I looked at scoops like that but I realized that because I use powders in mine (nutribalancer mineral mix and fish meal) I prefer not to have such large gaps in mine. If I didn't mix the powders in and just added them later when feeding (like rr does) that would work okay for me.
Nice looking scoop!
There's fish meal in mine too, but almost all of it gets stuck in the blob of grains in the scoop and doesn't drain out with the liquid. So I guess the mound of grains acts as a sieve to keep the fish meal powder from escaping with the liquid. I don't know, but it seems to work pretty well.
