I'm sorry if the topic had been discussed before. However i can't seem to find any exact answer regarding my question. The tap water in my area isn't that good, so i've been using RO water mixed with mineral water (its kind of cheap here). I've been thinking of using RO water and remineral the with seachem equilibrium. Is it enough or should i add any additives, i know that it would raise gH to a desired level, but would it raise enough kH? Thanks!
I saw some videos and read a few forum that they remineralize their water solely using seachem equilibrium. Would only using equilibrium cause pH swing(due to the low kH)? how much should i add arm and hammer baking soda for every 10l of RO/DI water?
Thanks!
I can't seem to find anyone that sells KHCO3 that is accessible from where i am, is it alright if i use K2CO3 instead of KHCO3, or would the plants and livestocks suffer from the excess K? Thanks for the replies
Sorry for the late reply, so let's say I'm going to use equilibrium to increase the GH to 5 dH use K2CO3 to increase my kH, and aims for 1dKH and pH between 6.5-7.2, how much should i add K2CO3 to each gallon of water?
If i replace K2CO3/KHCO3 with NaHCO3, would the Na somehow cause any harm to the plants or fishes?
And is there any calculator/formula that i can use to calculate how much should i dose to reach my aim?

Try and look for CaSO4 from a brewing supply store, it's a very fine powder and dissolves relatively easily.
I was always using KHCO3 from a brewing supply store. very fine granules, CaSO4 from a brewing supply store, very fine powder and MgSO4 generic drug store brand that resembled course ground salt you put on a steak.
I mixed them up a day ahead, or at least the morning ahead of a water change, and would bring the remineralized new water up to the tank temp before performing a water change.
I know this is an old thread and a very late reply. However, the only CaSO4 available from where I live is CaSO4 Food Grade, I don't know whether it is CaSO4.2H2O, CaSO4.1/2H2O, or CaSO4(anhydrous). I checked the manufacturer's website (apparently it is an imported good) and the only information regarding the product is that it is food grade, 92-99 purity, and the molecular formula is CaSO4 (checked the other product from the same manufacturer, both anhydrous, dehydrate, and hemihydrate has the same formula CaSO4). I wonder if you guys would know wether "food grade" is anhydrous, hemihydrate, or dihydrate? also, both Zorfox Planted Tank Calculator & RotalaButterfly Calculator only has CaSO4.2H2O and CaSO4.1/2H2O option, no anhydrous option.
Is there any way to distinguish between CaSO4.1/2H2O, CaSO4.2H2O and Anhydrous CaSO4?
Would using CaSO4.1/2H2O calculation on 2H2O/anhydrous and vice versa would bring enough difference in calcium and GH to be any harm? Thanks!
