I recently purchased (used) a 150 gallon acrylic tank which will be my next reef. The tank didn’t have overflow boxes but was drilled for 1.5’ bulkheads (2) in the back corners. I considered buying the ghost overflow but wasn’t excited about having to buy it, drill the tank, plug the existing bulkheads, etc. so I went to Lowe’s and bought 10” of 1.5’ PVC two 1.5’ three way fittings, two caps, and 1.5 bushing.
This is an extremely easy overflow to make and each drain will handle different amounts of water (primary and secondary). The drains are straight forward and if you look in the pics you’ll see the bushing I sanded down to fit inside one of the three way fittings. The “weir “ is 1.5’ pipe I slotted with a chop saw. Overall I have about 2 hours into this and I should get excellent skimming and not have to worry about my tank mates getting stuck in my drains. My last step was to paint it black.
I just thought I’d share this in case someone else is needing to build an overflow and is looking for ideas.
