Cleaning bioballs?

[dewilde2]

I just purchased some used equipment from someone on craigslist, and it came with a HUGE box of bioballs that appear to be in excellent condition- two sizes. They had been sitting in a garage for a while, so I did rinse them off and sort them out. Is there anything else I should do to clean them before using them in my own tank?
Thanks!

I'd probably just blast them with a hose and give them a good hard rinsing with clean fresh water.

If there is a large size difference between the batches, you might check how they fit in the filter. I would not be suprised to find that a layer of 2 of the larger balls fails to fill a basket but that adding the second size to the mix fills it up. That is why I would have more than one size.
