Looking for something just to shoot the Co 2 bubbles across my tank obviousely looking for the least conspicuous with flow that won't uproot my plants. Post which powerhead you are using for this application & give pros & cons.
Particularly interested to hear about the eheim ball......Anybody ??

The only powerheads I use are Koralias. They push so much water for the money.

are you looking for something to chop up the bubbles or just circulate them around the tank?

The bubbles are fairly fine I really want to get em" across the tank before they surface.
I have multiple sources of Co2 going into the tank so I can sacrifice a little efficiency for asthetics....efficient & asthetic is what I'm looking for.
I did look @ a hydor nano Koralias in the LFS tonight as it happens & I liked the look of it. Also @ 240G PH it may do the trick I did not notice the mag mount on it, were there some older models w/out mag mount or did they all come through with that feature ??

How big is your tank?

Koralias have really high flow rates but the way the flow is produced more of a current than a concentrated stream that most powerheads produce. If I were you, check your LFS's return policy before buying it. You may end up wanting the next size up.

I believe all Koralias have always had a mag mount. It's actually kind of a combo. Part mag, part suction cup.

Have a 120 gal w/2 2028's one has a Diy reactor @ the other end of the tank I have a diffuser infront of the pump outlet and 2 sweetwater airstones spaced thru the center of the tank. I have lots of Co2 going in but I wanted to slow it's rise 2 the surface by shooting it across the bottom of the tank. It does'nt have to shoot it from one end to the other becuse I have Co2 sources spaced across the tank. Had been looking @ the Koralias #1 @ 400GPH & the #2 @ 600GPH Also.
