Ask a question
Do you have our 4 stage RO/DI filter system? If so, the last stage to the right is the DI stage. When you remove that canister the bottom will screw off the cartridge inside of it allowing you to replace the resin.
Our filters are universal 10" filter sizes that will fit almost any unit on the market (including the Coralife). Keep in mind that we package our DI resin in vacuum sealed bags to be used with refillable cartridges. If your DI cartridge isn't refillable youll want to pick up a refillable one the first time as well (sku 200002).
Even though your system may not be getting direct sun it is still receiving enough light to support algae. I would place it in a cabinet or cover the canisters to completely shield it from the sun. This should be enough to prevent algae growth.
Running bleach through the system should kill any algae spores but it will also damage your RO membranes and quickly exhaust your carbon filters which are now likely contaminated with algae. Its also possible that your tap water contains enough algae to contaminate your system so this could be a never ending battle in your current situation.
Before running any more bleach through the system I would try the first solution and go from there.
I hope this helps!
Have a great day :)
