You say your system is drilled, is it for the sump pipework? or closed loops? They are two completely different things. The closed loops are powered by fearsome air cooled pumps (ie, Sequence) that produce immense flow rates. Rendering the use of power heads obsolete = no power cables for your fish to chew.

Thanks for posting that link. It is drilled for a sump, so therefor not a closed system.
Switching to a closed system sounds like the way to go, however I have never drilled a tank before, and am really nervous doing that (but I could get someone to do it for me). Do you have any links or diagrams to a closed loop system?
Below is a picture of the tank. Any, suggestions on where to put the drains/returns If I were to switch it?
Thanks
