Yes I did. Used it in my DT. Only problem is my skimmer went crazy so I had to turn it off. I performed alot of water changes as well since the skimmer was off. When you change water make sure you replenish the Prazipro by the amount of water you took off.
Dose 1/2 Praziprio,wait a few hours and see if the fish are feeding. If yes then dose the other 1/2. If fish are still eating then you are safe. If not then run carbon, water change to get rid of the Prazipro and start again but with smaller dosages
