## Description

Detailed Description: Producing 99.99% pure water, this is a great system if you are looking for a reverse osmosis unit for your saltwater aquarium or hydroponics setup.

Review: Was hesitant at first to go with the 200gpd system as it's a bit pricey. I have had the system for over a year now and do not regret buying it from day one. I run straight cold tap at around 15C. With the boost pump going it will boost from 55 psi to 120 and steadily give me 175 gallon per day by calculation. Roughly 2.5 :1 for a ratio. Warmer water would even be better numbers than this The unit has been used about two to three times a week and just lately I have noticed the resin starting to change color. Tap TDS is @ 200 and was still 0 ppm out up to a few days ago now its 1 ppm out. Healthy fish keeping and happy fish keeper!
Review: The TDS after using for a month is still a little higher than I hoped for but seems to do a decent job

## Features

- 6 Stage Home Water Filtration System: Max Water 6-stage RO-DI (reverse osmosis deionization system) removes particles down to 1/10,000 of a micron effectively removing 99.99% of impurities after DI (deionization) stage. This includes reduction in bad odors, lead, fluoride, copper, cysts (cryptosporidium, giardia, entamoeba & toxoplasm) and other metallic ions from water leaving you with clean, clear water.
- Safe Aquarium Use: A RO/DI system removes contamits from tap water, making it safe for use in your aquarium fish tank. When it comes to water filtration, you're going to either have an RO or RO/DI system. An RO and RO/DI are almost identical except the RO/DI system has an extra filtration stage called the "DI or Deionization" stage which brings the water down to 0 TDS (total dissolved solids) after the DI stage.
- TDS Note: After the DI stage, the TDS drops to 0, however your water output may still have a TDS value. This is a result of the final stage of filtering using an inline carbon filter. Any unfavourable taste or odour left behind will be eliminated by this inline carbon. It's possible that the process will leave behind small, harmless carbon particles (60 PPM/TDS), which will gradually reduce.
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
