I won one of the 13Q coolers a few months ago. I'm looking forward to having time to go use it. The full net will make water changes easy. I have a bottle of ammonia remover for fish tanks that I keep in my old minnow bucket that I am going to move to this new cooler. Its handy if you have to go a few days without changing the water to just add 1-2 drops to help keep them alive longer.
