I just got my replacement filter for my Ocean Reef +1 yesterday.
I remember reading some where how to replace them. I think it said to sanitize the housing with bleach, etc..
Do you have a link to the steps?

Turn off the water supply to the system.

Remove all housings and remove all pre-filters and post-filters from the system including sediment filters, carbon filters, in-line filters, and deionization cartridges. Remove the reverse osmosis membrane(s) as chlorine will destroy it.

Wash housings with a soft brush or cloth in warm soapy water. Rinse thoroughly to remove all soap. Fill each vertical housing with one cup of potable water and one tablespoon of regular strength unscented household bleach, and with this sanitizing liquid still in the housings, screw them back on to the system.

Turn on the water supply a bit, allow water to fill the entire system, and assure water is flowing out of the waste line and the purified water line. Place the outlet of the drain tube and purified water tube slightly higher than the system to assure these tubes are full of the sanitizing solution. When the sanitizing solution has reached the outlet of each tube, and with the outlet of each tube placed above the rest of the system, shut off the water supply for 30 minutes.

After 30 minutes, turn the water supply on and assure that water exits the system from both the drain tube and the purified water port. Flush the sanitizing solution from the system for 5 to 10 minutes.

Turn off the water supply and install new filters, taking care to flush the filters as appropriate.
