1. Make sure that the bottom of your aquarium is fully supported by your aquarium stand. If you have any gaps in the structural integrity of your aquarium, it is much more prone to breaks and leaks.
2. You should never used any alcohol to clean the inside of your aquarium. Alcohol can pose health problems for the fish in your aquarium.
3. In larger aquariums, you should put a few scavenger fish in the tank. Scavenger fish will help to clean up left behind food and wastes from the other fish in the aquarium. This is a good eco friendly way to keep your aquarium clean.
