Hey guys. I'm looking to add a Powerhead to my 75 gallon tank for my Denison barbs and Rainbowfish to swim in. Theyre getting bigger and seem a bit bored sometimes without a current. Ive also read it can aid in plant growth and filtration. I don't want one that's going to blow so hard they don't like it.
It all depends on what filter you are using HOB or Canister and the direction of the outtake if using a canister. In addition, is your 75 gallon planted?
I hopes this helps! Thanks for the reply! I am running a Aquatop cf uv canister and a marineland b hob. About g worth of filtration. Yes, it is planted with a good amount of jungle val. Heres a pic for reference. Bump: Any other opinions? Click to expand Thank you! Would this be the GPH one? I was debating between the or honestly. Edit: I re-read and realize that yes its the Do you think the would be too much? You cannot have too much flow. I have GPH in my 8g tank about x turnover and don't have any problems keeping lower flow corals.
There are still going to be places with less flow, even in high flow tanks. I've got three Koralia magnum 5's gph for my 72x20x21 Should I pick up one more? If I'm going to eventually put them on a wave maker does that change how many you need? Originally Posted by sniper2be.

Another thing to know when choosing the GPH rating of the aquarium powerhead is flow rate distribution between multiple units. If your fish tank requires a total of GPH, then it would be smart to actually buy 2 separate powerheads rated at GPH each.
I have a separate section below specifically discussing powerhead placement, which will make things clear when you reach it. By the way, a powerhead that pumps high-pressure jets of water is not necessarily powerful in that the high-pressure jets could not be worth many gallons per hour. While any other powerhead can perform its water circulation duty, how each model is designed determines how efficient it can be. The strainer covers the intake route to keep your small tank pets from being sucked into the hole.
There are aquarium powerheads fitted with switches to adjust the water flow rate and speed. Still, more advanced ones are wireless and have remote control pads. With these, you can select different modes depending on what you aim to achieve at any given moment. Excess heat in your tank could raise the temperature, which in turn could affect the well-being of the most heat-sensitive of your reef aquarium inhabitants. So this is what you should also watch out for in a powerhead concerning heat emission:.
This can be uncomfortable for your reef aquarium fish and corals. Some marine fish are so sensitive that a slight increase in temperature is enough to alter their movements or slow them down.
On the other hand, note that a unit whose strainer holes are small can easily clog. The clog slows the water intake, forcing the device to overwork. This leads to overheating too, so choose a powerhead with a large-hole strainer if the size of your aquarium fish allows it. How long is your powerhead going to last? Here is what to check out in terms of quality and durability:. It generates heat and pressure and is submerged most of the time.
It should be sturdy enough to withstand its own vibration and the waves from other devices like the filter. You do not want stray electrical voltage to one day leak into the aquarium water and electro-shock your fish or even you, so the overall quality of the powerhead is crucial.
Energy consumption is another factor you should not ignore. Here is what to consider when it comes to energy efficiency:. In my recommendations below, I made sure to only list top models, which usually include lower electricity consumption. Here is what to consider when it comes to ease of installation and maintenance of an aquarium powerhead:.
You should choose a powerhead that you can easily install by following the manual. The manual should be clear enough, with no ambiguities.
Again, taking it apart and assembling it should also be simple so that you can clean it and take it back whenever you do regular maintenance. Talking of routine maintenance, for a powerhead, this should be once every two months to avoid clogging. Powerheads are generally low-noise devices. The noise they make is insignificant, considering they are mostly submerged.
I speak from personal experience, by the way. When you have your fish tank in the sitting room, the sound could be bothersome if you end up with a noisy device. Doing maintenance is also essential; without maintenance or cleaning, solid wastes soon clog the intake line, causing the device to make a choking sound.
With all that said, I am going to review some units, so that you can choose the best one and be sure that your aquarium powerhead of choice satisfies the flow requirements of your corals. I will only mention products that I like and I have used, or some reliable fellow aquarist I know has used and recommended to me.
One good thing I have to put in from the onset, with no strings attached, for the Hydor company is that should you at some point order a replacement part, they ship it to you for free. These units are arguably the best when it comes to providing flow in a nano aquarium as the smaller Hydor Koralia powerheads are specially designed for just that. For positioning, they come with a magnet that you place on the outside of the fish tank to hold the suction cup securely in place.
The cords come with a protector just in case you have the kind of fish tank inhabitants that like to chew on whatever is in sight. Anyway, I give this new Koralia version thumbs up as far as energy consumption is concerned.
It has been improved to be efficiently providing a very reasonable ratio of cents for electricity per GPH. With all said, this is one of the best nano powerheads I can confidently recommend for a small saltwater aquarium. Check my recommendation section to see which exact model will fit the gallon capacity of your reef tank.
If used correctly, this compact powerhead moves aquarium water around perfectly, giving no room for stagnant spots. Anyway, with the Hydor Koralia Evolution we are looking at a circulation pump that is powerful, can be set on a timer, and is rather durable in the long run. On top of that, the product is rather cheap by the reef keeping standards of sometimes overpriced equipment, which I highly appreciated when I initially tested this in my reef tank. This powerhead also came in handy when I added salt into my saltwater fish tank which should usually be thoroughly and quickly mixed.
I guess this makes the Hydor Koralia Evolution one of the best powerheads for a saltwater reef aquarium. Aside from the good overall GPH potential, I like this unit most when it comes to energy consumption as it takes in only about 5 watts.
The suction cup and the exterior magnet also ensure the powerhead itself never falls due to its own vibrations. A drawback worth pointing out is that these powerheads have no flow control switch, but you can always change the flow direction. However, for the affordable price in combination with the strong GPH capability, I think this is a fair trade.
