I got my lava rock at Lowes in the outside area where they sell all the paving stones and wall rock. Just make sure you rinse it WELL before using it in your filter. You may get some red stain at first but it goes away with time.

Thanks for the information cherokee_joeshoeboot.
I did a google search on lowes website and came up with two products which might be what you described:
One is ProCom Decorative Lava Rock and the other is American Countryside .5 cu ft Lava Rock (label says "RED Lava Rock".
Which one would I use in my filter?

Thanks gain for the reply..

My store only carried the red and that's what I got. That's why I mentioned rinsing it well before flowing water through it to the pond. It will give off a little red color for awhile. not sure if it's dye or why it's red.

We switched from lava rock to bio balls because of the weight, it gets heavy by the time you need to clean it. Just a different viewpoint.
