Anyone use this RO/DI filter?


Mar 9, 2015
I have recently got the Reverse Osmosis RO+DI Filtration POQ-4B-100 and am wondering if anyone else has used it? i read one, and only one, review where the person said it started producing ammonia after four months. This was after purchase, but most of the reviews were 4+ stars, but not all reviews were for aquariums. Greatly appreciate any info or insight if anyone has used this filter, link is here if needed.

Thank you,

I would worry about the water supply more than my RO unit if the output included ammonia. This would mean something dead has entered the system. I really don't think there is a lot of difference in RO units per se. The filters you use, keeping them clean and monitoring for replacement (TDS meter required) have the greatest impact. The flow hardware are all pretty much standard with interchangeable filters from many suppliers.
