RO water with high PH? (new to RO)
Setting up a small shrimp tank and we decided to use RO water from WallyWorld (cheap). We added Kent Liquid R/O Right when we set up the tank. Tested the water after the tank running for a few days, and the PH is between 7.4 and 7.8 on a high range test! We left some to sit for 24 hours out of the bottle, and it tests the same! Yes we checked the label - it's RO, not spring water. KH and GH are zero as expected.
Shouldn't RO be neutral or slightly acidic? How can we get the PH down? This is a tiny (5.5G) , non-co2 tank.
