CO2 is a little better, glad you have a good steady level. Replace it before it runs out - unstability in CO2 is also a big invitation to algae.

Low doses, because you're not high light and compressed CO2, are all that is needed for maximum plant growth even if your 20 is packed full of well-growing plants. And I'm glad to share whatever I have picked up in the last 14 months.
Again, thank you very much! I know the risks now, and have been paying extra attention to fish health, tank parameters, and algae growth. So far no change! The plants on the other hand are actually growing and looking healthier. This could be coincidence of course....
I change one bottle every week. So one bottle will run for two weeks total and then be replenished. Works for me.
And I'm gonna try lowering the dosage a little. See what happens. 'You are a scholar and a gentleman'
