Is one bottle enough for to seal a 55 gallon tank
Answer by ChewyApr 03, 2018
The amount you'll need depends on how thick you apply the sealant. According to customer reviews, the 10.3 ounce tube worked well for a 55 gallon tank.

Would this work on a 225 gallon fish tank
Answer by ChewyAug 21, 2018
This is suitable for any sized fish tank and is made with same grade of silicone used to seal new aquariums.

How long does it take to dry and does the tank need to be dry?
Answer by ChewyOct 18, 2017
The tank should be completely before use. It takes up to 48 hours for the sealant to dry.

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.

Works perfectly

We repaired a 55 gallon tank that had a horrible leak. We removed the old sealant and used this product. It is holding well and looks good. We haven't populated it with fish yet so can't comment on non-toxicity.

Silicone Sealant

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.

don’t buy this

This smells horrible and is hard to take off fingers and didn’t help with my 5 gallon tank leakage

More than half the tube was solid.

Only a third of my tube was useable. More than half of it was solid. Didn’t have enough to seal my five gallon tank. The seal on the tube wasn’t broken and it was my first time using it the day after it was delivered. Very disappointed!!

Great piece of advice: Always buy more silicone than you think you'll need -- you don't want to run out in the middle of your project! So I bought the big one. This is high quality stuff and I'm so glad I bought the big one. I used it twice to finish a project I had -- resealing a 46 gal tank and then using it a week later to fix the brace of said tank when it broke. The tube seals well if you stick a long screw into the cut top -- that's how I was able to use it twice at two separate times (and I've sealed it again for use later when I need it).

Very Messy

When I tried to use this product, the back of the tube came out and silicone went everywhere. I wound up scraping it out of the tube and putting it in a pastry bag to seal my aquarium. On the upside, it doesn't leak!

New silicone, best one to get!

My dad and I have redone his 250 gallon aquarium twice now! This second time worked like a charm, the speedy service of getting our product from Chewy was amazing, not to mention the color of the silicone was so crystal clear and has worked excellent! The first time we bought a regular brand from a local pet store and it started to leak within a month of us redoing it, keeping our fingers crossed this continues to hold up!
