If aeration is a problem, one could get one of those aerators fishermen use, powered by D-cell batteries, and a bag of alkaline D-cell batteries. There is a “Bubble Box” (brand) aerator that is claimed to run up to 44 hours off a couple batteries. If not quite as strong aeration is needed, one can run off one battery at a time, and may be able to stretch the usage per battery out further. (Disclaimer: I do NOT know how the current draw varies with 1 batt vs. 2.)
Some of the rechargeable batteries have greater storage capacity than alkalines*, but you don’t have time to get such and charge them, I’d say! Much less a way to recharge them once power goes out.
*I have tested some D-cell NiMh batteries at well over 7000 mAh capacity.
However... At this point, you’ll be lucky to find any batteries in the stores, I’m afraid...
Thanks for the heads up, as not aware off that product.
A Coworker lost all her koi last hurricane, due to power outage. As long as I have water pressure I plan on just running the hose to aerate.
And yeah, it’s too late to be on the road. I can already hear the sirens.
