Planning for a scheduled power outage

[cwatkins]

We got a slip on the doorstep from BC Hydro the other day about a planned 6 hour power outage for our neighbourhood next week.

I already have 2x MP40's that run off of an Ecotech backup battery system, so water movement is going to be OK during the outage.

I'm just wondering about temperature and oxygen.

I figured it's summer, so the temperature should be stable. It's not hot around here lately anyways.

As for oxygen, would 6 hours be ok without added oxygen other than surface exchange (water movement from MP40's mid-level in the tank).

Or should I look for one of those battery powered hand held airpumps with an airstone? They last 72 hours or so?

If anyone knows where to get one in Metro Vancouver. JL no longer lists them on their website, and OA is out of stock.

The trick here is I'm not going to be home for the outage, so I'd have to turn on the battery backup airpump the day before.

Thanks.
