It increased about 0.2.

Given that I have about 700 gal of total water volume, and I added about 150lbs of play sand ($7.50+tax), it's not a big increase.

The best part about play sand from Home Depot is that it's washed and seem pretty inert! I just opened the bag and dumped it into the tank.

Hey when adding the sand, is there any PH swings?
