Exclamation RODI Water & only buffering with CAS04

Hi guys right now I buffer my 100% rodi water with equilibrium & alk buffer & acid buffer to get the PH GH KH values I want
GH 6/7
KH 4
PH 6.7
Im starting PPS Pro & according to GLA web sight I will only need to add CAS04 Calcuim Suffate to my new rodi water PPS will have every thing else the water table needs when dosing ferts.

So if this is correct will my KH GH Ph values matter or be harmed ?

Not quite exactly sure why you are using 100% RODI water and then buffering it back up. Is there something drastically wrong with your tap water and/or mixing tap water with RODI water?

It seems wasteful to use 100% RODI water, only to buffer it back up to water with conditions similar to what might come out of a tap.

As for your question, adding calcium sulfate (CaSO4) will raise your GH slightly (depending on how much you add).

My tap water is terrible thats why I don't mix. So do I understand GLA correctly that other than dosing with PPS pro, I would only buffer new rodi with CaS04 and my water parameters would be ok ? Just seems like soothing is missing , don't want to accidentally kill the angle fish.
Thanks for helping a beginner on a steep learning curve.

pps pro is a maintenance fertilization solution. Its not meant to total reconstitute ro/di water. It might get there eventually depending on the uptake of nutrients from the plants but initially its way to light on the calcium, magnesium, and potassium.

I also use ro water then reconstitute. I use KSO4, CaSo4, and MgSO4 to raise the GH and some baking soda to raise the KH. With what I dose for my 60 gal I have 1.5 KH and 2.5 GH.
