Silicone for 200g tank? Momentive vs GE

cromag27 · Sep 4, 2016

His fabricators have never worked with black silicone. that in itself tells me they aren't capable. you're right he can do what he wants. I base my statements off 20+ years in the industry as well as in the constructon and woodworking industries.

That doesn't mean I'm wrong, or that the GE SCS1200 won't work just as well. Was the GE product even available when you were building tanks? When was the last time you evaluated all the silicone adhesives on the market? I also never said his builders knew what they were doing.

I wasn't being accusatory so don't take it that way. I only stopped building tanks a couple years ago and I know GE was making the scs series back then. I've used it for other purposes, but household purposes. I remember reading some of the ssg ( silicone structural glazing) silicones excrete oils. that was enough for me to stick with the tried and true - momentive. there's a reason large tank builders (Lee-Mar, dsa, etc) use(d) it.

All they used is ge, im sure not scs1200. Most of them use momentive abroad, im from india. We have a momentive distributor here, so was plannin on momentive only. Black silicone coz there is always the problem of algae penetration in the white silicone after a few years. I want this tank to like last forever. No leakages.

GE 1 would make sense, but not scs1200. I've never seen white silicone used, just clear and black. never heard of either having a bigger tendency to effect algae. that's a new one to me.

Sorry, clear silicone not white.

From the SCS1200 spec sheet I'm not surprised to see that. It's interesting that aquarium use isn't actually stated on the SCS1200 spec sheet when the SCS1000 says that though.
It sounds like you'd be ok to go with either. Honestly if your builders have a preference for a particular product I would go with that, provided it's one of the products you've already mentioned. There can be some extra risk if you force your builders to go with something they're not used to handling.

Are you 100% sold on glass? From what I can tell many glass aquarium manufacturers warranties are 10 years at the most, but many acrylic aquariums I've looked into are warrantied for life from leaks. Every fish store I've been in has a story about at least one of their glass tanks failing on them. There's obviously a lot of trade-offs regarding maintenance with acrylic. I don't think you can let the tank go for a month and then scrape algae off the walls for example. You have to be careful with cleaning and use specific products and you would have to plan to buff it out every once and a while. Don't buy acrylic if you think you'll never have to deal with scratches. Some pro's for acrylic besides the durability are that it looks clearer and nicer (if you take the care to limit the scratches) and insulates the tank from temperature changes 4x better than glass. It's also lighter and easier to move with only 2 people.

Acrylic is way beyond my budget as its very expensive here in india, id rather go for all-clear glass on all sides. There is momentive available here, but not being able to find scs1200, still will try though.
