David, Its generally best to thoroghly rince your media before putting it into your growbed. If you've already contaminated your main fish tanks, then you might be ok if you run your system for a while--but you may find a water change in order. Btw Coir is coconut fibre. As for hydroton floating, it will generally float 24-48 hours. I rince mine, soak it and then drain it and add to the media bed. If you're just starting, you have plenty of time. If you're fishless cycling, the ammonia may well clean up your water for you, if not, then a water change is your best bet. Any bacteria you've grown should be fine through the water change.
