I'm currently setting up my 10 gal hospital tank and I went out of town for the weekend. I didn't anticipate water evaporation to occur so fast. My SG shot up to about 1.03. So I'm wondering if I need to buy a little more live rock or not. Thanks again.

I did siphon off a lot of detritus or something of the sort after my SG shot up. I don't know if it was because the rock was still curing or if I killed it. And could you explain "cooking" rocks please.

SG of 1.030 won't cause any significant die-off...if any at all.
Cooking live rocks is when you place them into a dark container with normal salinity saltwater, a heater at normal temp, and a good powerhead for circulation. You do weekly 100% waterchanges, and swish the rocks around during the waterchange to remove all the detritus as it falls off. You keep doing this until you get a Phosphate reading of 0. This is usually done with rock that is suspected to be leaching phosphates into the water. Tanks that are having severe algae issues are prime suspects. I also do this with any new LR - cured or uncured. I figure what's the point of introducing phosphates to the tank when you can get rid of them in the first place?
