Since I got the basic package for the Apex I'll be adding to it a little bit over time. So, for a while I'm using both the reef keeper along side with the apex as I get new modules. First thing I did was get a break out box to hook up my float switch that's in the back external overflow of my display tank. If for some super remote odd reason my bean animal drain setup plugs up and the return keeps going I have a float switch hanging there to shut it off. This would have to be some very extreme situation that has caused the main siphon to plug up, the open channel to plug up, AND the emergency drain to plug up. NOT likely at all.
Since I have the "brain" under the display tank cabinet to start with I wanted to try out Neptune's new AFS which looks like it's a re-branded and modified Lifegard Intelli-Feed Aquarium Fish Feeder. This will replace my current Eheim automatic fish feeder. The Eheim works great and has been reliable over the years. I feed a mix of NLS marine and algae based pellets 3x per day during the day and then at night I feed some kind of meaty foods. The problem is if I don't turn off my return pump a lot of the food gets sucked down to the sump which I don't mind some of it getting down there in fact I like that but not the majority of it. So, with the eheim it's battery powered and that poses a sync issue with the RKL I had controlling the return pump. The time periodically drifts on the Eheim and I have to check it every month and adjust as needed.
So, that's where the AFS comes in as it will be connected and powered natively via the aquabus like all other modules connected to the Apex. There are 2 big complaints though that many people have with the AFS and correspondingly the same 2 main complaints with the Lifegard. Which are that it's very loud and that people can't seem to get the food amount adjusted right or it doesn't feed the same amount consistently often giving to much food. Both are not concerns to me. Shutting down my return pump creates a good loud sucking noise until the siphon breaks and I feed to much already and would rather have that then not enough allowing some left over food to get sucked down to the sump.
Otherwise, I do like the design of the AFS/Lifegard. For one I won't have to change out batteries anymore which I do once a year on the Eheim even if I don't have to just to make sure like changing batteries out on the smoke detector. I'm hoping it's moisture control works as it extends out to feed and retracts back in to seal it off (which is the noisy part). Time will tell on this but didn't see any major complaints by people on that so must work some what. The Eheim if I really fill it up with food gets clumped up by the end from moisture. There's a little tiny fan on the back that runs every time it feeds to help but just isn't enough eventually. I really like that I can now track when it feeds and can track that it happened. I have had in the past the Eheim not work properly when the batteries do go down. Even though I put new batteries in doesn't mean they are good batteries for long. Over the years I've had bad batches of batteries that didn't last very long.
I set this up Monday and so far so good. To be up front about it one of the main issues with noise is justified. It is not quite at all so if that's a big concern I would not recommend this unit. Otherwise it's not any noisier then my return siphoning out. The feed adjustment to me was fine. Two notches in and seems about the same as what I was feeding with the Eheim. If it decides to feed more periodically I'm fine with that but I wont know except on the weekends and even then I don't watch it except the times I happen to catch it.
The programming was fairly simple. I setup a virtual outlet to do the timing and based on the virtual outlet shutdown the return pump, 1 minute 30 seconds later turn on the feed for a single rotation, and then 45 minutes later turn back on the return pump. Right now I have an extension cord run from under my tank plugged into the EB8 that runs down to the basement sump that the RKL plugs into. So, when it shutsdown the return outlet it turns off everything down there. Eventually I'll be able to extend an aqubus cable to another EB8 and other modules down there and have better controls. Like I really just want to turn off the return and skimmer but leave everything else running. But this will be fine for now.
So the programming:
Virtual Outlet:
vfeed_A8
Set OFF
Fallback OFF
If Time 12:00 to 12:01 Then ON
If Time 16:00 to 16:01 Then ON
If Time 20:00 to 20:01 Then ON
If FeedA 000 Then ON
Return Pump (and everything in the sump for now)
Return_3_3
Fallback ON
Set ON
If Outlet vfeed_A8 = ON Then OFF
Defer 045:00 Then ON
If DT_Sw1 OPEN Then OFF
Skimmer(eventually will go off with the return)
Fallback OFF
Set ON
If Outlet vfeed_A8 = ON Then OFF
Defer 050:00 Then ON
Then some switch logic here too
AFS feeder
Set OFF
Fallback OFF
If Outlet vfeed_A8 = ON Then ON
Defer 001:30 Then ON
