While I will say there is a large element of subjectivity, I'm not sure the fish welfare argument isn't a straw man fallacy. In the case of the guppy, the level of SAFETY is 1/10 the ld50. ...

Biological activity (rotting detritus) is going to reduce alkilinity and pH not reduce it. I'd also suggest that unless you are seeing a shift in tank water pH, the substrate pH in unlikely to have...

As far as flow, its going to be heavily dependent on the type of fish you keep. Angelfish, discus etc aren't built for high flow. I'd be willing to say there is going to a limit for any fish that...

Could be a CO2 buildup helping (at least partially), but I'd be willing to bet same thing would happen without the CO2 on. Pearling is highly dependent on flow and O2 saturation, without the filter...

The relationship between pH and CO2 content is logarithmic not direct. One iteration of the calculation from which the CO2 tables are derived is CO2(in ppm)= 3*dkH*10^(7-pH). ...

As someone's already pointed out, it's not going to work as a preservative unless it incorporates some level of toxicity. All about dosage.
