Can somebody please help. I have an acrylic drilled 240 gallon with dual overflow. Each bulkhead is connected to 1 inch pvc pipes running to a separate DIY wet/dry trickle filter made my those sterilite trays from walmart filled with media. The issue im having is one of the sump fills up faster than the other; however both sumps have the same amount of drilles holes and media. For my return pumps, I have two Mag 18s. Im mystified right now. Please advise because I am stump.

It is almost impossible to run two sumps with two pumps on one aquarium with dual overflows without having the sumps plumbed together. Your two pumps would have to flow the exact amount of water at all times, which is almost impossible to do. You have to connect the two sumps.
Why do you have 2 separate sumps?? why not just one big sump with one pump. Normally sumps just use 1 pump. The amount of water the pump pumps into the tank should be the exact same the overflows back to the sump. This is how that works and never have this overflow problem. What is happening is one overflow is flowing faster then the other filling more water into one sump flowing more water then that pump can pump back. So connecting them would basically give you one sump so no matter how much water one overflow flows it all goes to the same sump so both pumps can pump the same water. I think if you connect the two sumps you should just use one pump.
Drill a hole in each sump. Install two bulkheads with a connecting pipe between them. Or you can connect them with a U shaped tube.
That will not work. You will constantly be adjusting the flow and eventually one of the sumps will overflow.
yep. the slower pump can't keep up with the flow from the faster pump. connect the sumps or convert to one.
+1. A larger single sump with two pumps would be the best option but connecting the two sumps would also work.
