Great DIY skimmer! Very inspirational.
I don't know if anyone replied to an earlier question, but I believe the Euroreef skimmers are designed so the water flow goes through the venturi first and then to a needlewheel pump in order to break up the bubbles even more. Otherwise, the needlewheel wouldn't really do anything since no air would be injected yet.
But, I am no engineer. Heck, I can't even assemble lego properly.

Wow...the best thing I've seen in a long time.

Wow...!!!
What a great idea that bioball mod is.
I whipped one up in 5 minutes using a straight razor blade to cut the pins. I'm using it right now on my Seaclone skimmer pump and what a difference. Operates silently now too!
I have previously done all the mods to the seaclone and it was still poor at best. This is the mod that everyone needs to know about.
Maybe I'm the only one who didn't know about this...but I say good work Clinton.
I knew I would find a use for those bioballs from my wet/dry days.

Just a note on the Bioball impeller mod.
My bioballs must be a different brand than yours. Mine are the large size "Lee's" brand. They have 6 rows of pins, whereas it looks like yours has only four rows. I initially cut the last two rows off my bioball leaving three as shown in yours. Just for the heck of it I made another one and left 4 rows of pins. It now is just slightly wider in diameter than the original impeller. It works even better. I cut every second pin off on the outside row, but I only did that because I accidentally broke one off and wanted it to be somewhat ballanced.
Just thought I'd let ya know.

I was thinking about trying to use a coil on the impeller.
Ever use one of those milk frothers? Those things really work at mixing it up!
Figured it would be worth trying out.

hi clinton, i've made my own needle wheel using a bioball and notice that the pump loses its power gradually over a no. of days.....did u face the same problem?
i'm thinking, since the venturi that is made already produce pretty fine bubbles(by looking at a normal venturi skimmer), by chopping it with a normal impeller should be sufficient, perhaps a 6blade impeller or even better a 8blade one...are there any drawbacks? i heard its gonna be noisy....

Never had the lose of power, it is less powerful witht the needle wheel impeller but it's more efficent and way quiter. The 6-8 blade impeller woud work fine i would think but it will be noisey. Buy the way you really don't need a lot of power just the ultra fine bubbles. I've also found with less output you get a better foam production. You could try the extra impellr blades and slice them a few times to act like a neddle impeller.
