skimmer plans need input

I want to make a skimmer, it will sit under my tank next to my sump but I dont want to drill the sump so could someone tell me if this idea will work

its a simple mspaint picture I just need an ok on the basic design pretty much just the exit line im wondering if it will travel back up and over the lip of my sump which is a 10gal the pump will be a mj1200 because I have one lying around

k. so there are a cupple of problems with this design (this was the 4th design i tried out of 7 befor finding a good design. so the problem is that for the water to flow back into the sump the output line needs to be gigantic(around 1 inch pipe) or the skimmer has to be high above the sump. (from trial i found that the base of the skimmer has to be at the top of the tank) what will happen if you use this method is that water wont flow back to the tank fast enough and it will come shooting out the top. so to make it work i would eather use a slow moving pump(slow water movement is good for skimmers anyways), make shure the return pipe is as large as posible, and defenatly raise the skimmer (at least a cupple of inches)
oh. i just noticed something else. i would switch the output and the input so that the input goes to the bottom and the output comes from the top. this is very important. im having a hard time explaining why but for it to work like this the water needs to spill out the top as an overflow. i know that it wont be counter current that way, but the output has to come out the top.
the only reall way to know is to make it and see. sory for the long post and good luck

Hi wahoo_drew. Have a look at the follow link and see if this could be your ticket. It is a very good article for a DIY skimmer. Good luck.

Thanks Serge, I've seen that skimmer and would love to build it but I dont have the time or patience to build that. Also that needs a really big pump to run and I dont want to buy a large pump just for a skimmer but thanks anyway

so what i ended up doing was using a diffrent method compleatly, that just sat in the sump. but thats cause im lazzy, and it was the simplest to construct, because i didn't have to wory about leaks. the plan that you have should work if you switch it around. look at the pic below.

for some reson i think lots of bubbles will be released to the sump.

BTW i cut the parts for the diy skimmer serge posted yesterday. I will do some different things for ease of cleaning and have to use the lathe for that later next week. I will post results later.

bubbles in the sump are not a problem because the skimmer will be in the first chamber and there are baffles so it wont matter.

so foma what if I put the input at the top also? or maybe ill put it at the bottom and angle it to get it spinning

also think a maxijet 1200 will be strong enough to power a skimmer like this?
