Water Filtration
I thought it would be interested in seeing what kind of filtration most people use for their tanks.

Keep in mind people's locations. Those at the west coast have ridiculously low TDS out of the tap (like <20 ppm) and many of them use DI only or prefilters only (sediment and carbon) or sometimes nothing at all.

at even 20 TDS I would think that you'd BURN through di resin extremely fast to the point that running only di would be much more expensive than your typical operation of a full ro unit. anyone using only di able to tell us how often they have to replace it?

I use a 6 stage BRS RO/DI chloramines unit for Edmonton water. Output is now 0 ppm TDS. My costco RO only system unit measured 3-7ppm TDS after a filter change. Sounds bad but that's about right for a 97-98% rejection rate. I'm guessing the same Costco unit used in the lower mainland would give you readings of 0 ppm and filters/membranes would last a good deal longer.
