i recently had my first nitrogen spike which i followed up with a 25% water change (all other parameters were ok). i feel like i don't have enough algea yet and am possibly over feeding my fish. i have four damsels which i feed two pellets each, twice a day. i feed my two emerald crabs one pellet each once a day. i don't feed my starfish as i was told there's no need to. any suggestions? thanks in advance
