diy skimmer questions

im going to be building this soon and i have a few questions
Aquaria Central > DIY > Protein Skimmer

now this is going to be used on my 125 and i want to make sure its going to be skimming what it should or be more.i have 3 3000cc air pumps floating around and 4 wood air stones.now in this diy it shows useing 4inch and 2 inch piping.i did some math and it would just pass for a 100 gallon set up with 1 wood air stone.now i want to kinda over kill this in cause i do up grade to a 200 gallon plus system.only problem is i dont kno what i would have to make bigger.so here is what i am thinking.move the pipe sizes up to 6 inch wide and 3 inch centers with all 4 air stones i have.does anyone think this will work or just be a wast of time.in my head im thinking bigger pipes means wore water flow and a better " motor/pump and more stones" will make for more reaktions and doing more of the job its intended to do.at this moment in time i dont have money on for a professionall skimmer cause i bought a light and dug a hole with the wife..anyway im limited to $60 to 80 for a diy set up thats gonna have to last some time.....any input is welcome but please dont tell me to buy a nice skimmer cause i wont/cant listen right now to it.thanks

Welp, if you can't listen to it right now, I'll refrain from answering until you can.
Because that setup isn't good enough for a 20g setup, airstones don't do crap.

Nope. You may get away with the DIY pvc itself, but the pump is the biggest part of a skimmer. I can steer you in a good direction of makin a good DIY skimmer pump, but its gonna be like $50. I figured out how to make a Reef Octopus pump knock off.

You'll need a pump about like this one. Drill a hole just for the 1/4" air line, right above center. You don't want it dead center or you'll mess up the impellar shaft. Stick in the air line. Take the impellar out, and you'll need a dremel using a small cutting disk. You'll cut notches in the impellar blades, so it looks like a Needle Wheel Impellar. You'll cut 3 notches in each blade. Or you can try this DIY.

No, it won't work like the one I posted. You have to modify the impellar, thats what chews the air into a frothy foam. I've had the powerhead with air intake, thats not even close.

Just above dead center, you don't have to be exact. You just don't want the air line running into the impellar shaft. Maybe drill 1/4" above the center line. Big enough for air line to fit through.
