Tanks already setup, with a wet/dry. The more i learn the more i want to change my setup, heres my idea. Space is limited under the stand, thinking a 10 gal sump on left side, with a bubble trap then the rest of the space for heater and return pump. Put a 2nd 10 gallon on the right side for a fuge with a u-tube going from the fuge to the sump. Will have the drain split from the dt to the sump and fuge. Sound ok? Is the 10g too small to be worth anything for a fuge.? Thank you for your time.
