Aquatic Life RO Buddie 4-Stage Reverse Osmosis Deionization Water Filter System RO/DI Filtration Units for Aquarium, 50 GPD

Even with a 2 filter system and softener in my house my hardness is good. My tds was still over 300. Using this first run I got a ph of 6.3 and a tds of 15. Comcidering from the tap my ph is 8.5 and my tds being over 300 I can't complain. Also got a 2 gallons of water in 40 min. Like many others the faucet fitting does not fit. Maybe knowing many homes have a 13/16 fitting not the "standard" 15/16 they could include more than 1 size. I ordered the adapter from home depot for $5. So after 2 gallons its working fine. If I have any issues I'll update.

Simple design and easy to set up. No leaks right out of the box, fitment is awesome. if you're leaking - get some plumbers tape, problem solved. filtered into a 15gal tank in 4 hours. Had it hooked up to a quick disconnect with my garden hose outside, so i can fill my 3x 15gal tanks for my carnivorous plants (mostly sarracenias and some fly traps). Tested at pH 8.3 and 0 ppm - perfect for my plants (since the bottled distilled water i nornally buy tested at a pH 8.9 and 1.0ppm).With the set up and replaceable filters, this is definitely your best bang for your buck, if you have carnivorous plants to water!

Amazing value, genuinely amazing considering the price, great packaging and the manual is in full color and is great. Comes with literally everything you need except for a drill to mount it to the wall. It even came with a razor to cut the tubing, which was very useful because I don’t have a razor. The water came out at .01 EC which is pretty good for my awful city water that’s at .550 EC. I’m using this to water my cannabis plants and it is working great. Would highly recommend for anyone who’s using it for hydroponics or for aquatics. I just keep it underneath my sink until I use it.

Soooo I have well water, test about 820 TDS, I have this thing hooked up outside to my hose hub because it’s the highest pressure and the only fitting on my property that fits these adapters were uselesspart of the reason for the 4 star other being flow I’m hardly getting over a gallon per hour out of the 100gpd model should be more like 4 gph, I got 4-5 gallons while was gone for 5.5 hours. Also puts out a loooot of waste water compard to what it make, probably 5 gallons of water every 20-30 minutes of that. buuut it works well enough for my need I’m happy with what I spent it does the job PH even comes out perfect for my needs, only question is….How long will the filters last at this filter rate replacements are a liiilte strep IMO at like 55$ I can replace the entire system for like 25 more $

Assembly was a breeze. I followed the instructions and flushed the filters as directed. My output is very good delivering 2 gallons per hour (50gpd filter). I tested the filtered water and it registered 0.00ppm. This is doing exactly what I had hoped. My cost per gallon factoring my initial purchase and expected cartridge replacements looks to be roughly 1.5 cents per gallon. We have been buying filtered water at the store for 50cents per gallon. We use that as our drinking water. It's a hassle and expensive. Instead we will now use this filter. I'm thrilled with how this turned out.

Wonderful, wonderful, wonderful! What a well-designed, easy to set-up and use product, not to mention dirt-cheap (for the RO market). I added a Y adapter to my washing machine cold water inlet (garden hose threads) the day before the RO buddy arrived. After opening the RO Buddy package (and having watched the installation video twice). I had the unit installed within 15 minutes, and up and running after the 2 flush procedures within 45 minutes. My water pressure is about perfect for the unit as it produces a gallon of RO water in just under an hour (RO unit flow rates are way over-rated, and are more like 50% of what is stated, so a 50 gallon/day unit should produce realistically 25 gallons per day, or one gallon per hour at average home pressures. Higher pressure can get you closer to the stated 50gallon/day rating, but it’s much more wear on the RO membrane, ie. shorter life).Coming from experience with RO units (for aquaria and orchids), if you’re trying to decide between the 3 and 4 stage units, only go for the 4 stage if you need really pure water, as in reef aquaria; the DI resins, the 4th stage, fill very quickly and have a short life ($). I’m getting 2-3ppm consistently after running 20 gallons through the RO Buddy, down from my tap water’s TDS of 180ppm, and that’s just fine for freshwater planted aquaria and orchids. Saves me a bundle not having to consistently purchase the expensive DI (4th stage) cartridges.
