It's really neither of those things. For some time I've read on here about the advantages of ro
. One might even say that the majority of posts on the simply say that's all you should use. That I can remember, I never saw a post making a distinction between FW
, nor anything on dosing essentials that are removed. Even from the get-go of this post , which was just a question of if I should mix the 2 for awhile to ease into the 'new' water the answers were just do the switch.
I never gave it a second thought until someone mentioned not to use it for FW
; the I went looking to validate the statement. So, no it's not a science experiment, I don't want to 'play w/ my numbers.
However if you consider your time to be worth something I would wonder what the true cost benefit number is for the ro
filter once you factor in dosing, testing, mixing time and costs. For FW
it sure isn't filter the water - use the water as compared to using bottled water as I do now which is open the 5g jug and siphon in.
Too late for me now, as I've already made the plunge so I'll use it for both FW
For others when the ro
discussion is broached, it might be useful to make the distinction before recommending it.
And for the record, it was Bob Fenner over at wetwebmedia whose posting first recommended mixing the two first in this thread. Credit where credit is due
