Unfortunatly black silicone is not sronger than clear..Thats a myth. Clear silicone grows algae quicker on it and around it..More light transferance i believe..when you start to see the algae getting under the bead in your tank keep an eye on it...when it works into the seal between the two panes then its time for a re-seal. Black silicone looks better because it helps to hide algae growth. Also depends on what you like. They both have the same strength.
