Home aquariums and fish tanks have gained immense popularity, with people exploring different options to light up the ambience of their living rooms.
Not only does a fish tank looks good, but the aquatic life living in the fish tank is a treat to watch.
However, an aquarium should not be bought just for fun, as it requires commitment, and by commitment, we mean maintaining the aquarium to retain its structural integrity and ensure that it’s a safe haven for marine life inside.
One of the most important aspects of fish tank maintenance that should not be overlooked is silicone.
Over time, an aquarium tends to loosen its structural integrity which is intact through the silicone of the fish tank. Whether you’re buying a new aquarium or you’re looking to make your existing one stronger, you need to buy a solid safe silicone for your fish tank.
What is Aquarium Safe Silicone?
All aquariums need maintenance and a crucial part of maintenance is to make sure that there is no leakage in the fish tank.
Leakage is prevented and countered by aquarium-safe silicone that binds the entire structure of an aquarium together, making sure that it does not collapse.
Hence, an aquarium-safe silicone is a sealant for a fish tank that makes sure that your fish tank is tied together in place, without any leakage or gaps.
How is Aquarium Safe Silicone Better?
Aquarium sealants like safe silicone are the best way to prevent and avoid leakage in your aquarium or fish tank.
The reason why aquarium safe silicone is the best option for binding the fish tank is because:
- Aquarium Safe silicone is saltwater and freshwater compatible
- Contain a specifically engineered formula that is designed to last under constant water submersion for an indefinite period of time.
- Aquarium Safe silicone is 100% safe and made from non-toxic materials ideal for aquatic life or marine habitat.
- Is designed to bind and hold the aquarium together like no other material.
How To Apply Aquarium Safe Silicone?
If you witness a leakage in your aquarium or fish tank and you want to repair your aquarium using aquarium safe silicone, then you need to follow certain steps to ensure applicative success.
It is also advised that you make sure to check other elements of your fish tank, making sure that the problem is only related to silicone application and not any other.
Here’s how you can apply aquarium safe silicone to your fish tank:
- Deplete your fish tank of water – First, you need to empty your fish tank and ensure that there’s no water left inside the tank, before starting off with the Aquarium Safe Silicone application
- Eradicate and strip previous silicone or sealant – the next step you’d want to perform is to remove the previous Application of sealant or silicone from your fish tank to make sure that the fish tank is free from residue or materials for the perfect application.
- Cleaning all Joints – after that, you need to check for rusty or dirty bolts to prevent any kind of obtrusion. Make sure to check for any bad joints and ensure that the joints are clean and held tightly.
- Apply Application (Inside) – this is where you’ll start with the application of the aquarium safe silicone, after following previous steps. However, don’t follow an unstructured manner, start applying the aquarium safe silicone from the inside of the fish tank first, and then make your way through all the corners. Make sure that there’s no gap that remains inside. After you’re done, you may want to hold for a few seconds to let the sealant dry.
- Apply Application (Outside) – once the inside application is done and the aquarium safe silicone has dried off, start applying the aquarium safe silicone from the outside, in a similar manner to that of the inside application. Again, make sure that there are no gaps or empty spaces and Cover fully and thoroughly.
- Wait Till It Dries – this step accounts for a little patience. After aquarium safe silicone application has been completed from the inside and the outside, wait for a few minutes to let the sealants dry completely for a safe and firm seal.
- Start filling Water – after you’ve waiting for the aquarium safe silicone to dry, you may start filling in the fish tank with water slowly.
- Check for Leakage – once you’ve filled your fish tank with water, start checking if there’s still any leakage. If you’ve followed all the steps correctly, then you won’t find any issue whatsoever.
