Hello everyone ,
I'm planing on getting a controller my system is really small so I don't think I need a deluxe controller.
Now the question is Apex Jr.. Or a reef keeper ?
I love my apex, I have the apex full with a good bit of add ons. If your system is small a Jr will do the job. But if you can afford it I would at least try to find a used full. Just for the simple fact that if one day down the road you want to upgrade to a bigger tank the controller will be able to grow with you. As opposed to having to sell the Jr because you ran out of module space.
