Well yes I DO care how it got there.. I'm just tired...
I guess I'll take a look at the DI canister.. Though if I'm running phosban shouldn't that take care of phosphates?
And that isn't the only thing that cyano eats is it?

phosban can not remove it if your cyano removes it first.

do you have a TDS meter? if so, what is the TDS of your RO water?

have you tested your RO water for "nasties"

so far, all i've seen is that "there should not be any" but no proof that there aren't.
