Hi
I am looking to changing the tubing of my kh keeper because of algae growth in the lines
Does anyone know which one i should buy?


Thanks

Did you ever figure this out?

None of those will fit. Original Kh keeper tubing I believe is ….ID 1mm / OD 3 mm. Newer KH Keeper Plus tubing is ID 2mm / OD 5mm.
