    Default Powerheads and Flowrates

    0 Not allowed!
    Just a few thoughts on powerheads to consider when contemplating one for your tank.

    Powerheads are rated by flowrate which is really a poor rating system for powerheads as it doesn't really tell you the whole picture. There is a difference in kinds of flow. The big issue comes when you deal with pressure and volume. Some powerheads are high pressure but low volume, while others are high volume and low pressure. So, what does this mean? Well, the high volume powerheads still move lots of water, but they do so in a much gentler manner. Powerheads that fall into this category would be the Koralia line from Hydor, and the Tunze Stream/Nano Stream lines. These powerheads use a propeller for moving the water in a broad column. These powerheads also have the nice feature of being safe for your fish as they do not have a single small intake that is also high pressure. The mounts on these powerheads are another great advantage; both brands use a combination of a single large suction cup and a magnet.

    Powerheads such as Maxi Jet, Penguin, and Aquaclear are all low volume but high pressure. These powerheads use a small intake with a single narrow output. This creates a harsher current for your fish, corals, or plants. These powerheads are well suited to use with a under gravel filter or for a CO2 reactor. While these powerheads can be used in reef tanks or regular tanks, they are as well suited for that application as a the Koralia or Tunze powerheads. The Maxi Jet powerheads can be converted to a low pressure/high volume setup with the use of a Sureflo Mod kit. The biggest draw back to most of these powerheads is their mounts. Most of them are mounted with the use of suction cups, and these frequently let go and are the cause of many a sand storm in reef tanks.

    So, it boils down to this: what is your application? If water movement is the goal, then go with a Koralia, or a Tunze, but if the goal is filtration or CO2 injection, then one of the others would be well suited to your needs.

    Great comparison, very informative
    As I get older I find myself thinking about the hereafter - I go into a room and then wonder what I'm here after.
