Choosing The Right Tank
Setting up a fish tank with LED lights starts with picking the right tank. The tank size, shape, and material affect your fish and plants.
Location and placement also matter for the tank’s health and how it looks in your room.
Tank Size And Shape
Choose a tank size that fits your space and the fish you want. Bigger tanks hold more water and are easier to keep stable.
