Help! Battery operated themometer fell into the tank

danskim · 07/26/2006, 09:30 AM

It seems I'm always asking questions here on the chemistry forum. Thanks to all who have helped me in the past (i.e. Randy

)

Last night everything was fine. I laid the battery operated thermometer on top of the sump and went to bed.
This morning, I wanted to check the temperature and noticed it wasn't where I had placed it. Upon further investigation, I found it INSIDE the water. I estimate about 8 hours may have passed (at most).

I opened up the back case, and a thick red layer of rust was on the battery. How bad is this for my aquarium? I suspect that it is very bad. Currently I only have 3 fish and a few LPS corals in there with all the live rock.

I would not worry but run some carbon to be safe.

Alright thanks. Will do.
Total water volume is approx 165g at the moment.

Would maybe extra skimming help as well?

I don't think you need to go that far
