I use the Puhoi plastic milk bottles filled with sea water, they are quite square and stack reasonably well.. I seem to get plenty of spaces with coke bottles. I use a blue and green cap system, the green cap signifies salt water, the blue caps are fresh water which i can drink... Apparently salt ice has a much lower salt content than sea water hence the sea water which should last longer ?
