tons of carbon, 50% water changes for a few days and poly-pad if you have it. if it is in your sump take the sump off-line, home the heaters to the display and put in an air pump.
personally I would scrape the new silicone out, clean with rubbing alchahol and redo with the right silicone. I like the RTV-108 from GE. used it to replace the side glass on my 40 gallon breeder sump and put in 3 glass baffles with it.
hang in there!
