Just wanted to know what you guys do with the water in the cooler box . Do you guys drain it all after the race, do you leave it in till the next event. I left mine in there for about 2 weeks, holy shit , it stunk like somebody died. I added about a half galon of bleach to it. Kills the algee too. Just wondering if i should add something to it if i leave the water in, I was concerned if i drain it, the pump seals would dri out? Thanks in advance!
