Dumb question about water

[Funky_Fish14]

I store 100g of R/O water at a time. The longest it gets to sit for though without use is about 5-6 days. I have 0 growth of anything in my bins (40+60g).

I use a polyethelyne bin from a plastics company. Big white thick-walled plastic bins. Hit'em with a hammer full of water or not and they wont break. I've had 2 of 4 rubbermade trash cans leak (although slowly) without even being stressed.

Cheers,

Chris
