14pp with diy co2 all night, too high ?

[Aquafamily]

We have a moderately plated fresh 55 and have been running a diy 1 2 liter bottle with airstone bubbling up to return flow on filter
i tested this Am and seem to have close to 13pp of co2, is this because i left it on all night with the lights of course and the plants now need to use it up during the day.

Should i turn it off, or take out the airstone at night now that the co2 has built up

Several folks said it would never come up to 10pp or over, maybe because:hi: im not planted fully yet ?

what PP # is dangerous ?
my nitrates have been 10 not 20-30 ? so say that's bad ?
We love learning

With a 55gal it is difficult to have too much CO2 with a DIY set-up.

Aquafamily, How do you test for CO2? Give us your KH and pH and can tell you what your CO2 is. 14ppm is not high. Mine is with compressed CO2 is 36ppm..

This is true, nice to know the KH and PH. The KH will affect the amount of CO2 in your water, which will change the PH.

But if you only have a DIY, you will not be able to "control" it anyway.

My 2 tanks are on pressurize CO2 at about 25ppm.

ok, only testing Ph goes from 7.2 to 6.2 at times, no testing kh yet,

We test co2 and iron with a drop reagent testing method
we are going to set up 3- 2 liter bottles with a liquid bottle to catch " bad " gas and prevent the white film smile on the airstone, not exactly sure how to do the in between bottle of liquid but we're gonna try I guess a check valve in between the last co2 bottle and the liquid ( water) and then between the aquarium too, but at that point it should be all gas, am i making sense ?

If you have all you bottle "in-line" the pressure may make them explode. I would treat every bottle seperate.
