I was thinking that was quite a bit of baking soda then I got to the 40 dkh reading. I wouldn't change it but I'd allow it to fall over time to the 20's

You can cut way back on the baking soda and still get an 8.2 or 8.3 pH. That's where it'll max out, so adding more does little for you. A KH of 8-10 would be fine, so I'd cut it back to 2.5 tsp. Your GH is even a bit over what it really needs to be. Low to mid teens is high enough.

Just curious about the parameters of your tap water. What are you starting with?

I have tap water that's similar. I add 1 TBSP (3 tsp) per 25 gallons of both sodium bicarb and epsom salt and it brings each into the teens. You're adding equivalent of 2 TBSP per 5 gallons or 10 TBSP per 25 gallons, so you're adding about 10 times what I do.

Try adding 1 tsp to 5 gallons along with 1 tsp of epsom salt and let it sit overnight before testing. Aerate it if you can.

Per 5 gallons all you need to add is:
1 teaspoon of Bi-carb
1 teaspoon of salt
1 Tablespoon of epsom salts

Your adding way to much which is doing nothing but complexing your water

Add this amount to the water you add during water changes. If you add 5g of water add the recipe given, if you add 10g double the recipe eg: 2 teaspoons bi-carb
2 teaspoons salt
2 tablespoons epsom

Try adding the above recipe to 5 gallons of your tap water. Your hardness should be ok but if your ph is still low then add another teaspoon of bi-carb only, this should be plenty to raise your ph. to 8.2

Your ph. won't go any higher then that using this recipe
