Here we go again, some one wants to suggest the NH4 is helping, well, add some NH4 if you feel that sure. Newbies and folks that are not careful, don't bother, you'll kill off all your fish and have a nasty algae bloom. I have tanks without fish to do stuff like this.
RO water change still have a fair amount of CO2, even if it's removed fast, it still gives a nice boost, but that's not the 1/2 of it nor the significant part.
When you do a large water change, do the plants get exposed to the air or not? How do you think that effects the plants in terms of CO2 if they are limited prior?
