Yeah !! Maybe your old rocks where changing water chemistry (increasing KH value) then stabilising PH if your tap is low KH

Why add salt ? Don't add salt

If you want make your aquarium brackish at 0.1 or 0.2% salt, it will be bad for your plants (I experimented it), and you will have to check on the web the salt tolerance of all your fish kinds...


I'm searching for you the amount of sodium bicarbonate to add to your tank to raise KH value by 1 dKHį

You have 15 gallons right ?

I think 6.5 can be fine. One thing to not do is add one shot too much of baking soda, the ph change will be violent stress on the fish and can result dies

According to this website, for a 14 US gallons tank, to raise by 2 dKHį, you should add 2.645 grams of sodium bicarbonate... : CNYKOI - Alkalinity (KH) calculator

But don't add all this ONE SHOT, it can stress the fish.

Raise the kh slowly, the PH should follow later. Don't put baking soda and test 1 min after. Wait a good 5-6 hrs

This is exactly 2.5 gramms of Arm & Hammer

1 teaspoon = 5 grams of baking powder

So start by adding 1/2 teaspoon, and wait to see what it do to the ph after 1 day... Add another 1/2 teaspoon if not happy with the PH, and repeat until you get what you want, but seriously, dont add 3 teaspoon one shot, it will be violent on a 15 gallon tank

It's highly soluble... I would put it direct into water in small doses. You can find it in any grocery.

It's probably coming from dechlorination. Chrorine is very high ph, so if your tap is 7.0, 7.5 with chlorine and your remove it while your KH is low, the PH may drop.

You will have to add half (or less?) a teaspoon each water change. There's a thing that can interest you, it's your tap kh value. Make sure you add Arm&Hammer in your water bucket before you put it in your aquarium, violent PH changes stress and may kill fish.

In my case, my tap is at 2 dKHį (approx 35ppm carbonated hardness), and I don't have ph drops problems.

KH is a PH buffer.
