Instructions
Test the pH of your aquarium water and the RO water. Note the results.
Remove 5 percent of the water from your aquarium and refill with RO water. Test the water after 10 minutes and note the result.
Perform small water changes with RO water until your pH has lowered by 0.1. Take a note of how much water needed to be replaced with RO.
Repeat Steps 2 and 3 every 48 hours until your desired pH is reached. Ensure pH only lowers by 0.1 each time.
