I don't think you need to change the pH at all.

What about ammonia, nitrite and nitrate levels?

P.T.

the lps told me to only worries about the ph levels...so thats the only test kit i bought....

You should tell your lps other wise! Ammonia is the first test kit to get, than nitrite being a close second. These two can be more toxic than pH and can suffocate a fish within days. These products come from a build up in fish urine and poo along with anywaste(decaying plants and leftover food). If these waste are left to spoil, your ammonia and nitrite levels rise poisoning your fish. Here's a full article on theNitrogen Cycle to help you understand better.
