Anyone have 5 gallons of bio balls for grabs?

There's cheap options that offer greater surface area than bio balls, like plastic scrubbing pads. Not that bio balls don't work.

Go to a hydroponic store and buy the clay balls. Big bag full for about 10.00. I got a third of a garbage bag for 10.00. Work great. Very porous

I have a bucket of plastic bioballs if you are interested for $10
