Question: does the resin come in a sealed package?
Document: The product is excellent but in he sent the bag I come it rotates and it got lost a bit of the product in the box but I come in time they must be mas hanging when they do the crate of the goods thank you
This resin reduces the cost per cartridge down to about $7.00 each vs a new one each change. It adds up when making 90 GPD
I bought a refillable DI resign water filter and installed in on the RO water line to the ice maker.Easy to replace the old resin and refill from resealable bag
But I would suggest a bag a little more substantial than a standard zip lock bag. Even if you used a freezer grade Ziploc, that would be better. I had to store the surplus resin in a beefier bag. The Ziploc it was sent in was almost to the point of giving out. Wow, that would be a HUGE mess!
I am returning this to the vendor due to an unpleasant taste. From conversations with the seller, I understand that non-color changing, nuclear grade resin would be better. However, I was advised that all DI will color your water's flavor to some extent. See my review of model FD15 refillable DI cartridge.
I vowed to never go longer than a year between resin changes. We only use about two gallons a day on this unit.So, new bank of pre-filters, new RO membrane, and new DI resin. My TDS is back down into the single digits. Oh, and the water tastes like - nothing. It is just pure, clean, refreshing water.
I am very pleased to have used this as part of overhauling my point-of-use RO DI drinking water.About a month ago, as I took a sip of water I told my wife how awful it tasted. I have been regularly changing my pre-filters on my RO DI unit. I had never recharged the resin or even the RO membrane IN 5 YEARS!!!!! Oooops. My TDS was 336 ppm. Compared to my tap water - it was identical.
Works with my Coralife RO/DI at a great price. Cheaper than most online places and the quality seems pretty good.
Works good. Lowered TDS to 0, Cl/Br to 0, hardness and alkalinity to 0. Leaves a bit of a funny taste. Switch the fittings on your RO unit so this comes before the taste filter then add an alkalizer filter at the very end for some great tasting water. Fixed my nasty tasting water that an RO alone would not.
Worked fantastic.Brought my RO+DI water from 10 PPM to 0.I fixed my system to produce 5 PPM into the DE-ionization stage, for longevity.I paired this with a refillable plastic filter and couldn't be happier.
Answer: yes
