Rob2718 Posted February 20 Share Posted February 20 We had a cycling disaster after using the trio meds on our newly purchased discus. When the discus arrived, we slowly acclimated them to the tank water and temperature. The 30 gallon tank was filtered with a Fluval 407 that was full of fully cycled media. The next day, we added a single dose meds (Fritz Paracleanse, Fritz Maracyn, and IchX) at the recommended dosages. A half day later, the tank crashed hard, the water was cloudy and all the fish were lying on the bottom dead or dying. We changed most of the water, and added two 80 gallon sponge filters (also fully cycled) and the tank and surviving fish recovered (but many were already gone). Now the fish (plus some replacements) are thriving, in a 75 gallon tank filtered by two fluval 407's plus an air stone for extra oxygen (without it they are gasping). Tank temperature is 85 degrees, and water changes are done daily due to the high amount of food they are eating. Now the question. Most of these fish have not been treated with any medications since we purchased them. We would like to start them out parasite free, but do not want another cycling disaster. Is there something about the setup (high temperature, bare tank, canister only biofiltration) that makes one or more of the above medicines ill advised? Would you recommend skipping preventative medications entirely, or modify the treatment somehow? What could have gone wrong the first time and what should we do differently this time?
