The selonoid will allow you to automate it, so that it comes on and goes off with your lights. Without that, you'll have to leave it on 24/7, which just wastes CO2. YOu can get a regulator with selonoid, bubble counter and needle valve for $78 on ebay. Search for the milwaukee MA957.

YOu can do diffusion with your powerhead whichever way you decide to go.

If you have a power head for diffusion, you are probably in good shape. You most likely will want to turn off the co2 at night and can do that with the valve. It may be a bit tough getting the flow right every day when you turn the co2 back on, but if you are just bubbling the co2 into the power head you can count your bubbles right there.

Give it a try and see how you like it. My guess is that you will be scraping the $80.00 to buy the reg, needle valve, bubble counter, and solenoid combo on ebay soon.

Enjoy!

Yeah, you can use the needle valve to shut it off each night. You'll just have to adjust it each morning before the lights come on, and try to keep it at the right rate. Selonoids take the guess work out of the flow rate for you, but either way will work just fine.

CHeck your local welding shops, roberts oxygen, places like that for a tank. 5lb tank runs about $70 I believe

I've also found out that CO2 tanks are used in home brewing so if you've got a brewing supply store locally it might be worth taking a look there too.
