K2SO4 addition + equilibrium?

I am using the EI and have a question about dosing potassium.I usually dose my high light/co2 55 gal. with 1/2 tsp. KNO3,1/8 tsp. KH2PO4, and 1/8 tsp. K2SO4 every other day and 10 mls. CSB+B on the off days. My question is I usually add kent's gh+ during water changes to up my gh to about 6, now I'm going to try using seachem equilibrium.The equilibrium will add about 80 ppm of potassium, according to the bottle, so should I still add the K2SO4? I would think that it is not needed at water change because of the ample ammount in the equilibrium. But what about the other days when I add macros, should I dose potassium then?The tank is heavilly planted with alot of stem plants, over 4 wpg and pressurized co2. I would appreciate any ideas and suggestions. Thanks,

The suggested potassium level is 20 ppm. So if product A is giving you 80 ppm there is NO need to add more K.
