Do you guys use a powerhead in your planted tank?

I just put a powerhead (maxijet 1200) in my 75 gallon tank. I placed it low in the tank to keep the water moving. From what I've read, plants don't like a lot of water movement and water movement also causes the co2 to outgas. However, with no water motion I would think my fish are in jeapordy. Should I put the PH on a timer or is one MJ1200 in a 75 gallon planted tank fine?

I don't use one. My tank just has a normal sized HOB filter with a very small one (came with my 1g) on the other end. Started to notice my fish hung out on the side with the bigger filter so I stuck the small one on there. Now they inhabit the entire tank.

I use one. You need sufficient water movement, and some plants need that movement,not to mention, water quality depends on it and your filter will work better with that movement, at least that is the impression I am under. It was either that for my 90 gal, or I was going to get a second filter.

I use two, one is for CO2 mist and the other one is on the other side for water movement. I also have an eheim 2217 on my 75G

I'm a believer in water movement as well. I don't have any huge tanks anymore, but long, deep, or oddly shaped tanks benefit from the extra push. When I've neglected a tank I'll run one for a while near the bottom--it seems to help them recover faster to keep things stirred up a little.

I use a Maxijet 600 for water movement, for filtration and for CO2 mist. It seems that without good water circulation you can have stagnant areas with low or no CO2, and that's not good. But, it does increase the CO2 needed to maintain a set amount of CO2 ppm in the water. It appears that I need double or more the bubble rate with the powerhead than I needed without it.

I use just a cheapo Penguin powerhead on the back right corner. The return from my Fluval 404 is on the back left corner. My powerhead only does 185 gph or so, so not a high concentrated flow rate, but enough to keep things stirring slightly. I just make certain that I'm not agitating the water's surface too much to prevent CO2 from spilling out.

Thanks for the replies. Thats pretty much what I've been doing. I have two canister filters running and I stuck the mj1200 in the bottom left corner and removed the sprayer from the top to keep the water from agitating the top. This seems to do well in my tank, glad to see I'm not doing it wrong.

I use a marineland 1400 for diffusion.
