Powerheads are certainly one of the most popular ways aquarists create water flow in the aquarium, yet the technology has its flaws and may not be appropriate for advanced marine systems.

Powerhead: A power head is a small, submersible pump which is used to power wavemakers and UGF's (undergravel filters).
Powerhead: A small submersible pump commonly used inside an aquarium to provide additional water movement. Several powerheads can be used in conjunction with a controller unit to simulate natural wave actions.
Powerheads are pumps that are generally submersed within the water. Powerheads use a simple design, their core and windings are encased within an epoxy filled cavity thus eliminating electrical current leakage into the water.
Powerheads provide a superior method of driving undergravel filters, helping to improve biological filtration efficiency through optimal flow rates and greater oxygen levels.
Powerheads used to be used as part of under-gravel filtration systems, however they are mainly utilized for moving water around, as modern reef aquariums need lots of flow around the tank to satisfy the needs of the corals.

Q ...
A powerhead sat on top of a canister of sponge media. The powerhead draws water through the media via vents in the canister.
Powerhead and canister filter:
Principle: These tools are used to pump water through the aquarium and through various filter materials. A wide range of capacity and power makes them suitable for almost every tank.
Cons: Powerhead provided could toss around even the largest Oscar and is of no use due to its high flow rate.

Air or powerhead driven sponge filters have similar upkeep requirements, but may call for greater care in rinsing if they are used for biofiltration as well as mechanical filtration only.
Get a powerhead rated at about 600lph for circulation
- this is fine just for slow-movers like "Nemo" (Ocellaris clown), and corals that don't like high water flow,
like most LPS hard corals, e.g., anchors, hammers, elegance, etc.
Filter/pump/powerhead Cleaning
Over time your filters and pumps and powerheads will accumulate a mass of gunk. It is good to clean this gunk out every 3-4 weeks. Just take out all the parts and rinse them with water. DO NOT use any chemicals! ...
2x Seio 1500 Powerheads - $160.00
Intense circulation is important, but you do not want a concentrated blast of water aimed at your corals. The Seio and Tunze equipment give you a soft but large volume of water movement.
Buy a thermostatic heater, thermometer, and either a good air pump with airline tubing, or a powerhead that pumps at least 3 times as much water per hour as the size of the aquarium.
Air bubbles or powerheads are used to pull water down through the gravel and up through the lift tubes.
powerhead A small submersible pump. They have only one moving part, called the impeller. They are useful to create current within a tank or to drive filters such as under gravel filters, canisters and protein skimmers.
Four powerheads circulating water in the tank for a total flow of over 1000 gallons per hour (the tank was 8 feet long and it was estimated that although this gave a considerable amount of flow, in hindsight more flow would have been better still.
Powerheads
A powerhead is a water pump that runs completely submerged in a tank. They typically attach to the ``lift tubes'' associated with UGF filters, pulling water through the lift tube.
Add a heater to get the water to the appropriate temperature (78 - 80o F) and a powerhead to circulate and oxygenate the water.
Now you will need to pre-clean the rock. This will speed up the curing process.
This includes powerheads, filters (both internal and external), protein skimmers, circulation pumps etc.
- Do use a timer if possible on your tanks lights as the inhabitants like regularity with respect to their daytime and night-time.
Once a group of juveniles has been acquired, and settled into a new home, the aquarist may notice that they begin swimming up and down the aquarium glass in groups, alternating this with 'powerhead surfing', ...
In each corner of the aquarium there is a clear pipe attached to the under gravel filter plate, usually with an air stone inside the tube or a powerhead on the top. As the water is being drawn up the pipe water is being drawn through the gravel bed.
We can reproduce these conditions on a much smaller scale by using either a wavemaker (which can be quite expensive and hard on power heads) or by using multiple powerheads placed strategically around the tank to generate these turbulent water flows ...
Set the powerhead, along with the heater, in the bottom of container. Plug them both in. Take note of the tank temperature on the floating thermometer, then place the thermometer in the mixing container.
Powerheads will provide the best method for current. It is best to keep this Knifefish by itself in a large aquarium. Tankmates, if any, must be very large and capable of defending themselves without being aggressive enough to attack the Knifefish.
A powerhead is utilized to draw water from a sponge based filter that is positioned at the other end of the tank (again oblong tanks are required).
The addition of a powerhead or the use of a slightly oversized filter will increase filtration and water movement to help recreate natural conditions.
Water circulation is accomplished through the use of three submersible powerheads (flowrated at approx. 200 gallons/hour) plus the main sump return (approx. 300 gallons/hour). Water movement is very strong and turbulent.
A partial solution to this dilemma is to run the powerhead in reverse, sending water up through the gravel.
Description: The zipper loach does well with water that has a current, so the use of a powerhead is reccomended. A sandy or small gravel substrate is preferred because this species digs constantly.
The desired turbulence can be achieved by strategically directing several powerheads and return hoses so their flows deflect off of each other or bank off the aquarium glass.
022 and stop there, wait another few days with a powerhead circulating the water, the ph will be quite high when the salt is first mixed, and it also can give a false reading for ammonia when just mixed as well so don't be alarmed if you notice this.
To induce the spawn you simulate the rainy season by creating a strong current with powerheads or similar, turning the heater off and doing daily water changes with cooler soft water (e.g. rainwater or R/O water) of about 20%.
This can be done with computer controlled powerheads. Some freshwater fish and many corals dont like being blasted by powerheads and there are powerheads that diffuse the water gently rather than in a straight jet of water.
Another important thing to remember is that since they do come from a fast moving river environment, they need a tank with lots of clear, well filtered and fast moving water which can be achieved with proper filtration and the use of powerheads.
Breeding:Allen bred these fish by doing a 75% waterchange which also dropped the temperature 5 degrees Celsius, with part rainwater in combination with a powerhead added to the tank.
Water movement should be kept to a minimum, which means that power filters and powerheads are not suitable. Bettas may be kept in a community tank as long as the water conditions are met, and if no aggressive or fin-nipping fish are present.
Wave Maker: A device which switches powerheads on and off at timed or random intervals, in order to simulate wave action in an aquarium.

Refers to the injection and distribution of air into your tank, either by gas exchange at the water's surface, an air pump or powerhead with venturi jet. The purpose of aeration is to supply water with enough dissolved oxygen to sustain life.
It is also reported(Baensch and Riehl, 1996) that it inhabits the fast flowing parts of the river. However, if a powerhead filter is applied to a tank you will see the fish migrate to the slower flowing parts of the tank, ...
Without a trickle filter (wet/dry and trickle being one in the same) the only place you have this interaction between carbon dioxide and oxygen is at the surface where there is water agitation via powerheads, powerfilters, ...
You unplug all the equipment and examine them one by one. Is any electrical part of the powerhead filter submerged in the water? Are the wires in the overhead reflector lamp properly insulated? They're all clean.
Our readers have found ways around this by adding de-chlorinators, like Seachem Prime, directly to their tanks before adding the tap water or by using powerheads to pump stored, purified water into their tanks.
