there is another solution have you ever thought of snail eating snails i found these at my local aqurists they are only a couple of pound or in dollars about 3 dollars so its not to bad but in my opinion i never thought botias would raise ph levels eating snails but try and find them snail eating ...

try adding some coral grit to your tank it will help with ph i use it and its fine it never goes up or down stays at a constant level unless you do a part water change then it goes up slightly you only need a couple hand fulls and thats it i hope this helps
