Sure, I use both KNO3 (for my nitrates) and K2SO4 (for the K). No way I could use enough KNO3 to get the right amount of K without getting too much NO3 as it seems my tap water is lacking K.
For my 90gal I use 1tsp K2SO4 on the weekly water change and 1/2tsp in the two fertilizations between weekly water changes with no problems (1/2tsp, 1/4tsp for the KNO3). If you only change the water monthly maybe just use the lower mid week doses. Personally I find water changes with the python so easy I just do it weekly instead of trying to keep track of the fert levels, spend time changing water or spend time testing fert levels ;)
