Aquatic Life DI Color Changing Mixed Bed Resin Cartridge, Aquarium, Hydroponics

Easy install on my RO system dropped my water TDS from 47 to 0 .

Why did you pick this product vs others?: Works well.

Excelente producto definitivamente bajo mis ppm a 0 lo recomiendo

I bought this and the RO system. I tested the TDS when I first used the system. Not only was my TDS reading 0, it remained at 0 for about 6 weeks. I did another test today as the filter is showing its use. My reading went from 000 to 002 in just over 2 months of use. Very good for the use I'm getting out of it. I keep a 5 gal. bucket full of RO water. Not only do I use this water to top off my aquarium but I use it to make coffee and I cannot be happier. Everyone suffers from the coffee makers slowing down. Well mine did, ran vinager through it several time and then started using RO water and have not had another slow down. My wife will use the RO water to make her beverages with.as well and she is very happy with the results. Update: I had downgraded this item from 5 stars to 3 stars due to the fact the resin in replacements was not lasting long. I have upgraded to 4 stars as the unit is doing a great job. The difference is I am refilling my own tubes now. You can buy bag of resin, unscrew the cap, fill tube with new resin. The best part is the cost savings. These, if you buy them is around $32 each. A bag of resign is about $48. I have already refilled the tubes twice (2x32=64-48= savings of 16). There is still enough resign to fill another 4 or 5 tubes. That's almost a $200 savings once all resin is used. The best part is you can have a filter ready when you need it and not have to order one or order ahead of time. http://www.amazon.com/gp/product/B000X92KOC/ref=oh_aui_detailpage_o07_s00?ie=UTF8&psc=1

I have purchased a bunch of these over the years and they consistent bring my TDS down to 0 for my RODI water supply. Make sure to double check the caps as they sometimes come delivered untightened and can leak after installation

Exelente este filtro

Overall, this is a good product. It lost half a star for having no instructions, half a star for the first unit dying unusually quickly, and a full star for being incorrectly described in the listing. Beyond these issues, though, it works well. First, the units I received were not green, which is important because the unit's coloration is how you know if it is still good or needs replaced. The units I received were both blue/black, as you can see in the photos I uploaded to Amazon. The listing, when I bought the items, did not say anything about there being different color models; it only discussed a green model, and I wanted green anyway for aesthetic reasons. The only reason I discovered blue/black was a second model was by going to the company's site and looking through several documents there. The listing should accurately describe what you'll receive. Hopefully, by the time you read this, it will be updated. Second, the unit came with no instructions. It didn't say which end the water should enter and which end the purified water exits. The answer, by the way, is water enters the bottom and exits the top, which you can see from the documents on the company's website. The unit also has a particular kind of tube seal that is not obvious: there are white baskets sitting in a hole, you push the basket down and shove the tubing into the hole, and then you pull the basket part up and clip a blue U-shaped clip on. That part was easy to figure out. How to remove the stoppers that are in the basket when the unit arrives (and how to get the tubing back out of the basket) was not obvious. If you just pull and pull and pull on the stoppers, nothing will happen. If, however, you simply push the basket down and then, while holding it down, pull the stopper out, it's really easy to remove them. Same with tubing: push the basket down, pull up on the tubing, and voila, done. Finally, my unit turned brown (the color that the black/blue ones turn when dead) exceptionally fast. Within a few hours of use, I had a mostly brown unit. You can see that from the other image I uploaded. Amazon sent me a new unit, though, which was amazing (as Amazon customer service always is). Beyond that, I love this unit. It's a great price and makes the amount of water I expected. My water hardness is way down from using this unit, and my fish tank is very happy. It was easy to install and put together with the main Aquatic Life unit. The few questions I had were easy to answer by going to the company's website and finding a manual (which should be included with every order, but wasn't for either of mine). One last word of warning: be sure that you don't put this somewhere that has high pressure. Or, if you do, make sure you buy tubing that can handle it. I put mine in the wrong place on a solar water heater and the pressure was too high: it blew a hole in the tubing I bought and leaked quite a bit. However, I just changed the tubing, reduced the pressure, and it has worked fine since. Overall, I recommend this unit to others. Just be advised that you might not get a green unit, and go straight to the company's website for instructions if you need them. Otherwise, this unit works well for me.

TDS 0!! Haven't had to refill resin in over a month. We can tell the difference even after the RO Suggestions for those comments I read. You need a RO system before this cartridge. It is a finisher not for full filtering. I also have a water softener on whole house. For the comments on difficulty opening and resealing cartridge. Hard to open first time. They fill it with resin rather full. Before putting top back on I suggest you use a bit of gasket lube (food grade) on seal and threads. You need to tighten well or it will leak. I was able to open and close easily with no leaks. Might want to put a elbow on supply side (bottom) to prevent kinking of line. I would recommend to all.

This cartridge works great and I can get a bought 6 months out it before I have to replace it. HOWEVER The TDS of my supply water is 20ish and I only use this to filter about 10 gallons a week. The people complaining that it doesn't last long enough are either A) using supply water with a high TDS (100+) or B) Using it to filter large quantities of water.

Good quality product
