Order a package 1/2 to 1/3 the size of your tank. Their recommended size is way too much. Better to buy smaller and the population will grow to what's needed, rather than buy too much and have starvation die off to deal with. Especially when you already have algae to deal with.
Depending on what fish you have, and what they might eat, get hermits too. They also have bunch of other stuff like starfish. While you'r at it would add to your pod population too, with a bag of assorted live pods.
