I'm going to be moving my 150G soon which means I will have to drain the tank. Everything will be in transition which got me thinking of switching out the overflow system.
The aquarium is an Oceanic 150G (5'x2'x2') with two overflow towers each with holes for two 1" bulkheads. The system was originally designed for one drain (durso) and one return. The durso drains are far from silent driving me to find a better solution.
Option 1: Keep the internal overflow and convert both overflows into herbie overflows. Drill 1 or 2 new 0.75" bulkheads in the back glass for returns (or run them over the trim)
Option 2: Remove the two internal intakes and try to not damage the seal silicone. Then patch the holes in the bottom with bulkheads and plugs. Drill the back glass for a larger ghost style overflow and return bulkheads.
Option 2 also enables me to reseal the aquarium. The silicone looks to be in good condition which is surprising since I think the tank was manufactured in 1994. I don't want to fix something that isn't broken and induce new issues. I have resealed a large aquarium before so that's not a huge issue, just more of a potential roadblock.
I would prefer having a beananimal overflow like on my reef tank but a double Herbie will probably be just as good, if not better. A ghost overflow opens up a lot more space inside the tank and looks sleeker, but would also mean I now have extra bulkheads in the aquarium. I prefer having the back drilled to minimize some flooding risk but since the tank is already drilled in the bottom, that point is moot.
Thoughts?
