Saltwater tanks are like video games, the tank keeps sending slightly tougher monsters as I progress. I finally, got cyano and it's giving me a run. As a new reefer, my 1st level monster was bubble algae, pulled tons of that out. Next was vermetids and the zebra snails brought them under control. I just re-introduced coral into my fowlr and that must have been the signal to send the new monster. My strategy is to just keeping changing water as it's only 14 gallons. A couple of questions: 1. What's generally out of whack when you get cyano? 2. I've got a doser, but never set it up. Should I? 3. Just wait it out or dump some chemical? 4. General advice Thanks.
