Plumbing issue with 2213 on 20g

I have looked at about 20 posts and have not located an answer for my question. I have a 2213 on my 20g with all stock tubing and have found that their spraybar connect SUCKS! So with that being said my questions are as follows,

1. Can I use a 1/2 inch coupling to connect the Eheim 12/16 tubing to custom spray bar?

2. will a 3/4 inch custom spray bar cut down on the movement inside the tank resulting in loss of circulation of water?

3. Would it be better to go with the Lifegard Customflo System or the Eheim Water System Install set and cut out all the DIY work?

On a 2nd note, I am getting a lot of impeller noise. I do not see that there is any air in the canister and am wondering if there is any way to force all the air out of the canister. I have moved it all around and found that if it tilt it about 20 degrees in the angle of the output hose the noise goes away. I have taken the impeller out and reseated it a few times. Any ideas?

It is nearly impossible to locate a 12/16th connect here as the small and big box stores do not carry metric and that is as close as I can get.

If you have other solutions for an intake and output DIY for a 2213 on a 20 Gallon tank it would help. Pictures work wonders for me.

Thank you

hi buddy, i will not answer one by one your questions, as i dont really understand some of your issues. However, i made a sketch for you that can be helpull..

u need to spend about 10 or 15 bucks for this, no matter the size of fittings, you use the same only adapt to your needs, just let me tell you a little bit of hidrodinamycs, at bigger area, slower current, so if you use a 3/4" plumbing, less current (speed) you will have as with 1/2", but more volume instead. (not too much). if you want to spread water for good circulation, use smaller holes, otherwise use biger, usually we stuck with 1/2" for small or bigger than that for powerful pumps and big volumes.

im not sure if 2213 uses 1/2" hoses, but that doesnt really matter, you just need these fittinsg on every end of hose coupling, and this will let you manage your plumbing as you need

unles you have a in leak, air noise have to disapear in about 1 or less hour (cavitation). air is absorved by water, but having an inleak is not common. wait a little, hear again.

sometimes, the plants bubbles so much that the filter is clogged with O2 inside, but you will need strong light and god ferts routine (EI) to make this happen.
