What is the main purpose of a "power head" in an aquarium?

Question

I have a 29 Gal aquarium with an under grave filter as well as a power filter...do I need a power head? If so, Why?

Thank you reptile guy...You were a great help! I do have fantail goldfish...guess that tell me I need one. THANKS AGAIN!

Answer 1

A power heads purpose in an aquarium is to increase the efficiency of your under gravel filter. It does this by increasing the flow of water through your gravel bed, making it more oxygen rich for your good bacteria in there. If you need it, depends on how heavy of a fish load you have on your aquarium. If you have goldfish, I would say yes, they tend to be dirty fish and create a lot of waste and the more biological filtration you have the better! Hope that helps.

Powerhead Aquarium

Answer 3

It would replace the air pump and stones on the undergravel filter and sit on top of the lift tube. It will increase the flow of water through the undergravel filter and increase it's efficiency. A power head is not a bad idea with undergravel filters just because it turns them into a very effective biological filter and on a 29 gallon tank the extra lift it will provide over just an air pump would be nice since the 29 is so deep.

Answer 5

The purpose of a power head is to creat movement of water. Movement is the only way Dissolved oxygen can get into the tank. IF used on an undergravel filter, it is designed to pull debris to the bottom of the tank while spuing cleaner water out of the top. It isn't designed to take the place of air pumps since they are for decoration only anyway.

i think a similar way yet giving up desire will no longer replace something, in fact it will make it worse. maybe spectacular now that is no longer a while to discover a job which you like.i think of you're looking too perplexing, each so often in existence you're able to permit issues come to you, which era is acceptable for. i've got faith you will discover the ideal job it rather is satisfying and pays solid money, you basically could have a impressive concepts and attitude to this difficulty. there are various websites that furnish advice on the thank you to positioned up a e book and no person ever stated it became impossible to sell tens of millions of copies of their books. think of outdoors the container, do some thing, do no longer basically say you prefer to positioned up a e book. flow slowly out of your convenience zone, make some telephone calls, do a splash study and you will have a beginning factor. understanding what you prefer to do is an extraordinarily solid beginning factor and should assist you be triumphant. solid luck and that i desire I helped.

Answer 7

Yes power heads were used to run underground filters, which hopefully nobody uses anymore, they suck.
But you can and should use a power head for general surface areation. You can position them to create water flow for filter efficiency as well.

Answer 8

Though not an absolute requirement in your tank, powerhead (which are just little mini-pumps for moving water around) can add overall benefit. They not only stimulate circulation and prevent dead zones in the tank, they also create flow patterns in the water that simulate natural waves.

Some people put their powerheads on "wavemakers", which turn different ones on and off in a regular pattern, further creating wave effects.

Answer 9

circulate water for filtration and aeration and in some cases heating the water

Answer 10

i hate underground filters! they trap poop and other stuff under neath the gravel. u can use them but i don't like them, underground filters are just for circulation.
