Okay, so tell me what you think here. My plan for the next acclimation is this: I will have a 2.5 gallon tank sitting inside a 10-gallon tank, with an airstone and a bag of carbon. the octopus will be placed in the 2.5 gallon initially with aeration, then drip acclimation will start. I'll place the bag of carbon on top of the airstone to draw water through the bag, pulling out excess organics in the water. When the 2.5 gallon is full (I'll make that last about 1.5 hours), I will remove half the water in that tank and continue drip acclimation for another hour or so, then allow tank water to flow into the 2.5 gallon at whatever rate an airline will allow it, overflowing the 2.5 gallon until the 10 gallon is close to full. Then, I'll remove the 2.5 gallon from the 10, and place it into the 75-gallon, allowing the octopus to leave at his own discretion. This acclimation should consume all of around 3 hours and he shouldn't notice any change in water chemistry, nor will he be disturbed in any way when I add him to the tank. Maybe this seems like a little overkill, but I lost the first one, and I don't want that to happen again. If anyone has any pointers as far as how they go about acclimating, let me know, it would be much appreciated. I want this shipping/acclimation process to be as stress-free as possible.
