When you are looking to install an overflow in your aquarium, you’ll notice that most of them include a standpipe. The standpipe, also known as the drainpipe, is a vertical pipe that is positioned to drain water out of your tank. You can install an elevated standpipe if you’d like to create a quiet overflow. The best part about this system is that you don’t have to worry about the sound of running water in your aquarium – you can simply install it yourself!

When you’re installing a standpipe, you’ll need to consider the type of system you want. A siphon standpipe has a valve in the center that opens and closes once the water level rises to a certain level. This type of overflow is virtually silent, and it’s also good for smaller aquariums with sump systems. Another type of standpipe is an open channel style that lets air into the tank through an airline.

Rubber vibration mats

Aquaria overflow systems are notorious for their noise. Many aquascapers, car owners, and computer technicians have tried to make their overflow systems quieter. The best way to do so is to invest in rubber vibration mats and insulating material from specialized stores. If your aquarium’s overflow is noisy, you can also try installing a noise-absorbing material on top of it. In this way, you can avoid the sound and vibration of the overflow system.

Rubber vibration mats can be purchased from car audio vendors or washing machine dampeners. Thin rubber mats can be positioned between the sump and the aquarium stand to reduce vibrational noise. For aquariums with hard pvc plumbing, a small section of silicone or vinyl hose can be added between the return pump and the hard pvc pipe. This can cut the vibration from the return pump as well. However, this will only help if the overflow pump is a high-end model.

CPR overflow box

For those who have been keeping aquariums for years, you may have heard of CPR. This small private company made some great products, including the first hang-on protein skimmer. The Bakpak is one of their most popular products, and this overflow box is no exception. It features several fail-safe options, such as an aqua lifter pump, which will keep the water level in the tank consistent and noise-free.

The most robust and silent overflow box is the CPR CS100. It’s a sturdy, durable product, but there are other products available on the market. If you’re going for a drilled aquarium setup, we recommend the Eshopps Eclipse or the Fiji Cube. You may also want to consider a CPR overflow box, if you have bean animals. While external overflow boxes have a small footprint inside the aquarium, you’ll need to drill the tank to install them. A hang-on option, like the CPR Overflow Box, can be a more inexpensive solution.

Eclipse overflow box

An overflow box allows water to pass through your tank’s walls and into your sump or filtration system while reducing noise. The Eclipse overflow box is a DIY project that features an integrated overflow system and slim, black design. The Eclipse overflow box is an easy plug-and-play upgrade to any tank. This device can transform a standard glass tank into a reef aquarium and is ideal for any size aquarium.

The Eclipse overflow box is designed to sit on the back wall of your tank, which is why it has a small footprint. The box includes all the necessary tools for installation, including a hole saw and a drill template. Once installed, simply align the template on the wall of your aquarium. After that, you’re all set. You’ll be able to enjoy your aquarium’s quietness without sacrificing your view.
