Product Questions

I'm wanting to install an overflow in an established aquarium. I can drain the water below the level where the overflow will be. How long before I can fill the tank back up without the possibility of chemical leaching and damaging the silicone seal.
Question by: Caleb on Apr 17, 2016 10:12:00 AM
Great question!
It would be quite risky to attempt on a full system. The silicone should set within 48 hours for the curing process. Feel free to let us know if you have any further questions!

Whats the difference between this sealant and your adhesive 10 ounce? Which would be better for adding baffles to my sump and attaching a overflow box?
Question by: Nick on Jan 1, 2017 12:11:00 PM
Great question! Either type of silicone will work just fine for your applications. I personally like the black silicone and used it for my frag tank's overflow box and I also touched up some sump baffles. :-)

  • good product but why $3 mark up? By Benjamin on 1/5/2017

    The stuff works as it should. I don't like that BRS charges $3 more compared to my local big box hardware store.
  • Fixed my leak and is holds great By James on 2/21/2016

    I was an idiot in drilling my tank, but this stuff holds great and seals very quickly. Only complaint is that i ruptured the tube by squeezing too hard apparently.
  • Great Quality By Cody on 4/26/2015

    Used this on a custom plumbing mod on my refugium, worked like a charm. Dries faster than expected, strongly recommend using on dry surfaces as the instructions indicate.
  • easy, convenient safe By Ivan on 8/26/2014

    this is a great product to throw in your order and save a trip to the store. its fish safe, great nozzle for fine work.
  • Good Value By Chris on 2/17/2012

    I like the smaller tubes like this as you don't have to worry about it all hardening up. Would advise if you are building a tank though to get a larger amount as this could become much more expensive to use on real big jobs
  • Holds Strong By Daniel on 11/12/2011

    I used this silicone to put baffles in my sump. I haven't had one leak and only had to use one tube for all four baffles that were each approximately 12"x8".
  • Negative By Weird on 7/1/2011

    Why would you mark it up $2
    This supposed to be wholesale at least prices ... good product
