Powerhead.. Help

[CBBP]

Yes Hi.. I need a powerhead with these qualities.

Submersible
Has self Air Intake tube
Easily connected to gravel vac tubing.
175 GPH

My plan is to have the co2 pumping in at night and the air line closed and then reversed at night. This o2 diffused in at night and co2 diffused in during the day.

You seem a little mixed up there!

"My plan is to have the co2 pumping in at night and the air line closed and then reversed at night."

Co2 normaly goes in during the day and OFF at night, i have only just learnt thats its fine ON all of the time.
Providing you have good plant grwoth.

The idea sound like a good'n though, perhaps in the reactor you could add some bio media to help break up the bubbles and add a little extra filtration, or some very wide gage sponge for the Co2 to be blown through.
