This is a great thread. I've considered pulling the plug on a controller also, and read multiple threads in which reefers swear by their controller but don't really say why, only that they wouldn't set up a tank without one. Can some of you please continue to explain what exactly you can do with your controller that you weren't previously doing with timers, etc, other than remote monitoring? (I get how getting an email at work would from your Apex if something is wrong would be extremely comforting).
I feel that many of the functions of a controller already exist on my tank and it makes me question whether the money is worth it. For example:
My vortechs are wireless, and they go into feed mode at the touch of a button - either I push a button on my apex or on my vortech, I'm standing right there feeding them so what's the difference? My temp is controlled by my heater setup. My ATO is controlled, well, by my ATO, I'm not sure what you do to "control" an ATO other than make sure the reservoir has water in it. Ditto the skimmer...what do you do to control it? It just runs. Most lights have a built in timer.
I'm not criticizing anyone who spends the money on a controller in any way - in fact it's the opposite. I'm trying to understand how it is value added when it seems that most of the benefits it provides are already intrinsic to the products we buy, and I would love for someone to help me understand because I would LOVE LOVE LOVE to get email alerts if something goes out of whack while I'm away, but I can't justify spending $700 for that
My exact way of thinking before I jumped on the controller wagon. I'll explain some.
For my feed time, I leave my powerheads on, but turn off my skimmer and return pump. I used to do this manually with two switched outlets on a power strip. No, not a big problem. After feeding time I'd turn on my return pump, wait a while, then turn the skimmer back on. Once in a while forgetting to turn the skimmer back on as well. With the controller, one button and they both go off without having to open my stand. Then after a set time the return comes back on automatically and after a set amount of time, so does the skimmer. Easier for me, and for anyone else taking care of my tank as I travel a lot.
For water change times, I also turn off my powerheads as the water gets low enough in the display that they would splash water everywhere. I have a second standby mode that has a time duration setup for how long it takes my typically to drain and refill water, then everything comes back on in time. I also like to turn my heaters off during water changes as I've forgotten to before and while draining the sump had heaters come out of the water. It is NOT recommended. Now I don't even think about it.
Heaters fail ALL THE TIME. They often fail ON. Having an outlet controlled to turn off if a certain temp is reached can be INVALUABLE.
ATO: I had different ATO systems, they all work just fine. Having it integrated into the controller is nice though as stated earlier, I have it programmed to turn off when I'm doing maintenance or feeding. One less switch to flip. I've also added a float and alarm on my ATO reservoir in case I forget to fill it up it won't burn the pump out.
I also have alarms set if say a powerhead for some reason starts to draw too much current. That means that perhaps an urchin or something ate through the wiring and it is leaking electricity into the tank. It will shut off that component.
Things that my controller have replaced:
1. Skimmer delay timer
2. ATO (and improved capability)
3. Heater controller
4. Manual light controls (I use cheapo chinese LEDs that I now ramp up and down with my controller)
5. I've eliminated several power strips and wiring mess in my sump.
6. I now know my PH, temp, etc at a glance.
Yes, as you stated, a lot of this control is available in the individual parts of the tank equipment already. So if you added all the $$ that you would spend on a heater controller, ATO, PH controller, timers, strips, relays, etc, is it really that much of a stretch just to get a controller instead? Yes, the Apex is very nice if you have the $$. You can do everything I use mine for on a controller that is less than $300.
No, a controller is absolutely not needed, but it is really nice to have and once you get one, you will not go back.
