RO for aquaria
The comment about copper pipes caught my attention in regard
to the RO system. My experience has been that one needs to be very
cautious with copper pipes, particularly if the water is acidic or otherwise
corrosive in some fashion. In my case, I was pleased when I moved to my
present house about four years ago. The pH of my water was 6.1 with
negligible hardness, seemingly perfect for the South American fish I usually
keep. To my dismay, though, I was unable to keep either fish or plants
alive for any period of time. I finally had a test lab check my water, and
they found copper levels of .61 mg/l. That level is not hazardous to
himans, but is well above the .05 to .10 which seems to be the upper limit for
freshwater aquatic life. Apparently, the water is acidic enough that it
causes copper to leach from the pipes. I considered an RO system, but was
concerned about the amount of wastewater generated, since I am also on a
well. (I am always paranoid about it running dry.) As hard as the
writer's water seemed to be, that may not be a problem for him, but it is
something to keep in mind for anyone with copper
pipes.
