Dude am concerned you are sucking in co2 scrubber media in to your water. That is the only way. If you add the co2 scrubber media to the water it will spike the water ph. Check for that..thisnis bigger problem if true.And trust me. If the scrubber was online the ph will increase to 8.6 easy
Media should not touch water or get in your system.
If your suction is high it might suck in media or media powder and mix it with your water..
