excellent product
this RO system is low cost and highly effective with the individual filters having good longevity, used for my carnivorous plants and fishtanks in an area with very hard and chemically treated water, produces about 2 TDS as final output

Blue resin life
I brought this product. I am very happy with the result, but now the blue resin filter has turned a light brown color and the TDs are high. If any one knows how many liters of 0 tds water we can get in this resin filter before it turns to brown,

Works as advertised.
Does what it says on the tin. 50gpd took a looooong time to fill my 400l aquarium. But its great for water changes and keeping the reservoir filled.

Great system and very cheap, Worth pointing out if DOES NOT come with a Chlormide filter and have to be bought additionally

J'ai fait l'achat de cette osmose pour mon aquarium d'eau de mer il y a 6 ans (en 2020). Mon père l'a également utilisé pour ce faire de l'eau osmosée pour sa machine à apnée du sommeil. Ayant une esu très dure et contaminé par des Pfas/Pfos, je peux vous dire que cette petite osmose fait le travail à la perfection, et donne une eau de première qualité. Je m'en sers même pour mon eau potable à l'occasion. Vraiment, je recommande fortement cette osmose, vous ne le regretterez pas!
