Twist-in 4-Stage RO/DI Aquarium Filter, 75 GPD | Four filtration stages: sediment, carbon block, 75 GPD RO membrane, and color-changing DI resin

How to Get Pure Water for Your Aquarium with AQUATICLIFE Twist-in 4-Stage Reverse Osmosis Water Filtration Deionization System If you are an aquarium enthusiast, you know how important it is to provide your fish and corals with clean and pure water. Tap water can contain chlorine, chloramine, heavy metals, nitrates, phosphates, and other contaminants that can harm your aquatic life. That's why you need a reliable reverse osmosis water filtration system that can remove these impurities and produce high-quality water for your aquarium. One of the best options on the market is the AQUATICLIFE Twist-in 4-Stage Reverse Osmosis Water Filtration Deionization System. This system is designed to be compact, easy to use, and effective in producing pure water for your aquarium. Here are some of the features and benefits of this system: - It has four stages of filtration: a sediment filter, a carbon block filter, a reverse osmosis membrane, and a deionization cartridge. These filters work together to reduce sediment, chlorine, chloramine, total dissolved solids (TDS), and other harmful ions from your tap water. - It has a twist-in design that makes filter changes simple, easy, and clean. You don't need any tools or mess with used filter material. You just twist the cartridges in and out with a quarter turn and replace them when needed. - It has a small footprint that makes it easy to place under cabinets or in limited spaces. It also has mounting brackets that hold the unit securely while mounted in a convenient location. - It has a high capacity of 100 gallons per day (GPD), which means you can produce enough water for your aquarium needs. You can also adjust the water pressure with a flush valve to optimize the performance of the system. - It includes everything you need for installation: tubing, water supply connectors, and drain connector. You just need a few simple tools and follow the instructions to set up the system in minutes. I have been using this system for over a year now and I am very happy with the results. My water parameters are stable and my fish and corals are healthy and vibrant. I also like how easy it is to change the filters and maintain the system. I highly recommend this system to anyone who wants to get pure water for their aquarium with minimal hassle and maximum efficiency.

I have a 100 gallon marine aquarium and I want the best environment for the fish and invertibrates. This filter mounts to the wall in our wash room so it takes up virtually no space. The system is very easy to install and I simply use a valve off of our water faucet to activate it. The results have been great. It even has bypass features for when you change the charcoal to let it pass thru. There are no leaks (very important) and its the best system I have used. Very good quality and I was very pleased with the value. If you have a need for an RODI system, this is the one I recommend.

This unit was purchased specifically for making clean water for Caridina shrimp. The value and quality were hard to beat in my opinion. The ease of filter cartridge changes is awesome! I was having an issue with me float valve and I reached out to their customer service team. They responded quickly and it was a simple fix that I completely overlooked in the instructions. Needless to say, I know that if I have questions or concerns, they are there and ready to help their customers. That goes a long way nowadays with internet shopping! Regarding water quality specifically, I have hard tap water from the city. It's loaded with TDS averaging above 300 and conductivity at 650+. After the initial flush of the filters, I was getting a solid ZERO on both parameters! I couldn't ask for anything better! The auto-shutoff solenoid is an awesome part that is included in with this unit. I'm able to fill my plastic tote with water and rest assured that the unit is not constantly running and wasting water. I would 100% recommend this unit to anyone, not just an aquarist, for their RO needs. Excellent product and value!

Great RO system, especially for the price. This kit comes with a little more stuff that most people might not need. I bought this mainly for fish and shrimp keeping but also for drinking water. The adapters did not fit my pull down kitchen sprayer/hose nor my bathroom sink, but it will fit a garden hose or a larger sink thread (I think my pull down hose is 3/8" and is much too small for the step down adapter from the garden hose size). I had a homemade stand that I installed it on. The main issue I have that makes it 4 stars and not 5: these connectors love to leak. I had to adjust them several times outside (while it was raining lol) to see if they would stop leaking. They would, but if they get moved slightly they can start leaking again, so when you set this up make sure you can see it won't leak when you turn it on (I had to keep going outside to the garden hose - I'll install a spigot on the side of the stand that I can connect to periodically I guess so I don't have to run around and turn it off). Once you get the tubes securely fastened and positioned how you need them to be so you don't move them much or at all when using the system, there are no leaks. Initial testing shows 1 or 2 ppm TDS if not 0 - those TDS meters are not perfect but it was moving around 0-3 ppm. Water tastes great. My city water pH is currently high at 8.4-8.8 (which is why I bought this). Tested pH was around 6.4-6.6!! 75 gallons per hour is a little over 3 gallons of RO water per hour. I'm using 5 gallon buckets for now until I get longer tubing or figure out a better solution - but if you're like me it takes about 20 minutes for the waste water to fill a 5 gallon bucket if you have a garden spigot on about a quarter turn. This equates to 15 gallons of waste water for every 3 gallons of RO water, so about a 5:1 ratio which is what I expected. My TDS overall is not that high (160 when testing the waste water), so I could use it for plants, just nothing that doesn't like high pH. tldr; works as advertised, install not that difficult but the tubing is sensitive and may leak and need adjustments but will work fine after making said adjustments. just have someone with you if you're not installing it in a location where you can turn the water on and off and see the unit at the same time!

Easy installation and perfect size. Yielding 75 gallons per day, its more than enough RO Water for watering my greenhouse ornamental plants,

This is a really good product. I bought the same unit 2 years ago and it worked great till some of the tubes degraded . so I got the replacement. it is very easy to install and works like a charm

I love this reverse osmosis system; my water changes have become so much easier. And the customer service is amazing.

Hook up easy and looks good and works great

This item so far did a great job for my aquarium. Definitely a good buy.

Absolutely amazing product. With every penny spent on it. You cannot get water any cleaner than this.

Good system it filters my 450 tdm tap water down to 1 or 2 tdm, my tap water is 50 tdm away from needing 2 sediment filters. It works fine for my 50 gallon aquarium needs.

良いです

Product arrived broken. The waster water valve part had snapped clean off. Tried gluing it back on to no luck.
