Always pre-treat with low PH before use.
Best to wash it well first.
There's an amazing amount of pump-clogging red dust after it rattles around in shipping.
Then soak for a day in PH 5.0 water.
Then test that water to see if you need to do it again.

After that, the only hassle is spilling the li'l buggers.
They get everywhere and are no fun with bare feet.
