The DIY filter I was building was too big to fit under my stand (should have checked that first but oh well).
Anyways I have a model 150 wet/dry eshopps filter that has dual inlets on top and I have a mag 18 return pump.

My question is how should i handle the mag 18 since I think it will for sure pump more than the overflow box.

I see two options.

1. The overflow box has two 1" outputs. I can combine them into a 1.5" pvc and hard line it into one of the inputs and on the mag 18 T off a bypass and run it into the other inlet on the wet/dry filter controlled by a couple ball valves.

2. put a ball valve on the mag 18 and restricting the output flow (don't really like this option).

3. I am open for other options that don't cost a lot of money because the wife is seeing red with the more $$$ I spend. hehe.

Thanks in advance for any advice.
 
I always had both the valve and bypass, the valve for maintenance. The bypass will allow more contact time with the bio media. I would just bypass, but put a valve on the bypass to control it.
 
cool. that is what i was thinking. Do you think running the overflow which has two outlets which are 1" into a 1.5" T and 1.5" pipe and into only one outlet on the bottom will be a problem?
 
I think i see what your saying now. This is what I would do, be ause a mag 18 will pump less depending on head height. Run two drains and hard line your pump w a ball valve to adjust flow if need be. There is a chance w head loss that the two drains will flow enough to keep up w the pump. Make sure you have two u tubesthat can handle the flow as well
 
sorry...i will try to clear it up. The overflow has two outputs and the w/d has two.
I want to T down to one pipe on the over flow and go into one of the w/d inputs and then run the bypass into the other.

I don't know if it helps or not but the outputs on the over flow are 1" so I ran them into a 1 1/2" pvc T and then ran the single 1 1/2" pvc down to the w/d input. I don't know if the 1/5" helps or not since the output and input holes are 1"

I guess I could just go down with 1" into both holes and on one of the inputs to the w/d put a T in and run the bypass in that way.
 
Here is what I have now going from 2 out from the over flow into one of the two inlets on the w/d system. How much would this setup restrict flow?

I think you you're over engineering here. You have to understand head loss. Since your tank is not drilled, you'll have at least 3 90s to get the return line from the pump, to the top of the tank, down inside the tank and one to have the water output horizontally. Each 90 I'd roughly one foot in head loss. Include that w the total height your pushing water (let's say 4ft because chances are our stand and tank together are at least that) your looking at somewhere around a total of 7' head loss.

According to a chart I found on marinedepot, at 7', your mag will be flowing 1060gph which two 1" drains can easily handle. Even at 5', you're only flowing 1200gph
