And how much tank turnover would you need for your tank?It all depends on what you’re keeping in your tank.ĭifferent types of coral and even other types of fish have different in-tank flow needs. That means that the powerhead from our example moves the equivalent of 18.5 x 120 (volume of the tank) in an hour. So, 2250 divided by 120, will give us a turnover rate of 18.75. For example, let’s pick a powerhead that moves 2250 GPH, and use it in a 120 Gallons tank. Tank turnover rate is calculated by taking the powerhead’s maximum flow and dividing it by your total tank’s water volume. What is Tank turnover Rate and How to Calculate It? The best way to choose the right aquarium powerhead size is to use tank turnover rate formula. ![]() You can ramp it up or down, depending on the flow needs, and how your tank is maturing.Įven if you have a variable speed powerhead for your tank, you still need to size it correctly, according to your tank needs and capacity. Well, in such a case, all you can do is get rid of that AC powerhead idea, and simply go with a DC powerhead directly. This keeps you from having to buy multiple powerheads over the life of your tank because if you started with an AC powerhead at a specific flow level, and you add more coral later on, then you’ll need a higher flow level powerhead. One of the great things about DC powerheads is that you can buy one that’s more powerful than what you actually need, and after that simply adjust its speed to a lower level. To put this in other words, the AC powerheads run at a constant flow all the time – you plug them in, and they run at that speed constantly. Powerheads come in two types, there are AC powerheads, and there are DC powerheads.īesides the kind of power they run on, AC powerheads and DC powerheads’ critical difference is controllability. Those are simply meant to push water through a pipe, while a powerhead is intended to move water inside an aquarium. If you’re on the lookout for powerful filtration options, take a look at our best canister filters, or best HOB filters articles. On a side note, keep in mind that a powerhead is different from other types of pumps, like return pumps, for example. The simplest definition of a powerhead is that it’s a water pump that sits in your tank with the sole purpose of creating in-tank water flow. How to Create In-Tank Flow with Powerheads? Corals are going to need water flow to bring them nutrients, and while fish don’t need that much flow for these reasons, you can certainly agree with me here that fish are much more active when there’s plenty of in-tank flow.įor these reasons, let’s say if you want a still boring tank with fish that don’t move much, then you get a freshwater tank with some Angelfish. ![]() For both fish only and reef tanks, in-tank flow helps push waste into the overflows and into filters where it can be processed.Ī lot of waste sitting in your tank leads to nutrient issues, and we all know that’s not something you want floating around in your reef. What are Powerheads or Wavemakers? Powerheads and wavemakers for aquariums create an in-tank flow that’s important for several reasons. ![]()
