I'm switching my 75g over to a planted tank, I have a 4x54w T5 fixture. I'm wondering if I could get good results without pressurized CO2. I'd like to but I have to many projects going on. Also I know the generally canisters are recommended but I have 2 AC 500's laying around. I've figured out a way to make them quiet using a powerhead. If I kept the water level up would they work.

It's probably Impossible to use the full potential of the light without injecting CO2.

You can use the AC500s until they can't handle the tank anymore...ie: plant debris, bioload.

How much will I be looking at for a basic CO2 setup.

~$150-200 as a rough guess.

Ya, but if your injecting co2 all day then quit at night your ph is gonna bounce around. Or do I have some chemistry thing wrong.

Bubble count is very important. I myself use controllers on my tanks and my clients tanks. They are an excelent tool for co2 applications.

pH changes caused by CO2 do not harm fish.

See www.theplantedtankFAQ.com for more info.

I would switch out the tubing, but is the rest of it good.
