how long between treatments

a little long, but heres the story: i got a niger rigger and a clown tang and added them to my tank that housed a lunar wrasse, foxface, matte filefish, marble star, and crabs/snails. of course the tang got ich and then it showed up on the foxface. i started using Kent RXP at half dose because of the starfish. did so for 3 days and noticed it wasnt affecting the star so i uped the dose to full for the next 4 days. i did have my carbon and protien skimmer in/on the system during treatment Rxp intructions say to leave skimmer on so that the dose gets taken back out. the ich apperd to be going away the tang was eatting (wasnt at first) just a couple of spots left. i also started for the first time feeding the tank live feeders for the trigger and wrasse. the trigger never stood a chance the wrasse ate 3 feeders at one time. so i stoped putting them in for the night. the next day i noticed my lunar wrasse staying in his per-say bed (WW2 carrier decor) and he had cloudy eyes and stoped eatting. now 5 days into the RXP treatment i found my filefish stuck to the powerhead intake after coming home from church, he was alive and fine after i shut it off. he swam away on his own, was super spooked and just hid for the next day but alive. the next day i noticed where he was stuck had turned white size of intake tube, not fungus just his skin color as if it was a bruise. i suspect a internal injury. so i started using Melafix for filefish and eye problum with wrasse (still using rxp for the next 2 days, talked to trusted fish store manager friend and said he thought it would be ok to combine due to the melafix being organic) the filefish did start eating myysis again. the next day the white spot transfered to the other side as well. (used rest of rxp, ended that treatment but still using melafix for next 6 days.) After ending treatment with RXp i did a 10% water change and stoped using skimmer and took carbon out of system, added strees zyme as always when i change water. the next day the filefish died and my tang started to turn black were he has blue (lines) and his face was extremly sunken in. (this entire time i have been doing bi-daily water tests, everytime they come back perfect except NO3 usally about 10ppm but thats not toxic enough to even kill the inverts. anyway the next day the tang died, (had about 12 days total). so for about 7 days the wrasse hasent eaten after eating those 3 feeders at one time, and still stays in carrier most of the time , but when he does come out he satys right on the bottom of sand bed and bumps into things, i suspect hes going blind but does not have cloudy eyes. maybe the rxp (pepper treatment) damaged his eyes or maybe it was a combo of the rxp and melafix. regaurdless what was done was done, but i was finally done with 7 day treatment of melafix , so i did a 15% water change and started up the skimmer and added the fresh carbon. the next day did another 15% water change, and noticed the warasee comming out more and swimming into different aeras, but still bumps into things as if he can see some, so maybe half blind. was the melafix keeping him blind? i asked myself. so the tank has been going with no chemicals for a week now, water test shows perfect. the wrasse finally took some raw fresh shrimp chunk, after holding it right in front of him 4 days later, so hes eating again. but now i see the cloud coming back in his eye and the foxface still jerks his head from time to time (started when i used the melafix).
still have sick fish, wrasse half blind with cloud in his eye and the foxface jerks head and shots acroos tank. its been 7 days scine any treatment has been in the water, carbon in and skimmer on the system. still perfect water tests. so the querstion is how long should one wait between treatments? i plan on using primafix this time for treating a bacterial infection (wrasse eye)
AND HERE IS SOMTHING ELSE TO CHEW ON. this whole time my sump for DT that houses a watchman goby and a perc clown (wrasse tried to kill both of them months ago) with no problums at all? and also 3 days after doing last water change my marble star has started melting. with better water and no chemicals in there? WHAT THE!! i thought it would have 2 weeks ago with the rxp. why the long delay i wounder. i know all of this probly could have been prevented if i had a QT but i dont. on the good side on snails and crabs are loving the fact the wrasse is blind, havent seen so many of them out at one time in months lol. thanks for the help.

It is always a bad idea to treat with medications in the display tank, especially since the med won't work anyway. Turning off filters compounded the troble threefold.
Do you have live rock in that tank? What fish are left?
