Yesterday I bought a 65 gallon tank setup. And my first Octo! I setup the tank and got him situated. I used BIO-Spira enough to treat 95 gallons(Over kill for the 65 gallon tank), Live Rock, Live aragonite sand. The Nitrate and Nitrate are both zero. PH is perfect. but alkalinity is high. about 300. But the pet store i recieved him from was about 280. I am going to be monitoring the tank 4 times daily for any spike so i can change the water but i dont think It will spike. Im pretty sure the tank is cycled. My question is. I put an, in-tank heater in. It occured to me today that maybe he could cook himself if he sat on it....is that possible?! has anyone else had that problem? second i was wondering how do I feed him? Thanks for any help. I might have more questions to come too.
