Well I did confirm that I have red bugs and a lot of them I only brought two small frags smaller then a pinky finger nail of Miami orchid and tri color to a fellow reefers house Tuesday he has a really nice microscope you hook up to a computer and it has a built in led light ,well I have them you can see them very clear and thousands of posi babies running around on a small frag plug ....when I looked at the frag plug you could only see maybe two or three but when blown up 800x you could see twenty yo thirty large adults and like I said thousands of small red colored dots running around I am assuming those are babies.....so I did my first 23 mg sentinel treatment last night on my 90 gallon reef tank 120 gallon total water volume system....I broke the the pill up into thirds I removed the snails and crabs the best I could and one serpent star, now I couldn't remove my pair of coral banded shrimp ,a few crabs and snails stayed in and two brittle stars .....well I shut off the skimmer the gfo and then added the third of the pill which should cover 126 gallons of water per treatment they claim one pill covers 380 gallons of water ......so the results are in after 11 hours the shrimp are still alive the random crabs and snails are still alive not sure if that is a good thing....the other crabs and snails are gonna chill in a 5 gallon bucket with a heater and a pump for circulation for approx 3 weeks that is the recommendation from my LFS.... please let me know your thoughts im lost why my inverts are still alive although some say they lost all the inverts and some say they lost none ....thanks
