need to higher ph for snails.

[Juicebox]

I have 2 tanks, 5 and 14 gallons.

the 5 ph is around 7 - 7.2

the 14 is around 6.2 - 6.4

i have snails in both tanks,id like the ph to be around 7, i have mostly the same plants in both tanks,the same dirt and sand,the same terra cotta pots,no idea why i get the big ph difference, the 5 gallon has driftwood and the 14 gallon does not, im not sure if the driftwood is making the ph in my 5 gallon higher,or lowering it in my 14..

i dont want to buy ph altering products as i hear bad things about them not being permanent and spking your ph..

any tips,any suggestions,in an ideal world id like my ph to be 7 - 7.2 so i need like a full 1 change in my ph, without spending lots of cash on products every few weeks if possible

What' the ammonia level in the tank that's 6.2-6.4?

What's the water source? Tap? other? What all do you add to it now.

tap water,no ammonia in the tests i did,i only add stress coat plus.

Usually tannins in wood lower ph, so I would expect the one with the driftwood to have a lower ph than the one without it. Also ammonia can lower ph which is why I asked about that. I'm not really sure why the difference then to be honest.

To raise your ph you would buffer kh up with something like Alkaline Buffer (it's basically baking soda far as I can tell) and maybe add something like Equilibrium to increase gh.. those two together will raise ph.. but anytime you start messing with this stuff it gets tricky. You'd have to invest in a good drops kit for ph, gh and kh and experiment with these things in different quantities to get what you desire - in mixing/testing buckets AWAY from the fish and once you have it stable over several days then try to introduce your fish to it.. but to be honest.. if your fish are happy and healthy I really would not start messing with this... You could end up with a wreck on your hands, and it's going to be expensive for all that stuff.

I don't know much about snails but your bettas should be fine in the water they're in right now.
