I was just over stocked for the amount of back up air I had.

Certainly didn't help... as the greater numbers of fish would have exhausted any DO that much faster....

But the batteries couldn't have lasted anywhere near the 5 hours IMO... especially if the pump was producing almost as much air under battery as in normal operation....

I reckon it would have taken an hour to exhaust the DO once the battery backup failed...

I suspect that they didn't last more than 3-4 hours...

Talk to EB... I think they now stock the Aquapro two outlet.. which delivers way more air... has a 6v rechargeable battery... and outputs almost as much air under battery conditions as under mains power...

Battery is good for about 10 hours... double that if you select the "intermittant" mode...



I thought they lasted for 10 hours? , you could be right as I didn't check on them in the last couple of hours

Rupert's comments got me thinking about my recent fish kill and if maybe my battery back up airpump didn't perform as stated on the package (10 hours on DC minimum) and its failure after 4 hours of a 5 hour blackout was the cause of my fish death so I decided to test it out yesterday.

Happy to report that turned up full bore the BYAP 6V battery back up air pump was still going 11 hours after turning the mains power off and still at a rate that the air bubbles were only just slightly less then under mains power. :cheers:

Over all a good little battery back up and I recommend them :thumbright: , I just needed 3 more for the number of fish I had :upset: happy to report that about 10 medium SP survived the massacre :flower: and are looking very scared in that big old FT by them selves

Hi Marc, I would have lost about 150 fish ranging from 280mm to 70mm, I will be getting more fish but not until I have moved my FT to accommodate my system redesign.
