I had an Apex Jr. on my last setup and loved it! With gift certs I had I just bought another one for my current system. Haven't set it up yet due to other things going on.
My original Apex Jr. system had the following:
- Apex Jr. module w/temp probe
- VDM
- EB8
- PM1 module w/ another temp probe
- Breakout box
I had it running my 120G DT in my office, the 100G stock tank sump in the basement, 40G breeder and 29G QT tank also in the basement. It handled alternating the power-heads, turning on/off the heaters and lights, ramping up/down the LED lights via the VDM, and running my homemade/DIY auto-top off.
Best money I ever spent running the system.
