Does anyone know the size of the ORings in the ReefOcto Cal React 220 ?
Just bought a second hand unit and it seems to be sucking in air wanted to replace them to rule of seal failure
Ideally I will replace them all understand the one in the ph probe spot is also a serial lead offender
Thanks so much for any help
