I change the water every week.Plants but no rocks.

checkout my sig and click the link for water on ways of naturally lowering the pH.

I'd be more concerned with your NO2 (nitrIte) levels than the pH right now.

you need to get something that will help with you NO2, look for bactinettes (natural bacteria; the best), bacterlife by Waterlife products(not as good), toxivec by Sera (a chemical that bonds NO2 but dosent destroy it) or a similar product.
Also a few regular water changes over the next 5 days will help if you can't get/afford the above mentioned.
