Sorry Bob K, didn't realize you were the expert about keeping fish...

I bow to your oh-so-ever-abundant-knowledge....

Often, hot water heaters have more metals in them and some of them can,
not
always, but can get into the water... I've only heard of iron(which may
or
may not be bad) can come in the water from the hot water heater... but I
was
told that by a reefer, so whether it has any bearing on FW tanks, I can't
say...

Calcium can be another story in and of itself....

Oh my gosh.. Nearly 50 years of doing the wrong thing..
Will my fish ever forgive me?

Oh.. wait, you were TOLD that .. Ahha, was that a
goldfish keeper?
