I’ve been pondering every possible disaster scenario as I’m collecting all the necessary components to set up a new Nuvo 40 AIO tank.
My last (and first) tank was an Aqueon 150. It was great, but when things went wrong, there’s a lot of water to worry about. Unfortunately, I sent a few gallons of water through my apartment floor and into the neighbors more than once.
For the new tank, I’ve decided to go with an AIO. The thinking here is that, save for a catastrophic failure, it should be the least complicated - and hopefully safest - option. No external sumps, no HOB skimmers, less chance for water leaving the aquarium.
Here’s the caveat: the tank came with a new Tunze 3152 nano ATO. While I know the redundancy with the 3155’s optical sensor + float switch is safer, this was free. My ultimate plan is to get an apex and limit the amount of time that ATO can be on; safeguarding against it getting stuck on “on”.
I’m wondering if there’s anything I’m forgetting? Any other tips/tricks/redundancies I can throw in to make this tank as spill-proof as possible?
Thanks!
