Powerhead

[canadawest]

Hey Ben,

Most powerheads come with little guards that attach to the intakes to help prevent these little accidents.

For example, I use Maxijet powerheads, and they all have the little intake guards that they come with on them.

If yours dont have little guards, they should at least have a sponge prefilter to prevent this, but you have to clean the sponge filters once a week or so to help prevent waste buildup which will increase your nitrates.
