Floating SG/temperture gauge

[thincat]

Okay just a heads up so you don't make the same mistake. I had (notice past tense) flowing around in my sump. More so just to get a temp. reading just cross check with my controller. Well it broke and all of that mercury flowed into my tank. Every thing closed up. When I saw that I did a reading of all my water parameters and got ammonia 0, nitrite 0, SG 1.025, nitrates 0. I said "Oh heck" haha and did a hugh 50% water change since I had the water already made up and all was stable, Temp, ect...
That was yesterday...Today everything looks a good as ever...Be careful if you have one of these.

i had the same thing happen. as a matter of fact, i never knew it, but found out when i saw a zillion of those little steel balls attached to a magnet on a koralia. i was thinking the koralia magnet was rusting somehow, but under scrutiny, i realized it was those little steel balls at the bottom of the glass tube. it never hurt anything though.

There is no mecury in the thermometer...it's alcohol.

Wow, what do you think made my animals clamp up?

Hmmm.... I do this very thing... keep a floating SG/thermometer in my sump bubble trap... no idea why - other than to use to double check the accuracy of my digital thermometer. Im going to go take it out now.

i don't think that's a bad thing idaho. i think there is nothing as accurate.

I just use to spot check and never leave it in the tank. Just so it doesn't break. They are not meant to be kept long term in a tank.
