How much bubbles/per sec is require for a 90g tank?

[andyl9063]

Is it just the 1 bps standard for every tank? I don't think that make sense.

Is it a case by case where you just have to test it out and see how much works? I search and some of the info was conflicting.

Andy,

Go and buy a continue Co2 test.
That is the best way to get you Co2 right.

 

[andyl9063]

I have never heard of a continue co2 test, what does it do?

 

[dbazuin]

The good ones come with a special calibrated test liquid.
The level of Co2 in the water en in the test will be the same after a hour or two.
The liquid wil change color and the chart with will give you a reading.

Bubble counts will differ depending on the equipment the CO2 is running through. Get two drop checkers. http://www.barrreport.com/showthrea...wo-are-better.-(or-wet-killed-a-bunch-of-fish.)

This might be a little off topic, but about what psi is going through the line typically for a 20-30 gallon tank? I'm thinking around 8psi.
