I don't currently have a controller, so this would be an awesome acquisition. I would primarily use it as a fail safe. Temp primarily, but the possibilities are amazing.
I like the versatility of the controller. I am a on-the-go person and concise simplicity is what attracts me to the Apex. It makes it easy to accurately manage your dream reef!
A few years ago I almost pulled the trigger on getting a neptune system.... But unfortunately silly things like the mortgage, taxes, wife got in the way (j/k about the mortgage n taxes) so in the end the idea was always put on the back burner....
Would love to win it...I mean who wouldn't.... There is nothing more soothing than having that extra redundancy with your system
1. I'm already the proud owner of an Neptune System Apex Controller on my 45 gallon JBJ AIO system. It's been a major factor in being able to manage my aquarium with long work hours and getting insights in heating and cooling trends as well as pH that you really cannot get with other products. If I got this controller I would essentially use it to monitor a separate quarantine and propagation system in another part of my home. This way I could keep tabs on each of the aquariums individually.
1. Love everything about apex. Already have all tanks in my house controlled with apex, even my quarantine. Love the ease of programming and being about to do it anywhere.
Side note, if I win its getting donated to the Lutz kid museum reef tank.
