Calgary drinking water, does it have chloramine?

[DomG]

Hi

Im new to reefing, looking for a RO DI unit and im not sure if i should worry about chloramine in Calgary drinking water. I would like a 5 stage RODI or is a 4 stage good enough? I have a 90 gal tank with a large sump.

Any advice would be much appreciated.

Thanks!

Hi thanks for the reply!

I saw that to but I know they stopped putting fluoride in the water even though it's listed there. Reddeer and Edmonton both have chloramine. So I'm still not convinced. I called the city and they couldn't tell me either way. Not sure what to do now? Do you have a Rodi of so which one?

I've got a 4 stage from BRS. Works great, water quality is great. Got it during a group buy so price was right.

There is no chloramine in Calgary tap water.

Coping with chlorine in Calgary
The Canadian city of Calgary, with a population of one million, is in better shape than most communities when it comes to drinking water supply. Its source is the abundant Bow River, fed by pristine glaciers in the Rocky Mountains. However, spring melt causes suspended solids and organic loads to fluctuate widely, and ranching activities and abundant wildlife can contribute faecal material and giardia (known locally as ‘beaver fever’) to the supply.

As a result, the city operates two water treatment plants with a total capacity of 900,000m3/d; chlorine gas is the primary disinfectant treatment at both plants. “Chlorine is one of the most cost-efficient means of disinfecting,” says John Jagorinec, senior water quality analyst for the City of Calgary’s water services.

Water treatment tour - Clarified water basin

Clean water is sent to the Clarified Water Basin, where sodium hypochlorite (chlorine) has enough time to disinfect the drinking water, killing micro-organisms and viruses that can cause disease.

Thanks for the info! I'm good on water now I'm deciding how deep my sand bed should be I think I'll go 1.5 inch and then I'll be cycling my dry rock!
