So, to help your mister nozzles you can clean them with vinegar periodically. You can hold a cup of vinegar up until the nozzle is submerged and let it fizz for a while. Periodically I take the tubing off the cage, coiling it all up in the mister bucket, and using the pump cycle vinegar through the whole system, then cycling some 2:10 bleach to warm water through it. rinse until you can't smell the bleach. This kept the mineral deposits down as well as bacteria.
