hi, do you know this product API Proper pH 6.5 - PH Buffer Adjuster Freshwater Aquarium Fish Tank Stabiliser | eBay ?

my ph raise from 5.8 to 8.0 every couple of hours. how can i solve it? why does it happen?

My PH from the tap is 7 so I have never used that product. You can use Baking soda to raise or lemon juice to lower PH. Add a little a time ad retest. Wait for a few minutes before using. I have had it change quite a bit in a couple minutes. Hope this helps.
