Can I drink water from this filter?
Answer by ChewyJan 13, 2018
This system is a reliable source of economical filtered water, this system is available in a 50 or 100 gallon size to meet your aquarium needs.

Does this filter replace the conventional hang on the back filter for my fresh water tank or just supports it? How expensive are the replacement cartridges/filters?
Answer by ChewyNov 09, 2017
This reverse osmosis system is designed to thoroughly filter the water before it's used in your aquarium to remove any contaminants from the tap. The unit will produce 50 gallons of RO water per 24 hours when it's running. You'll still need a filter on the aquarium to handle waste produced by your aquarium's inhabitants. Cartridges can last as long as a year depending on how much water you need to produce.

Is the membrane and the resin the only canisters you need to replace? Also how do you know when it’s time to change the membrane?
Answer by ChewyJan 08, 2018
The Carbon Cartridge will last up to 6 months. The TFC membrane will nee to be changed every 1-2 years. The DI Cartridge (resin) will need to be changed once the resin has changed colors. The Sediment cartridge will need to be changed at every other carbon cartridge change.

When the system is functioning properly -- what is the TDS reading of the RO/DI water?
Answer by ChewyMay 29, 2018
The RODI unit produces close to 0 TDS water.

RO Buddie 4 Stage

Very easy to setup and install. My 45 gallon reef tank parameters are all in check now that I use this ro system for 5 gallon water change every 2 weeks.

Wastes 4 gallons per gallon of clean water, can't hook up under sink

I got this for a humidifier. I looked up YouTube installation, this model is one that is supposed to connect to your sink faucet. NOT under the sink, unless you want to buy extra parts first at a hardware store. One tube is for clean water, another discards 4 gallons of "waste” water for every gallon of filtered water. I live in an apartment, and don't have the proper space for the waste water to go. It also seems very wasteful. I hope to find something that can run under my sink and waste less water

Well worth it for small setups.

This system has been hands down the best for me only having a 50 gal reef tank. It saves me money from going out using gas and money for buying water. The naysayers will say this system is horrible and 101 things but for the price and if you have a small setup and being compact even make it portable if you want to it's well worth it. I get zero PPM from my TDS meter and zero on chlorine from salifert test kit. Today I swapped out the filters and DI resin let it run for a bit. It's back filtering my tap water.

Delivered in under 24 hrs

I ordered on Saturday around noon I could not believe that my RO Buddie showed up at 11am on Sunday. That is insanely fast shipping. I just purchased RO water from my lfs yesterday so I won't be installing this until next week but I expect it to work as great as I hear.

Must have for aquarium keepers

If you mess with shrimp, discus, or any aqautic that requires remineralized rodi water, this is hands down the best value per gallon. It's pretty quick too!

No more LFS water for me

Got this RO unit and let me say after filtering water and testing, it's 0 TDS. I'm in Queens NY. Chewy has it at the best price online and their shipping was super fast also and very simple to set up and start using. After setup make sure to run for 30 mins to prime the unit. All in all this unit is well worth it and I highly recommend it.
