There is this stuff I use for my PH I can't remember the name but it is a powder that comes in a clear bottle with a purple label. Add the recommended amount and that will bring and keep your tank at 8.3.
This is what is going on with your tank. Bunch of debris and die from the rock turned into amonia, then Nitrite and then Nitrate. Nitrogen Cycle. You have plenty of bacteria to make the conversion since your rocks didn't dry most of the bacteria stayed alive. That's why you are seeing 0 for Amonia and Nitrite The only way to get the Nitrate out is to make a water change. I bet your number for the Nitrate is actually higer than that because the algea feed off the Nitrate.
At this point your water doesn't look super bad.
I would recommend making two water change a week about 30% each time.
