The problem is the intake slots clog quickly with plant debris.

When I do water changes, I simply pick the rock up, pull the filter out
the bottom, rinse it off in a bucket, and put it back. So far, I get very
little debris on it and what I do get easily rinses off.

OK, mine are made so there is no filter on the bottom but Roy reminded me
about some I have stored. As I recall they have an intake strainer I can
pull a sponge over to prevent clogging. My other powerheads not made the
same.

Or bits of plant debris get pulled through the intake slots and clog up
the impeller.

That is why I put the filter in the rock.

What filter? These powerheads have no filter?!?!?! They have slots where
the water is sucked in and a outflow tube.

I couldn't attach it to the
power head because of the way they were made. So, I used the rock to hold
the filter and power-head so that the power-head can only pull water
through the filter. The filter keeps the power-head from becoming clogged.

Are you talking about a sponge filter on it's intake screen? Not all of
these powerhead-like water pumps come with screens you can pull a sponge
over.

The two "rocks" that I have (they aren't actually true rocks) look like
someone pulled a post out of the ground that was concreted in. Then took
the concrete and cut it into 4 inch sections so that they have square
holes in the middle. I cut filters to fit into that hole and then have it
pull through the filter. In the end, about all the rocks do is give me a
stable place to hold the filter and power head where they are stable with
one another.

You have the type of powerhead that comes with a strainer then. I'm hoping
I have one or two out in storage.
