On a whim I decided to test the TDS
level on the RO
water I recently bought from my "trusted" lfs
. I was floored when it read 482 ppm
!!! I thought perhaps my meter was malfunctioning, however when I tested my well water it was in the typical range it has been, which averages 64. When I tested some distilled water I had bought in a gallon jug from the grocery store it read 0ppm. I had some "RO
" water left over in another container that I had purchased from the same lfs
a week earlier and it read 84ppm. So it appears that my lfs
owner is obviously ripping me off, but any reason for such a fluctuation? 482ppm one week and 84ppm the next??
Also, I typically do not use prime on RO
water when I do water changes. If this was actually city water, wouldn't the chlorine and other additives affect my corals and fish? I don't see any issues today.
Not only am I furious, I'm confused. I have every intention on confronting this person.
At least now I know the main source of my algae issue. I wonder how often this goes on.
