1) I don't understand why it is necessary to dose with K2SO4 if Potassium is supplied with both KNO3 and K2HPO4...
2) I haven't noted any posts on this thread about testing. What testing besides CO2 is being done with the PPS pro system?
3) What test kits are recommended? There seem to be so many but I would like to have some kind of review or critique of the test kits for nitrate and Phosphate, and the pH paper that is best for aquariums.
4) Although there is a lot of cross talk about water changes, what percent change and how often are changes necessary or desirable when using PPS pro system?

Thanks for your comments which are greatly appreciated!
