Sugar water for feeding

[javah]

I made about  4 gallons of sugar water in a aluminum pot and
It is starting to grow mold. What do I need to store it in so that it does not do this

Thanks for any help

freeze it.  you can use jars or ziploc freezer bags.  if you use a solid container, leave the lid loose until the syrup is frozen.  if you use bags, put them where they won't be punctured.

Or don't make so much at a time.

.
Add so much sugar as it melts. High sugar content stops mold growing.
You may it it again near boiling. It kills mold and then add sugar up to 70%.
