Do you have to match the PH of the freshwater dip to the tank water. My RO water is 7.4 or less PH and my tank is close or at 8. I tried putting a splash of tank saltwater in to help buffer, but it didn’t raise the ph at all. I’ve read some other people suggest using baking soda to bring up the PH? Is that advisable? Or is fine for the ph to be different? Sorry for all the questions today...My head is spinning trying to do something to help my little dude and not hurt him at the same time.
