Update, I had a small setback. One of my SPS corals started to STN and then my LFS helped me out. Picked up Eco-Balance Dr. Tim's solution marine safe bacteria. It is suppose to help defend against the bad bacteria that entered my small 12 gallon system. I brought home 3 corals from Reefapooloza Orlando, and I didn't dip them. Well the STN spread to another one of my SPS acros and then RTN hit overnight. I was able to use my bone crushing sears and save what I could by fragging the strong pieces that had not been hit.
Next, I placed Dr. Tim's solution and shut off skimmer, UV and removed all foam and charcoal. So far, just one dose is all I got in and will repeat it one week from when I started. All is looking much better and RTN has stopped and STN looks like it is in check.
Also, I inherited by brothers 12 gallon identical tank to mine, his is all LPS corals only, but we both run same components: AI 16 HD prime fixtures, Chill Solutions chillers, Coralife 5 watt UV, Gnome glass skimmers, and we run the same media in our basket with Innovative Marine cheato 9watt LEDs, Sicce return pumps and Nero 3's for water movement.
Now, I have two 12 gallon systems on each side of my dinning table. Here is video of my systems, they are 5 months young and still going.
I will keep all updated on the STN and RTN of my corals using the Eco-Balance solution.
