What silicon can I use on my sump?

[rdefino]

I'm building my wet/dry using a 75bal and some acrylic sheets as dividers. What silicon can I use. Anything that would be sold any Lowe's or Home dept?

Off hand, how many bio balls would be good for the sump? I have a 210 tank. I any ready have 5gal of bio balls.


Thanks

GE type 1 100% silicone without mildew resistance will work, and rather than buying more bioballs get some nylon pot scrubbers and mix them together (it's cheaper and more effective).
