AquaClear 10 Powerhead Aquarium Water Pump- 80 GPH specifications:
Hydor, a well-known name in the Aquarium Supplies industry today, brings to you a broad spectrum of an effective Hydor Power Head model.
The convenient suction cups and attachment brackets with an adjustable clamp allow the Aqua Clear Powerhead to be mounted in most aquariums with either rim or glass mounts.
The Aqua Clear 70 Powerhead has an option for reverse flow operation. In the reverse flow setting, the water is drawn directly from the aquarium by the Powerhead and forced down the riser stem and below the undergravel filter plate. (In conventional operation the water is pulled through the gravel and plate and up the riser stem.) The water then passes upward through the gravel layer-feeding and oxygenating vital bacteria colonies from below. The biological filter develops from the bottom up. This reverse flow helps to keep the substrate cleaner by keeping dirt and debris near the top layer so that it can be easily removed. Since the water is forced evenly through an unobstructed bottom place, there is much less possibility of "dead spots" to go anaerobic.
dependable power head aquarium pump at a GREAT price!

Finding the right powerhead for your tank can be the difference between happy coral with clean sand beds and sandstorms/detritus build up. Additionally we want a powerhead to match our specific needs. New aquarists aren't looking for wallet destroyers like the Vortech, while those who are building large tanks will need something they can depend on for years or even decades. Taking these various factors into account I've gathered up what I consider to be the best aquarium powerheads of 2016. Before installing the Hydor Koralia Evolution you will want to reinforce the interior pin. It is the main cause of failure in the model. Simply make a small layer of aquarium safe adhesive around the pin and it's good to go.
The Koralia attaches just like the Tunze, minus the four rubber mounts. Additionally the magnet has a suction cup underneath it. This gives a bit more holding strength, which helps a low when using as a back up powerhead to large tanks with thick glass. This does not mean the magnets are weak and you still should never bring them near one another.
The cord is 6 feet long which gives you a good amount for free positioning while still creating a drip loop.
Note: The Koralia Evolution can start running in reverse, which is fixed when the propeller spins forward and strikes the flow checking pin. If you do not reinforce this pin the powerhead will often break it. If this happens your powerhead will run in reverse 50% of the time when started. I would be lying if I said I wasn't a Tunze fan, but these pumps easily earn their place as the best aquarium powerhead. They are powerful, reliable, nearly silent and fairly small. The price is a bit up there, but it is money well spent as the powerhead still runs like new over a decade later. Over the past few posts, I’ve broken down some of the biggest electricity costs associated with my saltwater aquarium. Your and (if you have one) probably consume the most electricity (and therefore create the biggest cost). Next on the list are the aquarium powerhead costs. Some aquarists choose to alternate the flow from their pumps to simulate wave, surge or turbulent flow–but in my tank, I run my powerheads 24 hours a day, 7 days a week–and there are two of them.
