So I have been mostly focusing on the nitrate, nitrite, and ammonia in my tank to ensure everything is as it should be, but I recently got test strips for pH, GH and KH as well, and noticed that my pH and KH are way too high due to my tap water. I've been battling with lowering the pH for a while but nothing helped so far (adding wood, tanning from Indian almond leaves, and I have stratum substrate which is supposed to lower pH).
What is the best way to lower those in a heavily planted tank?
