urgent silicone question

[fresh]

Hi all,

I would like to reinforce my 72gal bow with silicone, however it has BLACK silicone.

I went to Canadian Tire, Rona, HD, etc, and they all have the SiliconeII in black, but nothing else. The stuff that says "aquarium safe" comes only in clear and white!!!

I have read mixed reviews about SiliconeII (even the window and door siliconeII which is 100% silicone with no mildew preventatives), and I just wanted to know what you all suggest???

Should I just bite the bullet and go to the pet-store to get a $14 tube from King-Ed, or is there another solution?

Thanks in advance.

Fresh.
