Mistking all the way. I went through 3 monsoon misters within a year. They actually made me go back to hand misting until I have my rack filled and then I'm installing the big boy Mistking system. They are more adaptable and since they use a diaphragm pump, no worries about something happening and it running dry. It will survive.
As far as how long to mist, only you can answer that by experimenting and watching your parameters. Every tank is different, so there's no set pattern.
