Bargain Co2 Units!

kh = 6

How does that work?

You need 11.5 bubbles per minute,
Thats 1.9 per second, lets say 2 per second.

Handy thing the PFK website, its got loads of usfull calculators.

You thought i was really clever didnt you

So according to their calculator more KH needs more CO2 output to reach the required level.

Can anyone explain the science behind this?

I assumed no matter the KH, an identical bubble rate would give identical CO2?

Thought you must be clever! Dont you mean 115 bubbles per min not 11.5?

haha got ya!

I was on the PFK website before but could'nt find that calculator.

Mantis, you may need to login/regitser but its in the calculators at the very bottom.

gf, was wondering the same thing, how do thay do the maths?
But what level of CO2 is in thier opinion the requierd level

I will have a look! Cheers!

If the calculator sais 11.5 bubbles per minute thats roughly 1 bubble every 5 seconds isnt it?

Im a bit confused here as well, although its late and im tired, i will think about this and get back to it.

One thing i do know is that if i added the recommended 9.5 bubbles per minute on my 42 US gallon tank with a KH of 3........it would be a mess within a day or two, they are not aiming for 30ppm CO2 with these calculations although they dont exactly say what level they are aiming for unless im missing that as well.

My thoughts exactly!
