nice about 300g or so
I would say the drawing of pipe on the right side is what they mean, if you increase the diameter of the inflow is will surely increase the water flow. I am not a plumbing expert though.

Yes, the one on the right will flow more water. You just don't want the bottle neck really high. You'll get a slight increase, but it sucks air worse (I can't explain why).frootloops;3955015; said:Is this what you mean by a larger riser? Because I have no idea what it is..
Will the pipe on the right take in more water then the pipe on the left?
Dane;3955486; said:This is what I had in mind. Basically replace the 1" overflow with a 1.5" or 2" overflows. At the bottom you would simply need to use a reducer for your 1" fittings.
Anyone else thinks that this is a good idea? If yes, then I'll try it.
Ok so I ran the pump today.
All those long pipes really did affect the flow rate of the overflow. 1 pipe is now able to push 520 GPH but it very very noisy. Kinda like a farting noise which is pretty annoying.
Only happens when running on max capacity as I closed off the 3 other overflow pipes.
The way I tested the flow rate is I took a 5.2 gallon fish tank. I placed it under the pipe and timed how long it took for it to fill.
Since the sump was on the left side now, I had to transfer the pump to the left side as well. I think this caused the pump to run very poorly.
I measured the water coming out of the 2 overflow pipes I opened and the flow was only 5.2 gallons for every 36 seconds. If my calculation is correct, that equals to 520GPH. Is that right or did I mess up my calculations?
I also installed 45 degree elbows under the overflow pipe instead of the 90 and the numbers were the same.
If I was to install 2 pumps of the same rating then that would just be 1040 GPH for a 380 gallon tank w/ a sump holding around 50 gallons of water. Do you guys think that's enough? I think 2.5x turnover may be enough as I plan on doing a drip system as well.

Your math is correct. I came up with 520 gph also. I've been running lower turnover rates with good success. The quality of your filtration is significantly more important than the turnover rate. The drip system will help greatly with the water quality too.

Well that's great news for me. How low a turnover rate are we talking about here?
May I also know what kind of tank maintenance you do with your low turnover tank? How many gallons in water changes per day, how large is the tank, stocking, etc..
Also, does having a low turnover rate affect mechanical filtration that much or will I still be able to maintain crystal clear water? (2.5x turnover rate)
