Just Bought A Co2 System

[Gordon88]

Ok the i have 190l tank and i am having the CO2 on a timer from 8 in the mornin till 8 in the evenin. The low pressure gauge on the system is measuring in PSI and BARS. I need help knowing how much to put in my tank.
I want to put about 25ppm in but wat is that on my gauge? as i do not want to kill my fish!!!
Thanks
Any help will be appreciated

Start off at a bubble per second and take it from there. If your CO2 level is too high/low turn it down/up. MY JBL has a pemenant PH/CO2 indicator which gives an indication.

Thanks achown, anyone else have any recommendations??
Achown how much did ur pH controller cost u??

Its not a PH controller-it's just a permenant test kit. This one
.Personally I find it awkward to read and use test kits to measure my KH and PH and work out CO2 from there.

Thanks alot been great help, i will just keep testing the pH and KH then.
Thanks

Yeh as Alan said you don't work out the CO2 added to the tank based on the gauges on the regulator, you added a certain number of bubbles per second or per minute (these work out the same its just two ways of expressing the same thing, bubbles per minute is easier to work out on bigger tanks that need lots of CO2). For you're tank I reckon you'll need around 2 bubbles per second. So start with that and up/down it accordingly.

I wouldn't try getting exactly 25ppm as the test kits aren't that accurate, so if you're getting between 25-35 I would leave it at that. Also, I tend to have mine running slightly higher than necessary just to make sure. As long as the fish are happy IMO its better to have to much than not enough.
