Hello Seanec sounds like you got a bit of confusion there I take it your testing your water with a test kit what make/name are you using?
I use the Api master fresh water test kit that has the option to test high PH and PH I have found that with my local water that is HIGH around 8.0 so I do not use the PH testing as it always MAX's out so I use the HIGH PH test to give me a reading.
I do hope this helps you

Ph 7 as in a ph adjuster? Don't use it, it won't give you accurate readings and it is a waste of time. It will only flucuate which is bad. Is some coral sand in the filter to raise the ph
Don't use it, it's a waste of money, place a handful of coral sand In a filter sock and pit it on your filter.
