What do you think? Where could we improve? Rena Canister, Bio-Wheel Emperor 400, 300 watt Stleath Heater, Custom Diamond Plate Light putting out 80 watts.
It looks great and sounds like a nice set up but I too am concerned about that large angled rock.You could use one of the aquarium safe glues to make sure it does not fall, or even drill and peg it.
