tropic marin nano shake and make

[profntbtr]

did anyone else snag the tropic marin nano shake and make container? i have one, but am presented with the challenge of draining to an appropriate level by guesswork. if any of the other people who made it up to Macna are willing to give up their empty bladder, i would greatly appreciate it. i'll pay for it, or can trade a bucket. 2.5 gallons is a better sized water change than the 5 gallon bucket i've been doing.
