RO Unit

[squamishbc]

Mine in Chilliwack is around 60ppm in, and 1 out. I don't use DI as I keep nothing but 2 clown fish, and a little rock of mushrooms, and frankly never had an issue with that 1ppm that is left causing issues.

Info should be available on line from your water utility or city. Whether your water is chlorine or chloramine treated will determine if you need an extra carbon stage. A good quality 75 gpd RO membrane could get your TDS down to 0 and you may not even require a DI stage. A water pressure gauge is a good option as is a dual TDS meter.

I use RO water for coffee, tea, cooking, wine/beer making as well as making water for my tank. The unit gets a good workout!

Most of the time my water source in Vernon is Kalamalka Lake which averages 180 TDS. I recently replaced my 75 gpd RO membrane after flogging the original for a good 6 years. The old one was providing 1 TDS with the Kal Lake water, the new one gets it down to 0 TDS. I still use a DI stage for tank water. Occasionally the city switches me to the Duteau Creek source which is much lower TDS, somewhere around 50 IIRC. Many variables depending on where you live, where your water comes from & seasonal factors. It pays to do a bit of research.

Here in Surrey, we have between 10 and 15 ppm TDS, depending on the season. Spring time is the highest.
With such a low TDS, the filters last a long time. I have at least 5 yrs on the RO membrane.

I'm looking at the AquaFX barracuda on JLaquatics and the Spectrapure 4 stage on reef supplies. Any suggestions on which unit performs better and is a better bang for your buck.

Thanks.
