Saltwater Aquarium Air Pumps & Air Stones
The key to a thriving saltwater tank lies in mimicking the natural chemistry and flow of ocean water. Air pumps are key in creating circulation and instrumental in directing the flow of water into your filter and throughout your tank. Chewy carries an array of saltwater aquarium air pumps and air stones to help you promote circulation and oxygenation. Here are some of the most popular options:
- Circulation pumps: Submersible, fan-like pumps that create flow
- Wavemakers: Devices used to create and direct water flow, simulating natural ocean currents
- Air stones: Diaphragm pumps that push air through a porous stone to create bubbles
- Submersible pumps: Designed to circulate water or move it through tubing, as with a sump system
When choosing saltwater aquarium air pumps and air stones, the most important factors to consider are tank size and flow rate. The recommended flow rate for a saltwater aquarium is generally 20-40 times the tank's volume per hour, though certain corals may require much higher flow rates. Keep in mind that large pumps with high flow rates can be noisy, so consider a model designed for quiet operation.
Frequently Asked Questions about Saltwater Aquarium Air Pumps & Air Stones
Are air stones good for saltwater tanks?
While air stones may be good for improving gas exchange in saltwater tanks, they can contribute to salt creep and can negatively affect the aesthetics of your tank. Protein skimmers, wave makers, and other equipment that promotes surface agitation may be more effective in boosting oxygen levels.
How long do air stones last in a saltwater aquarium?
Air stones generally last for about six months in a saltwater aquarium, though numerous factors can reduce their lifespan. Some air stones are more susceptible to clogging than others, especially in a high-mineral environment like a saltwater tank. Cleaning your air stones regularly can help extend their longevity.
Can fish sleep with saltwater aquarium air pumps on?
Yes, fish can generally sleep with saltwater aquarium air pumps on. They're unlikely to be bothered by the sound of the pump, but if it creates too much flow or surface agitation, it could disrupt their swimming and resting habits.
Can you over-oxygenate a saltwater fish tank?
Though uncommon, it is possible to over-oxygenate a saltwater fish tank. Natural factors such as warm temperatures, exposure to sunlight, and overabundance of algae can contribute to high oxygen levels, but the biggest risk for over-oxygenation is adding pure oxygen directly to the tank.
How often should you replace the air pumps in a saltwater aquarium?
You should replace the air pumps in a saltwater aquarium when they stop working properly or start showing signs of wear and tear. With proper maintenance, air pumps generally last for 2-3 years. If your pumps start making unusual noises or fail to operate consistently, it may be time to replace them.
