What to Consider when Buying Overflow Fishtank Products

In your fish tank, the overflow box is a special chamber where the water runs over the top and drains out of a pipe at the bottom. The overflow box is underneath the fish tank. It keeps the water in your aquarium level as well as improves gas exchange, increasing the amount of oxygen and reducing carbon dioxide. Opt for healthier water in your aquarium fish tank by installing an overflow system, but first learn about the considerations for purchasing one.


Drilled and Hang-On Overflows

The first thing to consider is the type of the aquarium overflow to purchase. Ideally, your fish tank has a pre-drilled hole inside the tank for attaching the overflow mechanism that moves the water to the lower tank. The drilled overflow is quite simple in design and allows water to spill over once the water level reaches a few inches below the tank's rim. This type of overflow may fail only in cases where the drill hole clogs and prevents drainage. The drilled overflow takes up some space in the tank and slightly reduces the amount of usable area inside. You could also choose a hang-on overflow that you attach on the back of the tank that extends over into the aquarium. This type can handle less water than drilled overflows and is less reliable, but is a great option if you do not have the necessary hole for the drilled overflow.


Sump Noise Levels

The sump tank is a chamber into which the water drains before returning to the tank. When the water enters the fish tank sump, it can get rather noisy. If you keep your aquarium close to your bedroom, you may need to look for ways to reduce the noise. You can do so by installing a special valve. In addition, you can find a quiet overflow system if the noise bothers you.


Simple Plumbing

There are no limits to the aquarium and overflow system design. However, it is best to keep the plumbing as simple as possible because too many sharp bends in pipes may result in reduced flow rates and other problems. The simpler pipe designs do not necessarily reduce the overall noise, but you can solve this problem with other methods, such as by drilling a hole in the pipe and installing a valve.
