1/2 HP Penguin Chiller
I received my chiller on time and the set up was easy. I will say that Plunge Junkies answered all my questions quickly---until I purchased the unit--then crickets. So I would say I am not sure how any follow up will go. But for now allmis good.
1/2HP Penguin Chiller
Fantastic unit. Upgraded from a 1/3hp aqua to this for my 100 gallon stock tank and couldn't be happier. Easily hits my desired temp of 45 and might start plunging at 40 now cause, hell why not? Ya'll need hats or shirts cause I freaking love your website name.
