CPR Bacpac Upgrade

[dsb1829]

Just posting up a little note on improving the performance of the CPR Bacpac. I have been putting it off forever, but yesterday I finally pulled off the venturi and replaced the pump. I ran airline tubing through the bio chamber and up into the riser chamber where I put two 3" limewood airstones. I powered these with a dual tetra air pump (might work better with a deep water pump, but it is only under 6" of water).

It was amazing. There were so many bubbles that I had to raise the collector cup about half an inch over the waters surface. With the venturi the collector needed to be under the surface to work. I will see how this works in the long run, but for first impression I would say that this is an upgrade that is worth doing. It also makes for much quieter operation of the skimmer, a definite plus since this tank is in the step parents living room. Just FYI, your mileage may vary

I agree its definately a huge difference..I switched my pump on mine to a maxijet 900 also that helped out a lot..Iam gonna switch to a maxijet 1200 in a few days or so..When I get the 46 back up online...Doug did you ever read my reply to that B.A.R.E. post?

Yeah, that RO unit is still sitting in the closet. Bummer on the 46, I would definitely check it over before continued work.
