Reverse Osmosis Water

I need to get reverse osmosis water for my saltwater aquarium but don’t have it in my budget to buy an entire reverse osmosis filtration system. I am wondering if anybody knows where you can buy reverse osmosis water for cheap or if something like the Pur water filter ration system that hooks up to the faucet would make it decontaminated enough and then add some dechlorinator to it.

 

RO Buddy is the cheapest reverse osmosis system you can get. Hooks on your faucet.

Generally speaking any LFS (Local Fish Store) that has Saltwater fish will sell RODI water and RODI/Salt pre-mix. As mentioned above the RO Buddie RODI sytem costs $60 from amazon:



PUR is probably better than tap but still not recommended as it doesn't filter many of the things out that you want gone from your water.

 

I got an RO Buddy for about $50. on Amazon. Installation was a breeze since I hooked it up to an outside faucet on the patio and leave it in a plastic storage seat. RO drains into 18 gallon totes and drip tubing runs the waste water out to some shrubs which are doing fine so far. Filters are cheap and only need changing about once a year.

 

Yup, when I show people the RO Buddie, they are stunned at how little an RODI system can cost.

 

I would only recommend an RO Buddie if you don't have chlorine or chloramine in your source water.

Note that the RO Buddie carbon stage is something like 1/20th the volume of a full-size 10" block. Also, BRS considers 0.5 mg/L chlorine breakthrough as the failure point but as little as 0.003 to 0.02 mg/L is toxic.





You might think you can dechlorinate the product water to protect the fish. You can but the RO membrane will be damaged by exposure to chlorine/chloramine and any DI resin will be rapidly exhausted. You would have to somehow add dechlorinator before the RO membrane or just get used to replacing it regularly.
