Careful, all clear silicone is NOT necessarily aquarium safe. If a tube says "not recommended for aquarium use", then avoid it. Most tubes will have this in really small writing somewhere on the tube. I have, in my workshop, a clear "silicone" tube that contains mold inhibitors. There are many polymers added into a mix that can be called silicone, but the type of silicone used for aquaria is the one that indicates "aquarium safe" on the tube and typically has some warning about acetic acid fumes given off during curing.
