Perfect fit By Laredo300c on 6/18/2014Laredo300c would recommend this product to a friendWell i ordered this kit as i was reaching my first year with my ro/di unit. I only mix 15 gallons a week. Filter kit arrived super fast and was a breeze to install. Of course when i was ready, i couldnt find my canister wrench, so one quick order and my wrench was on its way. Took 10 minutes tops and make sure you flush pout the unit.

I ordered a 4 stage replacement filter kit and got the bag of stuff. Where does it go? I dont have a cartridge that opens and lets me fill it with anything
Bulk Reef Supply Hi Joe,
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.

Will these cartridges work to replace filters on a Coralife Pure-flo II 50 gpd system?
Bulk Reef Supply Hey Brad,
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).

I upgraded my 75 GPD RO/DI unit to 150GPD. I recently purchased replacement filters due to seeing green algae inside the filters and housings. I changed out and rinsed out as much as I could when changing filters and DI resin. However, I am seeing more algae starting to show again. I took ALL filters out and ran some clorox water thru the system, then flushed it with clean clear water. My system is located under a deck outside my laundry room. It gets no direct sun. What can I do to stop the algae? Should I drain the filter canisters when not using it? I ran clorox thru since I figured the 1/4 tubing maybe have algae contamination.
Bulk Reef Supply Hi Jeffrey,
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 :)
