Brevity snips

The biggest problem I had was fooling with them to get the situated to
get the flow pattern that I wanted.
=======================
Mine will stay in place.

It wasn't so much getting them to stay still that I had the problem
with. With it "locked" into the rock, I couldn't lean it to get a more
upward flow that I wanted and the directional attachment didn't quite
give me the direction I wanted.

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.

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. 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.

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.
