I just bought another used 55 gal tank because it came with a really nice stand and canopy. The price was right. I lady I got it from said all her fish died all of a sudden but she had not done any water changes in a while. As I was cleaning out the crushed coral to give it a good cleaning. I found a broken thermomiter. The part with the red stuff in it however is broke at the top but there was no hole and I dont think any leaked out. It looks like one of the ones that float in the tank. What is the stuff on the bottom of them its black looks like mercury but I am not sure. Provided I clean this tank really well is it safe to use. I was going to give the other 55 gal to my brother so he can start a swf tank. Also it came with a skimmer it is a aquac urchin. Dose anyone have this and is it better than the seaclone 150 that I have for the other tank.
