And I thought "OMG YES I am not alone!" I have the same problem. I haaaate those little balls. I think I get rid of some during tank maintenance time, and the next day I swear the damn things reproduce.The only problem I have with Osmocote+ is those little yellow balls that contain the ferts will eventually end up all over the top of your substrate.
