I'm trying to make one for my pico, but 1/4 and 1/2" pipe dont seem to keep up with my pump (a fountain pump i think its around 80 gph?) is there ways to increase the flow? a 1" pipe can handle 500gph why cant a 1/2" handle 250? does changing the length of the inside or outside parts affect it? is 50-80gph going to be enough for a 3 gal? (i have zoa's and 3 sps corals)
or would a aquaclear70 refuge mod be better than a sump?
Has any one done this?

Is you air inlet on the outside wide open or have you restricted it? Also, how many bends do you have?
open and 7 bends might have to add a 8th
btw is that going to be the actual sump/refugium you'd be using? if your going that small. just go with an ac110 for a fuge. current one is too small to make use of it. especially being a pico i'd go for a hob fuge and all water changes to control parameters. i don't think there would be a huge benefit besides water volume. but why worry about that if you decided on a pico?
I think the output to your sump needs to be lower in order to increase the flow. I maybe wrong but when I siphon water out the tank the lower the tubing is the faster the water flows, if it lift the tubing up closer to the water line the slower it goes. This could be the issue??

that is also wat i am thinking but if i lower it any more it will loss its prime and wont restart , en less i make the intank U ben deeper to problem is the bottom of the tank is only a inch more.
i wanted to keep the water line at the same hight and put the ATO i a sump but looks like im gonna put a aquaclear 50 or 70 on it.. :/ btw the overflow was going on the pico not the 30gal in the pic lol so a aquaclear 110 is to big lol
set a drain on it. so that the output is lower than the outside U.

I just tested my 1/2 inch pvc overflow. My drain is a lot lower, but I use a 80 gph pump to what I did was useda plastic tube plugged one end and drilled 16th inch holes one at a time ended with three that restricted the water flow to be perfect. If you don't get let me know and ill try and help more but it works great and still have tons of current
