The turboflaater is Ventrui with a Needle wheel pump I believe.

Ok well lets have an idea to modify the one i have and pump i have.

Ok if I do this how will i stop the bubbles from going out the output?

What pump are you running, are you still trying this on a mag18?

I run a mag18 on my PM-1 bullet skimmer and it's a good combo. On my SPS tank (which is fed somewhat heavily) I pull out 2l of black-coffee consistency skimmate per week.

The PM-1 is a considerably smaller skimmer than what you're trying to run here.

I'm sorry but I think you need to make a decision, that skimmer has to go much much smaller, or you need a much much bigger pump. If you look at any of the larger beckett style skimmers, the usual recommendation is to go with at LEAST an Iwaki 70 or two Iwaki 70's, or an Iwaki 100. If you look at the specs for these pumps you are going to realize that this is a very expensive proposition. They use a lot of juice out of the wall.

If it was me, and this is just my opinion, but I'd step up to a Mak4 pump, and make the skimmer reaction chamber and injection tower no more than, say, 24" to 28" tall. Anything more than that and you are going to require multiple injectors and a stronger pump.

Ok well before i cut down even further or upgrade to a mak 4 ill try releaving the pressure. Ive removed the 90 degree turns and put in some baffles i guess ill test that out then maybe go for a mak pump. How would i go about attaching a mak pump with no wholes in the sump.

If it was me I'd just pop a hole in the sump wall, but if you'd prefer not to do that, you could build an "up and over" thing with PVC. Just put in a T somewhere, with a union to a capped pipe, so that you can pour water into the pipe for priming.

You'd have to do a U-tube over the edge of the tank into your pump.

Dang! Tony's too fast!

Can you add a needle wheel to that Mag 18 you have??

relieving pressure
 

no matter what turns you take out will not negate the water pressure in the chamber. if you want an idea to what you have setup, then cut your main chamber down to 6-8 inches high so its similar to Delphinus's bullet 1. a mag 18 is not even pressure rated so its only moving water through the beckett; it should be pushing water through the beckett to create bubbles. in comparison, you are trying to tow a tow truck with a Chevy Sprint - the tow truck will move .... very slowly and the Chevy Sprint is not going to be sprinting anywhere fast. You may even wear down your impeller on your mag 18 if there is too much back pressure on your mag.

Just like you've stated in the topic of this trend, a mag 18 is not big enough for the monster skimmer. If you want to keep the mag 18 and you want a skimmer, take out the monster.

Ok well ill test my new system with my mag 18, if it doesnt work i will upgrade to a mak 4. Now with this said will a mak 4 be a good enough pump. The only thing chin-lee is that its making tons of good bubbles there just not making it around to the reaction tube.
