I have started using this humic acid additive and i noticed after the first watering my resi rises in PH from 5.8 to like 6.3-4..Only in first watering after resetting the tank...then i reset and it hovers 5.8 and down like lately..
So question is??
Is it possible for the H-2 to get "stuck" in the RW slab and not return to the tank like the rest? That would eliminate a bunch of acid nutes and make reason for this..
Wondering if anybody has the same experience??
