Please fill out the troubleshooting form at the top of this section and post your answers here, but so far you have given enough info that I can assume you did not pre-stabilize the pH of your hydroton before use, hence the rise. You're going to need to keep on top of that until it stabilizes, checking at LEAST 2x/day and adjusting back to 6. Is that a flood n drain on a res?
