I use Coral gravel and keep a few bits of large Coral it seems to keep ph around 8+
and about every 2-3 weeks with my water changes add some Cichlid Lake salt by Seachem and seems to keep ph stable .Maybe give this a try,but start off adding your salt a little at a time and build up dosage with water changes :thumb:
