[e46er]

90 days then replacing the disk? seems expensive.
I wonder if you could plug it in a controller port or manually remove it and just test once or twice a day instead of every 15 minutes I don't need 96 tests a day. I bet most peoples tanks don't get 96 tests a year! unless of course just the exposure to saltwater is what takes the life away from the disk.


anyone know what a disk cost and are they all individual or just a single disk?
Im fairly interested in this product based on the answers to the above questions.
