When I prune stem plants, the foreground etc, inevitably there ends up being a ton of tiny plant clippings, leaves
etc floating around the tank. Its a royal pain to fish it all out with a net. So, here's a solution.
Cut the bottom off the bottle and stuff the filter foam into it.
Attach the bottle to the powerhead's INTAKE.
Invert it and stick it inside your tank - just slightly below the surface.
It sucks all the debris into itself, the foam traps it, clean water exits the powerhead. In a few minutes,
your water is pristine again. The heck with that net!
I just pruned my hairgrass foreground in my 215G tank. Stuck this fella on there for 10 minutes
and it cleaned up the mess for me. Sweeeeeeeeeeeeeeeeeeeeeet!
BTW - not my idea - saw it in an old Aquajournal picture in the background.
