Hi guys I buy all my water premixed but today when I got it home I tested it as I always do before adding to my tank and it came up at 40ppt. I checked my tank and its sitting at 34.5.
I recalibrated my tester and got the same results. So I haven't added the water obviously. I have 3 x 5 gallon containers of the 40ppt.
I was wondering if anyone knows how much RO water I would need to bring 5 gallons of 40ppt down to 35ppt?
