Somy tank has been offically cycled for twoish weeks. Still been feezing it ammonia and getting plants in. My temp is still at the cycling temp of 30c. So i need to start getting my temp down to 26c ready for fish. However, i have read two conflicting stories. 1 - turn the tank to 26c as soon as the tank is cycled or when you are ready to stop feeding and add fish 2 - turn ut down slowly over days or you will ruin the cycled tank and BB could die off due to sudden temp drop. I also read someone who turned it down in one go had nitrites reappear at 0.25 to 0.50 and as soon as the temp went up. It started cycling perfectly again. What is the correct here??
