food colour in pond
Hello,
sorry for another "dumb" e-mail but I just read that some people put
blue food colour in the pond as a replacement for the "official" pond
dye. Is this safe ? For a small pond like mine it is certainly cheaper
than buying a massive bottle . I hear that a capful is good
enough for 500 gallons.
ps- colour is spelled C-O-L-O-U-R in Canada
