Just bought a pH pen/tester and tested the tap water.......8.3.....quite high I thought.....
Anyone tell me what can I use to get it down? Do I have to buy the 'pH down' stuff or is there another way?
With nutes in and stood for about 12 hours it was 7.4. But if I leave it to stand the oxygen will be lost, no?
I'm not buying a pump.
