AquaticLife RO Membrane Replacement Cartridge, 50 GPD | Replacement membrane for 50 GPD RO Buddie and compatible aquarium or hydroponic RO/DI systems

Works great, compact, easy to replace. I haven't had any issues for 2+ years with this brand filter.

Dropped my water reading to 0 on my tds meter. Highly recommend this filter for marine tank use.

Perfect fit nice quality

I am not able to rate the quality and performance of this Reverse Osmosis Membrane filter due that it is the first time I will try it at home. It seems to be a very good value. I will monitor its performance in due time, and then I will be happy to provide an honest review. I feel confident that this 100 GPD Membrane will do a good job. I have an ill wife and some healthy grand babies at home that require good quality drinking water at home. I feel optimistic about this new product. We'll see. I will give it five stars for now and I will confirm my final rating later on.

As always, Aquatic life delivers good and quality product to save you a headache with your RO/DI unit. This membrane really helps in producing a god water for my saltwater tank. i have been using Aquatic life RO/DI as long as I remember.

This worked perfectly to upgrade my RO Buddie from 50GPD to 100GPD. My only issue was the seal was attached about two inches from where the OEM seal was situated. I removed the tape, slid the seal up, put the tape back on. I’m not certain this is required but did it anyways. If the filters are going to be shipped out like this, maybe the filter photo could be updated to reflect the placement.

I am not sure how we drank water before but now if it has not been run through the RO filter It tastes like metal. Who knows whats in our water. The water companies only test for 32 things in the water, There are a lot more than 32 contaminants in the water we drink. some of them build up to high levels because they are not being tested for or removed from one water shed to the next. So if you live down stream....you are getting all the build up from all the towns up stream. Get a RO unit and you will taste the difference. I have saltwater reef aquariums and have spent over 400.00 on RO units in the past. This unit is a steal.

Wow. What a great find. This brand at such low price. Get it it if the discount is still available.

Amazing product

I bought this because I was looking for a replacement for my RO Buddie’s membrane filter. This one was much cheaper and fits and works perfectly!

Works well

Perfect fit.

only removed 85% of the particles in my water. Not nearly good enough for my reef system.
