… I´d be carefull, taking on O2 is one thing - getting rid of the CO2 in the blood the other, suffocation results also on the inability to get CO2 out of the blood…for details look here “Has their environment changed these fish in other ways?” in Martin´s article:

perhaps someone has trouble falling asleep... just read my following text a couple of times ... don´t forget the pillow...
I´m short on time, therefore please excuse my telegramm style... thanks.
I dont mean to influence, as you have the nicer tank, you obviously doing things right here...
I helped a boy setting up a 300liter tank, he has similar water than me, he uses no CO2 and HE is harvesting plants biweekly like cracy - however it´s certain plants that go well, others don´t ... so every tank has it´s own rules. If I stop CO2 my plants get a calcium layer on their leaves, which is very annoying, the plants take out the calcium to set free the CO2.
... following, just some perspectives of a very large community here in central Europe, that I have collected ... not my brains... but I followed it and worked great, ... so far. You probably know all this - so it´s considered as a contribution to this posting in general...
- amount of light is highly influencing the plants producing O2.
- max. CO2 content with no risk for fish is considered 20mg/Liter. Thats pretty strongly recommended (however no scientific proof).
- CO2-gas used with the main purpose of bringing down the ph-value, is NOT recommended. There are recommendations to look into other ways to influence waterchemistry...
- CO2 is used as a carbon source, which plants need to grow.
- Carbonate hardness and CO2 influence directly and mutual the ph-reading.
in the following link to Olaf Deters page, the first 3 online-calculators, show the correlation between KH (=carbonate hardness in German Degrees "d°") CO2 content (mg/Liter) and ph reading, just enter your values and click the "=" button:

The following are charts from JBL. You will notice, that the values online calculator/ JBL chart are not identical - JBL is even more on the moderate side... however, both give you ideas...
… sleep well, hehe…
