Yeah I wasn't bagging you for it or anything, many people make the same mistake. Just wanted to let you know, in the case that you get hooked and set another tank up in the future.
I personally don't keep track of drops per second, but I want it to take about an hour or two for my nano tanks. So maybe 45-60 minutes for every gallon of water changed. No idea how to convert that to drips though, that's up to you, or anyone who does measure that.
By the way, I just looked at your shrimp photo again and those are some beautiful shrimp! What I can see of the tank looks great!
