Good to know. My 3155 has been super reliable. I'm preparing for 15-days of my tank being fully automated with no human interaction.... so whenever I read these equipment failure posts I get slightly nervous.Yes to be fair I did buy it used. Also this probably isn’t great underwater.b
I'm setting up 3x ATO's and i think (big maybe) that just 2 of them would be enough for 14-15 days considering the extra day or so I would get with no topoff before my Return Pump starts blowing bubbles.
I'm setting up:
1x Tunze 3155 in the usual 7-gallon ATO reservoir I always use in my sump
1x Dosing Pump 50ml per minute which I think I'm going to go with 100ml every hour in a 14-gallon bin which I'll probably put 12-gallons in.
1x Tunze 3155 in another 14-gallon bin which I'll put another 12-gallons in.
I setup a camera so I can see all 3 of the ATO reservoirs and if my return pump is working properly. I setup a backup return pump plumbed to a coupler which can be easily swapped out in the extremely rare event of my new Eheim AC pump stopping. I'd have to find a neighbor or family member to swap them out.
I even bought a backup Auto Feeder to keep the PO3/NO3 stable, in the even that an auto feeder dies...oh yeah and feed the fish too. I normally use 1 feeder to feed twice per day. My plan is to use both feeders and have them feed once per day.
I'll leave the AC on in the house and I have 2x fans programmed into the APEX. 2x Heaters too, but probably won't need those.
Can anybody think of anything I'm missing?
