Medium Tanks (31-100gal)

This is a tank we set up about a year ago, but have no desided to breakdown drill and sump as my originsl idea did not work quite how I wanted.

I thought having a weir on the back corner of the tank would be a good idea to hide equipment, reduce water level drop in display part, have chaeto in wier and stop micro bubbles from skimmer using to external canister to pull water from Wier back to display.

Well it worked, but little issues here snd there, mainly skimmer freaking out due to...
