I agree. Best stuff ever.

I have oly two words to contribute to this discussion: Hamburg Mattenfilter.

whether its lava rock, bio-balls or rings, I put any of that type media in bags, to make it easier to pull out the bags out of my sumps, and give a quick rinse off.
I give those bags of media a quick swish in water change water during almost every water change,
And according to my ammonia testing, those quick rinses have not hindered any biological ammonia consumption.
