I buy my RO
from my LFS
. I had my own RO
unit when I had a tank a couple of years ago, but that was one thing that put me off TBH. Having it running all night in the bath etc., I told myself this time I'd just go to the LFS
and buy it ready done.
BUT, my LFS
isn't nextdoor, so going every week (or even two) isn't feasible. I was told up to 6 weeks would be ok, as long as it's aerated 24 hours before use, but it looks like most are saying that's too long? It always smells absolutely fine, I stick my nose in the container each and every time I take some out to mix, and it smells fine.
I did check the nitrates of the new RO
today at the LFS
, and they were 0. So I guess I'll test them in a couple of weeks to see if anything's changed.
The guy did tell me something very odd though, that he's had his reef for 5 years and just uses (soft) water straight out of his tap, not even conditioned/dechlorinated! Not RO
, just tapwater! Says he's never had any problems, not even any algae. He also believes that LR
is 90% of peoples' algae problems. Strange...
