One unit like the new Jebao SLP-10 wavemaker is more than suitable in this case. If you have a 30-gallon tank and aim for a 20X turnover rate, you will only need a wavemaker rated for 600GPH. Multiple smaller units are better than one larger one.Ī smaller tank will usually only require one wavemaker. This will allow you to position them in different locations and get better water movement eliminating dead spots in your tank. You can have both wavemakers that are rated for 1000+ GPH each. In our example above, a 100-gallon tank that is 5 or 6 feet long will need 2 wavemakers placed on each side of the tank that equals your desired turnover rate. Larger tanks will likely require multiple wavemakers where smaller tanks may only need one. The size of the aquarium will also play a role in determining the size of the wavemaker. If you are keeping SPS corals, you may need to increase this number. For example, if you have a 100-gallon reef aquarium with LPS corals, aim to have your water turnover at least 2000-3000GPH. A general rule of thumb to aim for is a 20-30x turnover rate for the water volume in your tank. This is basically a number given to the number of times your main water volume will be cycled or turned over in your tank. You will often hear the term turnover rate being used when determining water flow in your tank. For example, a Copperband Butterflyfish prefers to have low water movement whereas Clown Tangs prefer high water movement. What do you plan to have in your tank for livestock? Certain corals like softies will only require low flow, LPS corals prefer low-medium flow, and SPS corals will do better with high water flow rates.Ĭertain fish also prefer different flow rates. Well, that will depend on a few different factors. But there are a few more things you will need to consider: How much water flow do you need? Use this as a guide and take it into consideration.
The manufacturer of the wavemaker will give a maximum tank size rating and flow rates. The porous surface of live rock will contain millions of bacteria that will break down ammonia, nitrite, and nitrate keeping it cycled. It holds most of the beneficial bacteria that your tank needs. Liverock is going to play a huge role in the overall health of your tank. Water flow will also remove and clean waste from within and around the corals. They also depend on it for bringing them food like phytoplankton and zooplankton to catch with their polyps. Corals will appreciate water flow to keep their tissues healthy allowing them to grow and maintain vibrant colors. Water flow promotes gas exchange, which increases oxygen and decreases carbon dioxide. Without it, your corals will not survive. Fish, coral, rock, and other livestock depend on it and there are several benefits to having proper water movement in your reef tank. In this comprehensive guide I will cover:Ĭreating enough current and water movement is crucial to maintaining the health of your saltwater aquarium.
