To lower Ph there are several things you can do. First read this webpage there is info on it on ways to lower PH
If you have a friend that has a water softener, Ask to borrow a couple gallons and swap out some water, but not all of it. Check the PH of the softened water before you add it. This is not a long time solution unless you have a very good friend.
Add some dirt. It says in the article to filter through Peet. This may not be avaliable but you should be able to find some at a good gardening store. Make sure it has no added fertalizer.
You can put the peet in a small micron bag like this one

Hang it in the tank where there is good water flow. Check the parameters often. This will suck up PH like a sponge and you do not want it to drop too far.
Your PH is not that bad. My tanks are generally at 8+ and I do not seem to have too many problems. I have guppies out my ears and apple snails seem to be doing fine.
Get a good test kit first. Buy them online you will save a bundle. 25-40%
