Marko I was looking at your set up and notice that you have the air lines connected to a hose where is that hose going too. is that being fed from outside. and if you throw more air with that its going to suck more air on your air valve. having that hoses on there will minimize more air being sucked in

Ill post detailed pictures when I get home

NO what I was referring to was the black valves that water is pushed through if you take them apart some things if your not paying attention you can put the actual beckett in wrong.

and I now see what you are referring too. for the air, you have it straight coming in from the Air pump. you should have a air valve connected to that air inlet when the line goes in to. this is how you adjust the air and the amount of air because Becketts will create a vacuum and cause air to be sucked in. the more the valve is open the great amount of air is able to be sucked in.

There is a valve on the output of the air pump.

Before I had the air pump the becketts were sucking in air. But not enough for my liking. I wanted more more more muahahahahahah

But the Beckett valve only fits one way. It's bigger on one end than the other and it has gaskets one side. So they only fit in one direction.

When I was running a Beckett skimmer I used an Iwaki pump. They are excellent high pressure pumps. Here's a link http://www.jlaquatics.com/product/wp...ater+Pump.html
If your looking for an in sump type you might have to go with a Red Dragon $$$

Lol don't even get me started in red dragon! But thanks for the suggestion

yes please done get him going

ok here are the pictures.

Pump is at the far end of the sump. inlet is 1.5" and outlet is 1.5" but i reduced it to 1" for 1" vinyl tubing.

Tubing runs under the tank and into a Y where it splits into two 1" hoses

the vinyl hose is connected to a PVC 90 and then goes into the becketts. The 2 smaller hoses are the outputs from the pump forcing air in

water and air mixture travels down the "twisted" tube and then the mixture is ejected into the skimmer body

and this is how much SCFM i get with the air pump running.
Without the air pump (just sucking from beckett) this reads 0

No air pump - gauge read zero
Air pump added - gauge read 25 or whatever.

hmmm... Question:

Why even use the Beckett?

I'm guessing removing it would increase your flow substantially and while that might not be desirable as airflow wouldn't increase it would allow for a smaller pump to be used.

Oh and PS flow from that pump will be quite limited by the 1" vinyl line.

sorry that was a typo. without the air pump it reads 10

i was told that using a 1" tubing will give me greater pressure than if i had used 1.5"
