Once the front viewing panel was scraped clean of film algae, the corals looked a lot better. While my arm was wet, I tried out some Aiptasia Rx today to see how well it would work. Too bad the peppermint shrimp in the tank don't do what I hired them to do. Maybe they'll get motivated?Water parameters are doing quite well these days in this tank. I seem to have the dosers dialed into a good spot.
