how long will it last???

[abrahamavelar]

ive been looking for a pressurize co2 so i was wondering if i buy this:

Aquarium CO2 Regulator SET- Diffuser Bubble Counter ph | eBay

or this:

Aquarium CO2 Solenoid Regulator Bubble Counter Built-in Check Valve DC02-04-BLUE | eBay

the second being the best option, even tho the 1st its alot cheaper i think the second one will be better, anyways my question is how much will a co2 20 oz tank will last???

i have a few 20 onces co2 tanks for a paintball gun i used to have and i was planning on using.

so once again how long will it last on a 75 gallon aquarion tank???

You might get more responses if this were on the planted tank section...

I would estimate... about two weeks.
