i have three turbos and they have been great, they mow down all the algae and seem to be doing fine. im planning on getting 2 more turbos, 2 emerald crabs, 10-20 astraea snails, 10-20 more hermits, a sea cucumber, and a green lettuce nudibranch. i already turned the lights back to MH-6hrs and Actinics-8hrs. i only have two corals that are pretty much dead due to the algea and they arent attached to any LR so i will start scrubing the LR soon and get that clean up crew.
