOW and buy a canister.
That may be a good idea to get a canister to run the carbon for now. You can make 100% sure carbon is getting flow.

, but at least the goby made it as a surprise!! The corals as well seem like they will be fine.
