How to Set Up a Sump for Your Saltwater Aquarium?
Setting up a sump for a saltwater aquarium involves selecting the right sump size, installing baffles and chambers, and setting up return pumps and plumbing.
Choosing the Right Sump Size
It’s crucial to choose a sump size that fits your existing aquarium and meets your filtration needs. Generally, your sump should be about 25% to 40% of the size of your main tank.
A 75-gallon tank would benefit from a sump between 18 to 30 gallons. This provides enough space to include all necessary filtration equipment. Always make sure the sump can handle the backflow when the return pump is off.
When in doubt, opting for a slightly larger sump is usually better because it gives you more room for additional equipment like protein skimmers and reactors.
Installing Baffles and Chambers
Baffles and chambers help to separate different areas of your sump for specific purposes. Place the baffles to create at least three main compartments: one for the protein skimmer, another for refugium, and one for the return pump.
Install the first baffle after the protein skimmer compartment to prevent bubbles from reaching the return pump. Ensure the refugium chamber is large enough for macroalgae and live rock.
An adjustable baffle can be useful for regulating water levels, which is particularly important for maintaining optimal skimmer performance. Glue the baffles securely to avoid leaks and shifts.
Setting Up Return Pumps and Plumbing
The return pump is key in circulating water from the sump back to the main aquarium. Choose a pump with the right flow rate for your tank size; it should be able to circulate the water volume 3-5 times per hour.
For example, a 75-gallon tank needs a pump rated at 225-375 gallons per hour (GPH). Ensure the plumbing is secure to avoid leaks.
Use flexible tubing or PVC pipes to connect the pump to the tank. Adding a valve helps to control the flow rate, ensuring smooth operation. Remember to frequently check for blockages and maintain the pump regularly.
What Are the Maintenance Requirements for a Sump?
Maintaining a sump for your saltwater aquarium isn’t complicated, but it does require regular attention. First, you’ll need to clean the sump periodically.
