Freshwater shrimp can be fun to keep and there are dozens of species and varieties available. They stay small, eat algae, and some don’t even need a heater!

Carbon is a chemical filter media for aquariums which removes dyes, odours and impurities from the water. But how long does it last?

Bubble algae is a bottle green single-celled algae which forms jelly bean or round, marble-like shapes in the marine aquarium.
