I came to find out that Calgary is charged double the water used (because of wastage!). WTH :S So RODI unit is actually not coming out to be cheap. To make 5 gallon water, I will be using 20 gallon and be charged for 40gallon! And that's for only top off water :S Can anyone please clarify me on that?

I am just doing the calculation since moving to an apartment might be an option for me and I will have to pay the bills.

You pay for the water delivered to your abode and your wastewater carried away. It's not exactly double because the wastewater is a smaller percentage of what is delivered to account for things like irrigation and evaporation and so on. So you would be charged for 20 gallons delivered, and some amount less than 20 gallons for wastewater. I forget the exact ratio they use.

But even though you pay for water to AND from your abode, realistically, I don't think you will truly feel a huge impact in your water bill for the size of tank you have. It's part of the cost of having a tank. Overall it would likely be one of your more nomimal costs.

Oh Maaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa an :cry: The cost the COST!!!! :cry: :twised:

That said, if you're uncomfortable buying an RO/DI, just don't buy one! I don't think anyone is suggesting to buy one because they want to trick you into making a bad purchase. :p It's more of a convenience factor to be able to produce your own RO/DI. Plus, another thing to consider is that the grocery store water is RO, but not RO/DI. That means if you properly maintain your RO/DI unit, the water you produce will be superior to the water you buy at the grocery store. And last but not least, it just sucks to carry those jugs around: water is heavy. :lol:

The only reason I suggested to watch out for rejection rates is, well, 1) it's kind of interesting and thought you might find it interesting too, and 2) You will indeed notice a difference in the depletion rates of your DI resins if you go from one to another. It might not be so much a cost factor but the inconvenience factor of having to replace that stuff every so often.

Hope this helps!

Are you sure you're not my dad? That guy has figured out, to the PENNY, how much it costs him to water his grass using his sprinklers. "TO RUN ZIS (he's Dutch, therefore the accent, thought I'd better clarify that) SPREENKLER VOOD COST $3.64 PER VEEK. $3.64!!! $3.64!!!!! OH ZE INHUMANITY."

Can't beat the vertex rodi unit

Thanks for the information. Definitely useful :D

LOL. I am too young to fit in the scene ;) :razz:

Its really not about the cost. I always try to give the best "I can afford" to my fish even if that means to not buy a nice shirt for a change (my fishes "wear" more brand stuffs than me :lol:). I get my scholarship, I go buy something for my fish instead of something for me :smile:

But this month has been horrible for me in terms of the tank (you might already be aware of that through my several "complaining" posts). Burnt skimmer, burnt reactor pump, dead fishes, foods + selcon, dead corals.....sometimes, its a bit harsh for me on my small amount I get as scholarship :cry:

And this hobby is not very "rental" friendly and with RODI...ummm....yah...just adds another "layer" to that :razz:
