where to get RO/DI water?

[Reef-Geek]

Has any one tried with water in Canadian Tire? they seem like RO water contains 0 minerals, for $4.99 you can 5 gallon. I only have a 34 gallon RSM so I think I'll change 5 gallon every 2 weeks, is that gonna be ok?
or does any one recommand water from super store or walmart?

That works, but $10 a month is $120 over a year, so in 1 year you've pain for a half decent R/O unit.. and also don't have to go to canadian tire to get water. Lower startup cost though, and that's usualy the expencive part.

when i have my 33 g, i survive by using DI tap water filter good for few months use.. but if you are planning to get bigger invest on a used or new RO/DI units less hassle in the end..

you never replace your membranes or media??

sems like you would need to consider that cost per month as well IMO...

for a regular 5 stage ro/di filter, how long does the filter media last? and how much to buy the new medias? Thanks

you cant sit there and say walmasrt is good or cdn tire is good...
It comes down to how the staff are maintaining their filters and this is not subject to store names...so your experience at each location could vary greatly.

Buy a TDS meter, they actually sell them pretty cheap at canadian tire...lol

and just test yourself before you buy.

I'd also suggest getting a TDS meter. Much better at figuring out if you need to change your cartridge or not.

Also, from a water conservation standpoint. I like the DI unit because it doesn't produce any waste water. We have very low TDS so I'm sticking to my DI for a while. I've actually budgeted for a BRS RO/DI unit but I'm still deciding if I want to create waste water that just gets dumped... it makes me feel bad..

I get a TDS as low as 8ppm.. most days it is about 14 or 15. I'm about 2 kms from the Coquitlam watershed so I'm lucky that way...
