cool ,,glad to see they are getting used up. I think 80% of them were brand new. they came in the sump when i got my 200 off craigslist about 65 gallons of them !! this guy who had my tank ran a fowler with it and had the sump packed with them .

I replaced the lava rock in my pond filters with the bioballs, and I'm getting more flow through the waterfalls now. These are the submerged Tetra filters so with the weight out, I set a large tufa rock on top of each one in case they become bouyant. Thanks again.
