CO2 question

[Nik_boyd]

I've recently purchased a C02 system for my 50g tank, and included with it was a permanent Co2/PH kit. Now, I love German made equipment, as with all German equipment it seems very solidly built. But can they translate a manual (properly, in clear English) or provide much information? not a chance.

In the manual it says to start with 1 bubble in every other chamber of the diffuser (a JBL diffuser column if anyone is familiar with them...) and increase gradually over a number of days. I kept it like that for a few days, but the permanent Co2 test is registering a PH of 6.4, and that Co2 content is too high. I've now turned the Co2 down, to about 1 bubble in every 4 chambers. I've done a seperate liquid (Hagen) PH test, and it still shows up as the normal 7.4 None of my fish are showing distress, but I was hoping that someone could shed some light as to why the permanent test registers so differently, and is this a problem, have I added too much Co2?

thanks people!

Does it give a value for the CO2 or just too high? Anything above 30ppm will be dangerous to the fish and you will see signs. It sounds like your system is a trial and error thing. Once you get it, it should be fine. I am not familiar with that particular brand of CO2 injection but someone else may be able to help you that does

good luck

30ppm is not dangerous - Its ideal for a well planted tank.

we ran our planted tank at about 30ppm for months without a problem. (we moved recently and its been replaced)
9ºKH and PH at about 7.0
