Aquarium Controllers
 

Hi everyone,

Like almost everyone in this hobby I would like to explore ways to improve my tank and wondering exactly how people are using their Reef Controllers and the benefits from using them.

I currently do not have one but everything I use seems to be pretty well automated on its own for example, Lights have built in timer, Power Heads have controller, 2 Heaters so if one stops working the other picks up the slack, ATO fuctions with float switches, and my feeder has a built in timer and I test the salinity of the tank fairly often but with a larger tank it seems to always be within range.
From what I have read the best benefit for me would be with the PH probe but to spend the amount of money required to pick up a reef keeper I am not sure the benefit is there.

I guess I could save a little money by having it turn on fans when the temperature reaches a certain point rather than running the fans all day?

Maybe, you all can give me some ideas for the uses and some input on more of the benefits I would see from using one.

Thanks for any input

Heaters can get stuck in the on position this is one of the great benefits of a controller the controller will simply cut off power to heater. also if your tank gets to hot the controller can turn things like lights off. There's many benefits of a controller.

Before I had a controller, electrical plugs and timers were getting totally out of hand. Now I control everything, lights, pumps, dosers, chiller,skimmers, heaters, ATO, etc with the controller. Allows me to program in a lot of automation, safety, redundancy, convenience and transparency which I didn't have before.

For example, if I have a power outage, my skimmer will come on 5 min after my return pump, when the sump level is back to its normal level thus preventing skimmer overflow. If I have a leak or overflow somewhere, it can automatically shut down a pump, and alerts me, so I don't have a water flood disaster. Many, many things you can do with a controller...

I am often away from home, and the controller gives me more peace of mind, too, as I can monitor and makes changes remotely through the internet.

You mention PH monitoring with the controller. I have the probe, but don't even use it, as that is least benefit, IMO.

There are good threads on RC, which should give you a better understanding of what can be done with a controller.

I use a Finnex temp controller I don't want to just depend on the on board mechanical control i've had them fail too many times, now my water temperature stays spot on @78 f.
+1 to using controllers :smile:

Mine saved the day a couple of times now:

a) Got a notification that a runaway heater was determined to
cook my fish! I caught the unit while the water was at 28C.

b) Got a notification one day that my ATO system was overly "enthusiastic"
and my sump was close to overflowing. Being away for 3 weeks, I had to
coordinate a fix by phone with my tank sitter but early detection was key.
It saved my tank & vacation!

^ would hope a controller wouldn't allow these type things to happen to begin with.

Ran my tank with a PLC, used it to controller temp through heaters or fans (evap cooling) and for a bit CO2 based on a reactor's effluent, then a doser.

I agree however in both cases, the sensors had failed (wire issue and
a stuck float). The nice thing is that a secondary temperature sensor
and float were wired to the alarms of the controller. You could say that
I have a new found respect for redundancy :)

I have a reefkeeperI also currently dont run an ATO.
I only have my skimmer, return pump and 2 heaters plugged into my controller.
powerheads and lights have their own controllers and the switch from MH to LED opened 3 additional outlets up so when I get around to it im going to use them to make WC and top off pumps run. not automatic but just so I hit a button and pump starts hit it again pump stops. with a ball valve that needs to be open first before it can go to the display. I just dont like the idea of cheep float swtiches connecting a 55gal drum of freshwater to my DT.

Now with so much equiptment have their own controllers (powerheads, DC pumps, LEDs, dosers ) I question whether a controller is necessary any more for me but I have it so Im going to continue to use it.
In my case Ill never run an ATO so all the float switches and alarms dont benifit me, no ca reactor so i havent checked my ph probe in years, house has central air so a chiller isnt required, so a $50 ranco heater a $10 digital thermometer controller and a couple of manual switched outlets so for roughly $75 I have almost the same thing 4-600 controller for how mine is used. but this is no where near the capibilities of the controller either.

A good controller is also almost endless in what you can do with it as well.
reduncy for auto top off
reduncy for heaters
stabile heat and cooling
automatic water changes
every safety feature you could possibly come up with.
time delays on outlets.
MH safety ( time delay start ups, lights off if tank reaches certain temp.)


they are a very nice piece of equiptment to have and a necessity if you run ATO chillers, MH lights, any non programmable light reallyjjust to ditch 3-5 manual timers, ca reactor, if you want an auto WC system.

Here is my response to the same basic question that was in a different thread a couple of months ago.
