I currently have a 35 cube running for 2 months. I am wondering if a skimmer is neede/suggested for my setup. I have a tidal 110 HOB. I have a 6 line wrasse, cleaner shrimp, 15 ble legged hermits, pistol shrimp, maroon gold stripe clown, and 2 emerald crabs. Just started coral with a frag of zoas. I'm looking to add more soon but am wondering if a skimmer would benefit the setup. I am also dosing with the reef pro a and b for alk and calcium as they were a little low. Any info/ tips would be appreciated.
