    Which are the best black silicone for a 180g + build? Iv never used black silicone, so asking.

    dow corning 995
    momentive rtv 103
    ge scs1200 black

    Iv read that cow corning 995 is used by some public aquariums, is that true? Most of the hobbyist use momentive or ge. So confused. its going to be a high flow tank with back and forth waves, 50+ times the flow. Dont want the tank to burst.. lol.

    I would be surprised if there is a significant difference in the holding strength between any of those products. The key is that you do not want any mold killing additives in the silicone. I would strongly recommend setting up the tank in a safe location (i.e. outside) after you seal it... fill with water and test for a while before use. I had a 220 gallon tank rupture after I had sealed it myself and caused $12,000 in damage to my house. Lesson learned that the trim and center bracing is a key factor in structural support for any tank 75 gallons or larger.
