Backup Equipment - What is yours?

[backbayreef]

I have the following as backups: return pump, wavemaker, heater, skimmer, salt, and RODI (275g). Both my main and backup tanks have a DIY battery backup that can run one MP40 for 40+ hrs. Both tanks are running with similar parameters so worst-case scenario, I can evacuate corals & fish from one to another (space permitting tho).

I have:
2 tanks.
Both display.
If something goes wrong with one.
Wish and corals go to other.
It's a good system... I think.

I keep back up bandaides antibiotic ointment duct tape. When working with lr I've always finished with my fingers or hands bleeding. It's never a completed project if I didn't deposit a couple drops of blood. Corals don't seem to mind

Reviving this thread..

I never kept stuff on hand as I always figured my tank can survive without a sump for a bit while I order replacements.

Well I use a jeabo return pump and I noticed it is slowly going out of stock/low stock. I ended up grabbing an extra return pump (slightly smaller as they were out of mine already) and some wavemakers to store away just in case since these items may see steep price increases or be difficult to get for awhile.
