water would only appear to acidify.. it would be the small amount of CO2
from the CO2
in the air from the room that would be in it that would make it read a lower then nurtural PH
. The same would hold true with RO
water. A TDS
of 37 seems to be a fairly low number to me.. (going to FW
roots here LOL
) Discus breeders use up to 200 TDS
for spawning purposes so under 50 would seem to be pretty soft to me..
are most likely the bigger concerns.. And the DI
going bad quickly seems to be bit of a misnomer, depending on how much you use(how big your DI
chamber is) it can last 6 months or more..
Ive also seen the DI
only products.. they seem to use a bigger DI
chamber with the same prefilters that a RO
would come with..
