Reefkeeper Lite Question


Bakenn

Recommended Posts

I have a 29 gallon reef tank with a sump and a CPR Over-Flow Box. Can the Reefkeeper Lite control the return pump and the aqua lifter pump that hooks up to the CPR Over-Flow Box and what I mean by this is lets say the aqua lifter stops working, can the Reefkeeper Lite turn off the return pump so the tank does not overflow? Thanks!

In order for the reef keeper to take any action it needs a way to figure out that said action needs to be done.

 

You would, in short, need a way to sense that the aqua lifter was no longer working. I'm not quite sure how you'd do this; the reef keeper does not intrinsically monitor whether everything plugged into it is functioning (can't easily do that from a "how to wire it?" perspective). It only knows if it is providing power to a specific outlet or not.

 

The switch bank that comes with the SL1 provides a lot of ways to set stuff like this up. I have a basement water sensor wired into one of the switches and the logic set up, "if this switch closes, kill the return pump."

 

It is also worth noting that the aqualifter stopping does not immediately cause failure of a CPR-style overflow; it simply allows the buildup of air bubbles which can eventually cause failure of the siphon. I had my aqualifter fail often back before I discovered how easy drilling a tank is, and every time I saw it I'd get it hooked back in and working without any ill effects, right up until the time I didn't get to it in time....which is why I now drill.

the sl1 has 2 'switch' inputs. as it relates to your first question, you would need a float in your display sense that the water has gotten to high, indicating the overflow has failed. then you would need another in the return area to sense that it has gotten to low.

 

maybe im understanding you differently but are you asking if you can put a float in the return area to indicate that the over flow has stopped working? that may work, but i wouldn't think it would be as safe. especially if you decide to run an ato.

Hello Bakenn,

 

You could definitely use the float switches to do something like that. I would check in the digital aquatic forums for exact instructions, (the community of there is awesome), but I think you can set up an "alarm" function. The float switch could trigger this alarm, and then you can have devices respond to the alarm.

 

For example, the float switch would trigger the alarm and then you can have your return pump shut up, the ato turn off, etc. I had a similar set up for a "too full" switch in my display tank. When the switch would trigger, my return pump and ATO pump were set to shut off. I had the net module, so i also received an email in this case and could turn other devices off if needed.

 

I hope this helps.
