sily kone

I have used both, and have never seen a problem. But there's always a risk if you get something that's not tested to be safe in aquaria.
 
I was wanting to enlarge the sump in my tank (while I have it emptied) to house my skimmer, I was going to put a small sump on the opposite side to house power heads (keep them hidden). I was going to run to home depot, and pick up some regular silicone if it will work without harm. Will a regular silicone bottle say something about aquaruim safe? What type did you use?
