AQUATICLIFE Aquatic Life RO Buddie Cartridge 3-PCE Bundle, 1-Color Changing Mixed Bed DI Resin Cartridge, 1- Sediment Cartridge, 1-Carbon Cartridge

Always arrived quickly and was the exact thing I was looking for

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.

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.

Very happy, my replacement cartridge is here and in great condition

deionization filter turned completely brown after about 70 gallons
