## Overview

The Aquatic Life RO Buddie 3-Piece Bundle includes sediment, carbon block, and color-changing DI resin cartridges designed for superior water purification. With 5 micron filtration, a 2,500-gallon carbon lifespan, and a visual resin depletion indicator, this set ensures consistently pure, chlorine-free water. Compatible with most RO/RODI systems, it offers easy maintenance and visible filter status for hassle-free, high-quality water filtration.

## Description

For use with Aquatic Life RO Buddie+DI Reverse Osmosis Unit. Five micron sediment filter traps sediment and other particulate matter like dirt, silt and rust which will affect the taste and appearance of your water. The activated carbon in the filter reduces chlorine and conditions the water prior to the RO membrane. The sediment and carbon filters are both rated for 1,500 gallons of water to pass through before replacement. In addition, the sediment cartridge housing is made of a special translucent material that allows you to see build-up on the cartridge itself. After the water is filtered by the membrane, there is usually a small amount of total dissolved solids (TDS) left in the water. In certain non-drinking water applications, it is important to remove the remaining TDS from the water. This is accomplished by filtering the water through a resin that is charged with cation and anion resins (H+ and OH-). As the resin absorbs the TDS, it will change color. When all resin has changed color, it is time to replace the DI filter.

Review: I've been using the rodi buddy for a couple years now. It's perfect. It's small, easy to change filters, cheap compared to what you see on BRS. Take maybe 45min to fill a 5 gallon bucket. Always reads 0 on the TDS meter. When you see 1 on the TDS meter it is time to change the charcoal filter. I need to mention the TDS meter is sold separately but should be bought when purchasing the rodi buddy. Prestine water quality and simple functionality.
Review: Have had this filter for quite a while. Once my second set of filter cartridges. Consistently give me 1 TDS output. Combine that with the price and it's hard to beat. Its only 50 gal per day, but I have 3 nano reef, so it's not a problem for my needs.

## Questions & Answers

**Q: What is the other filter that is needed for the rodi unit?**
A: Rodi has a 3 system unit and a 4 system unit 
And a 5 system unit.
A 3 system unit is sufficient enough !

**Q: Does the 3-pce bundle include clips for the di resin cartridge to attach to the ro buddy?**
A: No, the replacement cartridge bundle does not include the clips to attach the resin to the membrane housing. This is intended to be a replacement cartridge pack and you use the same clips that came with the RO Buddie. If you purchased the RO Buddie without the DI in the beginning, you can always purchase the add-on inline resin cartridge and it includes the clips. https://www.amazon.com/dp/B00DSP57BQ/ref=cm_sw_em_r_mt_dp_YYTHDS5Q1P6SQ607Q5NJ

**Q: Is thos 100 gpd or is it 50 gpd**
A: This is for the RO Buddie+DI 50 gallon per day model.

**Q: Can I use water right away or do I need to flush?**
A: It’s always important to flush the carbon cartridge incase there are any carbon fines from the cartridge manufacturing process. Flushing the carbon cartridge for a few minutes prior to installing the membrane and DI cartridge will ensure any possible carbon doesn’t plug the membrane.
