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

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.

Size & Setup: The Aquatic Life RO Buddie 4-stage RO/DI unit is compact and easy to set up, making it ideal for smaller spaces or hobbyists who don’t need a large permanent system. Performance & Water Quality: Despite its size, it’s very effective, producing clean, high-quality RO/DI water suitable for aquariums and other uses. Maintenance Considerations: Because of the smaller filters, you’ll need to change the cartridges more frequently, depending on your incoming water quality and total gallons processed. Final Verdict: If you want a small, effective RO/DI system, this unit does the job well. Just be aware of the more frequent filter changes due to its compact design.

So this is my honest opinion about this RO filter system now I got the 50 gallon because I have a 60 gallon cube so I’m gonna give you the pros and cons and how easy is it to set up or not set up we’ll start with the pros pretty compact pretty easy well not pretty easy to set up. I’ll leave that for later. Another pro is that this product for $70 it’s worth the price another pro it seems pretty fast I mean in like the next hour you got a half a gallon and then the next couple minutes you get a full gallon now let’s start with the cons building this product. I figured out that this product was not the best to build. It seemed like the instructions were not very accurate, but that was on my hand. Another thing is that the faucet adapter wasn’t really the best I mean, don’t get me wrong. It’s good and whatever it is but definitely could rather there’s still some leakage that comes out even when you tight it so I have a problem with that, but that’s probably just on my hands with leakage. It’s a mixed opinion. That’s another con with me. It’s a mixed opinion about the leakage because when I first built it, it was leaking like crazy but the second time I rebuild it it wasn’t leaking so definitely make sure you’re having the cleanest cuts with the razor blade into tubing. Another thing is is that you another con is that you have to push your tubing really deep into the filter culture thing so then you don’t have other leaks. Another con is definitely they’re gonna still have guaranteed with the faucet adapter and then for easy to build, I would just say it’s all right for building, but it’s not expertise building either because again you have to get the cleanest cuts and then you have to focus on what to do. It’s not really my mojo. Don’t get me wrong, but building overall was kind of annoying. It was like you know the system itself is fine but building it is just not for what I wanted to deal with but definitely I had to rebuild mines but you know everybody’s filter system that they got from the 50 gallon is all different so I’m not the one to judge the filter but it’s pretty good overall

The product is a easy setup and works, the only con for me is that the male/female adapter that screws where the aerator sits is made out of cheap plastic and broke easily on testing the product. Since it was working before trying to remove and breaking i went to buy another.. the only problem with that is they don't sell the cheap plastic piece they sell a metal adapter. Why wouldn't you charge the extra 10 bucks and send your customers the better quality parts so we don't have to worry about getting the m/f adapter out of the faucet? other than that this product is as advertised, a great cost effective RO system for small aquariums and in my case small time growers.

Amazing it’s output is exceeding 50GPD

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.

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