Slow down overflow rate

[Jag586]

So I've had problems in the past of fish being sucked up to my overflow and getting trapped anyway I could reduce flow rate? So it's not as strong ?

Build a bigger overflow, or restrict the flow from your pump.

A bigger overflow would be my preference, unless your pump flow is currently massively over rated.

It's a acrylic tank with a pre built overflow. The gph on my pump is something like 1200 for a 200 gallon tank

Increase the diameter of your stand/drain pipe or put a ball valve on your output if the teeth can't keep up.

Throttling back the pump will lower the water level so less teeth are exposed.

BIGGER FISH? I had the same trouble with bicher and small cichlids. I went to home depot and bought aluminum screen. Cut it to size and fold it over the weir. Had no trouble after that.

We were typing at the same time, but I used plastic pond baskets they grow pond lilies in (their black) and hot glue them to the inside of the overflow to cut down the opening, they blend nicely, and keep fish out.

The flow is regulated by how much water is returned to the tank from the pump. Slow the return water from the pump will slow the water out the overflow.

+1 to both Gary and Bruce. Block off the area around the outflow or screen the opening. Assuming it follows normal physics (Inverse Square Law), the amount of the force near the intake drops dramatically as you move just inches away.

So dr strange kinda like a river with a waterfall at the end up stream it's slow going and smooth but closet you get to the water fall the faster the water movement is.... The reason I am even asking is incase I go with a mbuna set up when smaller they may not make it
