I would have loved to buy a compressed bottle system but I had a budget.
When I researched this aquatic plant hobby there was conflicting opinion
regarding substrate heating. I figured it would be a lot harder to add
cables later so I chose them over high tech CO2. As for the R/O filter
I've had that for 10 years - used it with a salt water tank. My tap
water is on a softener (salt type) so I don't use straight tap water.
I hear what you're saying though - consistent CO2 = more stable
conditions. I've known that is a shortfall with my setup which is why I
change yeast mixture weekly. I guess I should start looking around for a
CO2 bottle and regulator. BTW, do you use a PH controller on your system
or is that just a luxury item?

Wow, 50% weekly water changes? I must have missed something somewhere -
I thought 20-25% per week was considered good. If the plants are
consuming the majority of the Nitrogen in the tank what are we
accomplishing by removing 50% of the water every week?
