Inexpensive water treatment system

I would say spend the extra money up front and get a good ro/di unit. in the long run this thing will cost more w/ having to replace the filter cartridge every 150 gallons.
 
I used that filter before I got my RO/DI and still use it on occassion even now since it's downstairs in the laundry room closer to my Q-tanks.

It's just a DI cartridge pretty much. How much you'll get out of it depends on your water quality out of the tap. You'll have to change out prefilters and DI resin just the same with an RO/DI unit

Works fine if you have a smaller tank (~30 gallons and under), but very INconvenient if you have anything bigger.

It might work for me as I only have 30 gallons and likely another 30 gallons in the future. I was concerned that the water quality will not be good enough but if it is, I don't mind the hassle of it.
So you think it would provide suitable results?
 
It depends on your water quality. If you're on well water or have very hard water (high TDS) out of the tap, then you might get 50 gallons or less.

But if you've got very soft water with very low TDS, then you'll get much more mileage. Around here in Vancouver, we've got around 1 dKH (if that) and TDS on a good day can be 10 ppm or so. As a result, this filter (along with my RO/DI cartridges) seems to last forever (up to 150 gallons) because there simply isn't very much stuff to filter out in the first place.
 
On my cheap Hagen test kit my GH comes out to about 120ppm or "moderately hard" I don't know about tds, I've been looking online and can't find a water report for Montreal. I remember when I was a kid my father would take me fishing and our outboard motor would get choked by seaweed. He said it was because of phosphates in the water. I know that most detergents have been phospjhate free for years now. But I wonder how much phosphate is in the actual water. I need to buy a phosphate kit methinks.
I'm not even sure of the r/o water I'm buying at the grocery. It might not be any better than tap.
 
A city the size of Montreal would definitely have detailed water quality reports available. If it's not online, just phone or email the city.

You can also ask your LFS and other local hobbyists. Montreal should also have a reef club and those guys will know the local H20 inside and out.
 
I think you should spend the extra on ro/di, everyone i know has had good quality water filtered by them and nothing has gone wrong with the water. IMO get a ro/di.
