Tums for snails?

I've just been giving him snail jello, I got two more mysteries to put in there, they don't seem to care for the jello though, what flavors are popular for them? I tried an all vegetable one and only one likes it.
Strawberry
Orange
Lemon
Lime

That's the order. The top one is their most favorite, at least in my experience.:)
 
My ph is not as high as it needs to be. I start with around 7.6 after a water change and for a while I had a problem with it slowly going down to around 6.8

It's a little bit more stable since I put some cuttlebone in there. It gets to around 7 just before a water change, so I guess I'm asking if the Tums will help keep the ph up?

Also, let's say I have a slight spike of nitrites, will Tums make the situation worse, or have no effect?
whats your tap water readings? how hard is the water? there are better ways to get calcium into the water. more so if your going to keep fish in there at some point in time.
