Please log in for more thread options Hello!
My job needed me to go on the road for a week awaw. During that time the
house lost power, by the time I heard about it the tank had been without
water circulation (manual siphon didn't restart) for 24hrs. In that
short time I lost three peppermint shrimp, a pseudochromis, and a
Hawaiian yellow tang. I walked my wife through the startup procedure
over the phone and she was able to get the tank restarted.
Now, I'm looking to replace the manual siphon with something that will
automatically restart after a power failure (suggestions welcome) but
wanted to mention that it was very surprising to me that the 02 level
would drop so quickly with such a small bio load. I have other
freshwater tanks an a couple years ago we lost power for two weeks.
These tanks have heavy bio loads and other than loosing the plants (no
light) the fish seems to do fine for the 14-days without supplemental 02.
Is this common with marine tanks? Is the 02 requirement higher due to
live rock and the other critters? I ran the usual tests today and the
tanks chemistry is stable. I have no way to test for dissolved oxygen.
Thanks,
mark h

There are test kits for oxygen, but I'm sure yours is fine
now. Yes marine tanks with live rock, will drop in oxygen
quickly. 8 hours is ususaly ok, 24 hours will usualy kill
a good number of fish and shrimp.

Please log in for more thread options And also even without live rock, salt water fish are more
sensitive to this than fresh water fish.

Please log in for more thread options Have you see the Continuous Siphon Overflows on Drfostersmith.com ?
http://www.drsfostersmith.com/Product/Prod_Display.cfm?pcatid=3642&Ntt=overflow&Ntk=All&Ntx=mode+matchallpartial&Np=1&N=2004&Nty=1
They use a Aqua Lifter Diaphragm pump to get it going again.
You can buy them for around $10...
Or change your overflow to the kind that use the u-tubes...they baffle them
at each end so the water never leaves
the tubes and suction starts again when the power returns.
