Installing a 20 gallon sump on my 40 gallon breeder tank. Purchased the glass-holes 700 overflow and return kit. Here is the sump design I was thinking about. Please give me your feedback as I am new to sumps and overflows.
The overflow and return kit I puchased has the return drilled. Is this a good idea? Or should I just PVC over the rim?
