Questions & Answers

18 Customer Questions


How long does it take to dry and does the tank need to be dry?

Answer by ChewyApr 02, 2024
We recommend ensuring that the glass is completely dry before applying silicone. If water is trapped between glass before applying, you can use a hair dryer to blow the water out with cool air. Drying times may vary. To ensure a leak-proof seal allow 48 hours before filling the aquarium with water.

Does it just squeeze out or what

Answer by ChewyJul 26, 2021
The sealant may be pushed out by squeezing from the bottom of the small tube. For the larger tube the bottom may be pushed up or a caulking gun may be used.

Will it work on a pond heater - withstand freezing temperatures?

Answer by ChewyFeb 27, 2018
This product remains flexible from -80F to 400F.

Would this be safe to use for my bearded dragon's terrarium background?

Answer by ChewyJun 14, 2021
It is recommended that this silicone sealant be used only for its intended purpose, which is glass aquariums.

After trying to find this item at several pet shops I looked up Chewy and there it was. My 125 gallon tank sprung a leak and all the water drained out killing my fish. Chewy was fast in the delivery with a great price. I told my pet shop about how easy it was to order and they are going to tell customers about how good you are.

Did what we needed

We made a plexiglass window box for our cat and used this to seal it. It did have a strong odor, but it worked really well. I would buy it again.

The contents must have been defective. It was like there was a blockage in the top portion because when we tried to push out the silicone sealant, the bottom popped off and the sealant was all over the "gun" and the counter. I was able to use my finger to put the sealant in the aquarium, but it wasn't a very neat job.
