I'm trying achieve a stable aquarium to keep some Eriocaulon and shrimp. The target number I want to hit are PH 6.2-6.5, KH 1-2, and GH 3. I'm using RO water in my tank with no CO2 added which gives a PH reading of 6.4, KH 0, and GH 0. I'm guessing with the addition of CO2 the PH will drop even lower, but I would like to raise the KH and GH. I know mixing in some tap water can help raise both, baking soda will raise KH, and GH can be raise with GH booster from what I learned, but are there anything else that would affect them? Such as shrimp/fish waste, decaying plant matter, EI dosing with the except of the GH booster (KNO3, KH2PO4, CSM+B, Fe). Also would adding baking soda affect PH/GH and would GH booster affect PH/KH? The GH booster I have on hand consists of three part KSO4, three part CaSO4, and one part MgSO4.
Thanks in advance.
