will this co2 set up work for aquariums

Did you ever try growing tomatoes on a hoizontal trellis to maximize overhead light exposure? Just something I'm thinking of trying.

I fixed the photo i think.No i haven't attempt what you speak of but would give it a shot...

No it won't work. For aquarium use you need extremely low flow rates, much lower than that device can give you. That's why a regulator and needle valve are needed, and why the flowmeter is useless for an aquarium setup.

thank you...

Hydroponic tomatoes..... sure. Everybody loves tomatoes..... lol. Glad you asked this question as I was wondering the same thing.

i see alot of these regulators on CL here in the SF bay area
and i have always wanted to know if they would work
