I treated my tank for fluks after stressing a flame angle so much it didn't make to more than 1.5 days. Catching a fish in a display tank is not prity even with 90% of the rock out. Prazi-pro works it only afected my pink tip Nem but it has bounced back. I will not try and catch a fish in the DT again treat with prazi-pro it will rid the tank of flate worms fluks, ancor worms, tape worms and Turbellarians. instructions say to add 5ml per 20g I did 4ml per 20g then wated 2 days and added the other 1ml per20g and added 1ml each day after to manetane level for the full 7days. then do a 25% water change. then your back to normal remember you have to remove any carbon stop skimmer and UV. I put my skimmer on after 5 days for a couple hours and if liquide was clear returned it back to the sump. remember I have a low bio load in my tank and I keep it that way in case of power failures and outher unforseen situations. I can't stress this more get a good skimmer and UV sterilizer make all the difference when it comes to things like ICK and other bad bugs that have a cycle.
