Aquatic Life RO Buddie Plus DI Four Stage Reverse Osmosis Deionization Unit 50 GPD

delivered fast and easy to install, water tests 0 tds which is perfect!

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

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,

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.

The item is perfect and I have used it staying in UAE I recommend to buy from only and only fulfilled by Amazon for this other venders cancel orders after days of waiting. This is the best ro for a aquarium setup.

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

Overall the product is working fine but the filtered water delivery is very very slow unlike the waste water which is very fast. It needs a booster pump may be.

Easy install. It has everything you need to complete the install successfully. The only thing is it doesn't come with anchors, only screws

Best RO filter easy to install 0 TDS output

I purchased the RO Buddie 4-stage RO/DI 50 GPD filter. This is for my small freshwater setup which includes seven tanks of varying volumes with a total volume of just under 100 gallons. I went with the RODI and not just RO system because I am trying to decrease the alkalinity of my water. So far so good after filtering 10 gallons of RO/DI water. It's very easy to set up and my water parameters have come out excellent with zero PPM TDS and zero EC (see attached photos, the meter was calibrated today). I live in Coastal Georgia and have moderately soft water parameters from the tap at around 150 PPM TDS (total dissolved solids) with a significant amount of EC (electrical conductivity) due to the high amount of minerals in the water. So basically very low sediment but high mineralization and somewhat moderate GH and KH. I have had a hard time keeping my South American tanks at good parameters for my tetras to breed and this will help immensely if it continues to work as it has so far. A Few Tips: - tighten the deionization filter cap before you install, I had a small leak as mine was somewhat loose but that was easy to fix and find and I just tightened the cap of the actual filter body itself and the leak stopped. To do it correctly I took all the hoses out and tightened it that way so I would not torque the hose connections. - this can be run off of any hose or even many kitchen and bathroom sink setups if you take out the aerator from your faucet. I am personally running it off of my laundry room and it's running beautifully as there is both a supply of cold water and a drain for the wastewater. - if you're going to install it in your laundry room all you need is a t-joint hose splitter or some other sort of double hose splitter that fits the receptacle for your washing machines supply water and gray water drain (see attached photos of my setup, everyone's will vary and I had to measure mine specifically as there are a huge variety of hose splitters) - if you are are doing a laundry room setup like mine where you can mount it close to the washing machine then the amount of hose provided in the kit will be more than sufficient. However if you are doing some other sort of setup you may want to buy additional hose, as you will need not just the proper amount of hose for the treated water but also the appropriate length of hose for wastewater. You could of course use a bucket but if you want to appropriately drain it to a sink or drain, getting additional hose maybe necessary. - if you are using this for a freshwater setup like I am you must absolutely get an additive that will keep the GH and KH at appropriate levels. RODI water by itself will kill fish. - Read the darn instructions. For a cheap system like this they are actually fairly detailed and obviously written by somebody who speaks English fluently. - having a solid set of channel locks or a wrench that will fit into a small area, as well as Teflon tape for the female ends of the threaded connections, will help reduce the potential for leaks. I am on city water that withdraws from a river and and underground aquifer and it is at a fairly high PSI as I live only 2 mi from the treatment center. All in all I am really pleased so far as this is the least expensive system I could find. This would not be an appropriate system for drinking water as the pressure/supply would not be great enough to fill a glass in a reasonable amount of time. Right now I am averaging about 5 gallons of treated water every 90 minutes (around 80 GPD) which is far above the 50 gallons per day that the system rated for, although I expect that to eventually go down as the sediment and carbon filters begin to fill with debris. That said, I am currently probably experiencing closer to a 75 GPD or even 100 GPD system which got $70 is impossible to beat. As an added bonus when the RO finally wears out I can replace it with one of their 75 GPD or 100 GPD rated filters so long as I swap out the The 450cc flow restrictor for an 800cc flow restrictor, thus functionally increasing the output of the system. This will of course wear out the DI filter faster. I will update this review if anything changes but so far I am pleased. For some reason Amazon's AI wants me to comment on the noise level which is silly for a system of this low of a flow rate. If it's making any noise louder than a few gurgles and bubbling sounds that you can only hear when you are right next to it then there is probably something wrong with the system like over pressure or an incorrectly installed hose connection which is creating suction and/or air intrusion somewhere. So, tldr, it doesn't make any noise. In summary, it's a cheap effective system that took me about 20 minutes to install with just the parts in the box and the hose splitter I bought. Hard to go wrong at this price point. I would recommend this to anyone who needs a small amount of water for weekly or bi-weekly water changes and is trying to keep the GH and KH of the water column down (i.e. slightly acidic or neutral). note: The picture system has not been fastened to my wall yet nor have I done any hose management so bear that in mind as well.
