will be interesting. @ German rivers sometimes I can't filter more than 150ml by 0.45um so I am always thinking about prefilteration and the best combination.

Interesting work, did u test successive filtration or prefilteration? 64um followed by 0.45um?

So here we tested whether increasing volume of water processed, indeed improved species diversity detection metabarcoding. We compared two extremes of volume-pore size combinations 1) 1L via 0.45 um filter and 2) 3500-7000 L filtered via 64 um tow net. (3/8)

I usually use Forensics too, it makes it easier to transfer the meaning for no scientist
