I have & I was pleased with the Amphipod population that I received from them.Ok I just seeded my tank with 2000 pods from reefs2go anyone ever use these?
I couldn't tell how many Copepods there were because they are just too teeny-tiny to see. You need to get a strong magnifing lens & have fun looking for them on the glass. I use the lens from a torn up gun scope & it works great.
I was startled a few times at seeing an Amphipod through it. If they were as big & wicked as they look under magnification, I'd fear putting my hands in the tank. Good Luck with your BUGS!!
