Color: 6 Stage 100 GPD RODI System


Features

  • 6 Stage Home Water Filtration System: Max Water 6-stage RO-DI (reverse osmosis deionization system) filteres particles down to 1/10,000 of a micron effectively filter out 99.99% of impurities after DI (deionization) stage. This includes improvement against 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 filter out contaminants 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 filters.
  • Simplified Installation: Our systems are designed to help installing and maintaining them easier. Quick Connects are color coded to make knowing how to install the system quick and easy. All filter housings are labeled for easy filter replacement.
  • Quality Tested: We consistently provide products and services that meet customer quality requirements.
  • Why Max Water: We have 15+ years of experience in water filtration industry providing solution with a smile to millions of families across North America. Make Max Water your solution to all your filtration needs.

  • Zero TDS
Color: 6 Stage 100 GPD RODI System
instruction booklet isn’t very self explanatory but overall easy to set up with the help of YouTube. After flushing according to instructions, my TDS meter was reading zero within 30 minutes. At 60 PSI this product was producing just about 3 gallons per hour which is slightly lower than advertised however it still fit my needs. I’m overall very satisfied. ... show more

  • Worked well for a year now!
Color: 6 Stage 100 GPD RODI System
I use this unit for my saltwater reef tank. A year later and I’ve done nothing but added a second DI canister. I added the second one so that I can refill them with cation and anion resins separately, since they don’t exhaust at the same time. A little better than the mixed bed, imo. Great unit. No complaints. Fits well under my bathroom sink! ... show more

  • Less waste water
Color: 6 Stage 100 GPD RODI System
Produces about half the waste water as my previous rodi. Happy with the output and water quality

  • Bought to remove nitrates
Color: 6 Stage 100 GPD RODI System
Make sure you flush first. At first ph was neutral coming out from RO membrane and high nitrates (from my tap) then after DI zero nitrate but ph 9. This then settled down. TDS is not zero but around 24 which is fine form me. There is double waste water to water produced.

I purchased this unit for my aquarium. I use it about once a week to create water for my ATO I installed a T in the copper pipe and mounted this to it. Super easy if you have plumbing skills. if not, I think this could be very complicated Once installed, it has worked great. I can do about 30 gallons in eight hours. ... show more

Looking for a zero TDS rodi system for my reef tank. This system got my water from 450 TDS to 25 TDS, a 95% reduction, but NOT zero
