Trojan Man~I'm a big fan of the saying "Better safe than sorry".
Whiskey
I feel your pain reefnut......I'm very thankful that most of my life I've been left with gallons of water that I wouldn't normally purchase...still drinking last season's supply...and it tastes awful...which makes me think if I can't stand the taste...how must my poor fishies feel having to live in this junk? I'd just use it to water plants and save the jugs to fill with ro/di water next season.
