Tank with no Overflow

[Kasey Grohowski]

My buddy has had a 220 for a couple years now, his overflow is siliconed on. I am planning to drill my tank and add a modular marine low profile overflow. He says I don't need an overflow, just drill add bulkheads and powerheads near the surface for agitation. I am not planning on doing this, just wondering if it would actually work.

Drill plan is good and a tank of that size, I highly recommend overflow to sump for controlled and simple maintenance

You friends way will work, but it will just not have an emergency drain if that drain gets clogged.

Saltwater aquariums are designed with overflow off the tank surface because proteins/dirtiest water floats to top. Unlike freshwater where it sinks

If your friend has bulkheads near surface with no overflow box it is noisy. If he has a valve on the drain as would be with bean animal or herbie plumbing, he’s not getting all of the water from surface

Plus who wants to look at pvc pipes in the display

I have wondered about this same topic before and the one big thing I see is the wiers will stop your fish or CUC from getting sucked down into the sump.

Fishes or CUC will not get sucked down if you put a drain cover or a 90 degree pvc facing up on there...
