How to Choose the Best Aquarium Silicone Clear
In this buying guide, we provide you with the following factors.
Quantity
A little goes a long way when it comes to clear silicone. That is why most silicone sealants come in pretty small tubes. What we have to say about this is that if you are not sure about how the sealant you are buying works, go for a small tube. This will spare you unnecessary frustrations in the unfortunate event that the silicone fails to work as imagined.
Waterproof & Weatherproof
Make sure the clear silicone sealant you are set to buy is high strength. A high-strength silicone sealant is always waterproof, and, therefore, works effectively in stopping leaks. It is also weatherproof, and this means it will not dry out, shrink, or crack when exposed to elements. It gives a permanent seal, which is very important when repairing an aquarium.
Safety
Not all clear silicone sealants are safe. So, before you buy one, make sure it meets the necessary certifications and standards for safety and quality. That is to say, your silicone sealant should be non-toxic and safe for fish, plants, and other marine life.
