RD3 80 watt and feed mode
I was thinking about adding a cheap controller ( Reef Keeper Lite) to my system, mostly just to add a feed mode.
I use the RD3 80watt as my return pump. Any reason why I shouldn't? Not looking for a debate on the feed mode. |
As you know, the RD3 80 doesn’t have a built in feed mode. Using a controller to shut the pump off daily which is similar to unplugging the pump for feeding is certainly an option but considering that the RD3 is an electronic device with a computer like controller and unlike a typical AC powered up, electronic devices typically are more sensitive to inrush currents and being powered on and off constantly. My best analogy since I am in the computer manufacturing business is this. Think of it like a computer. If you leave your computer running 24/7 it’s much less likely to fail than if you turn it on and off every day. Most failures happen when being powered back on and my fear would be that cutting the power to the RD3 every day could potentially increase the risk of premature failure.
While I am not a fan of using feed modes on return pumps because they increase the sump levels which can cause skimmers to overflow and also because the return can help distribute food throughout the tank to the fish and coral, if feed mode on a return pump is a necessity, the better solution would be to use 0-10v control to slow the pump down. That would however require a controller with 0-10v capabilities. |

I would think a higher end pump such as this could take it. Having been a heavy feeder the last decade or so, and having recently re-started my 240 ( with lots of bare rock ), I plan on cutting back the amount of food I put in the tank, and I want it to stay there. It does no good in the sump. I have plenty of other flow in the tank ( 48x) so the return pump isn't needed for flow. I am not worried about the rise of the sump/skimmer etc. Got that covered. Having successfully stayed away from controllers over the years, what controller would have the 0-10v feature? |

As for 0-10v control, Apex & Profilux are two controllers that come to mind that have feed mode and are supported by the RD3. The RD3 80 also requires an additional 0-10v interface which can be purchased from our website. You also need to have the 0-10v capable RD3 which is easy to identify as it has a tiny little din connection with a black cap on it located between the power cable and pump cable on the RD3’s controller. |
Reef Keeper has a 0-10v connection on it too.
