Part Numbers Variations: SCS1203 Review: Resealed a 72g Bowfront Aquarium - This stuff works Awesome! I resealed a 72g Bowfront Aquarium that had a leak..I filled up the tank after letting the silicone cure for almost a week..Not one drip! If you need to seal an Aquarium this is definitely the stuff to use. Review: I will take some getting used to working with it but I do like the look - I used this to rebuild an aquarium. I chose SCS 1203 which is black. It seems to be stronger than GE Windows and Doors and might have a slightly longer tooling time, but just an opinion. I will take some getting used to working with it but I do like the look. The only issue is it is a bit more expensive than the GE 1. ## Features - High Modulus, High Strength Silicone - Wide Temperature Use Range - Creates Permanent Watertight Bonds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001G11JE8 | | Best Sellers Rank | #154,458 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #271 in Silicone Adhesives | | Brand Name | C.R.

Silicone caulk will adhere to most things like stone and rock. The key is to make sure the mating surfaces are as clean and grease-free as possible. **Q: Will this hold up to resealing a 850 gallon saltwater aquarium that’s 12’x36”x36”?** A: In my experience this is one of the only products out there which will bond glass to glass. I have used all of the colors and have never had a failure either by shear or pull. Properly prepared surfaces will ensure a good weld, but I would suggest a retention band around the rim and base- thats a lot of water! I have heard rumor that this is the product used in large scale aquarium builds, and I would suggest you call an aquatics center or aquarium to make sure. Hope it helps. **Q: How many tubes will i need to reseal a 125gallon tank?** A: I think you can cover a 125 with three if you were really proficient, but I would get four just in case. The consistency is different than GE I and seems a little more thinner. It has a higher sheer force so it is very good if you are doing a complete rebuild (all glass separated) but if you are just resealing, you could probably get by with GE I. Hope this helps. **Q: How many tubes will be needed for resealing a 33 gallon tank?** A: I have gone several standard 55 gallon tanks with a single tube. You must have a plan because silicone won't adhere to other silicone if it has been more than about 5 minutes. Be sure to start with a perfectly clean glass. I used acetone to wipe it clean just before starting. I only had one tank ever leak and it took almost 5 years. I was a small leak in a smaller tank and I resealed it again. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Resealed a 72g Bowfront Aquarium *by G***0 on December 12, 2018* This stuff works Awesome!
