I built a sump refugium with Silicone I a year ago and although I've seen whole tank builds done with it, it pretty much wiped out all my softies. It definately changed or put something in the water.

Why nOT just buy aquarium safe silicone from the local store, $20 is no big deal when you could potentially lose 100's.

After hearing and seeing the horror stories online, I would not risk it!

Yah I have also decided buying the mariland silicon from Big Al's. Not taking the risk; not worth it to save a few $$.

Because it's ridiculously marked up, it's a small tube and won't do larger jobs, and there are plenty of alternatives.

Well Brad, I get my Aquarium safe silicone tubes for $15 but that's me, everyone else gets theirs at a store for probally around $20, a regular tube is $5 at hd, so really you're saving $15 but is the saving of $15 really worth losing your reef?

I am just sayin, for a cost of a dinner it's not worth the risk at least not for me.

Maybe in Victoria you get toothpaste tubes but here on the mainland we get standard silicone tubes, the size that fits caulking guns.... Again just sayin!

I bought a whole case of 24 tubes SCS 1200 for $116 in Calgary @ Sabic for my 300 build so under $5 a tube.

We do get toothpaste tubes, but for me, the hardware store with safe silicone is closer than the LFS. Like i said, it's readily available. If you're going to the fish store, you might as well go to the hardware store..

There's no risk with GE SCS1200. It's what should be used exclusively, unless you can find a comparable. I haven't found one.

I'm with Grizz. I got mine for around $7-8 per tube of SCS1200 but I only bought a few. People stress over what to get and try to cut corners with GEll when everyone should be using SCS1200.

depends on what they're doing. If you're just adding baffles to a sump, or other small job, regular silicone is more than enough. If you're building a tank, then ya, the 1200 is the stuff to use.

Well Brad maybe we should sticky other reef safe silicones like the one you use and the scs1200 so everyone knows....thanks
