Hello everyone, I have two 50G tanks in my system; one to house the (future) octopus and one for water conditioning. In order to minimize escape options I have only the overflow box and the water inlet pipe in the animal tank; my filters, chiller and protein skimmer enter and exit the second (water conditioning) tank. It occurs to me however that it might be better to have the protein skimmer pumping water directly from the animal tank, in case of inking. What do you think? I really appreciate all the trouble everyone has taken during my previous posts. I'm sorry if I'm asking stupid questions, but it seems a waste not to pick your brains, given all the collected expertise available here! Thanks in advance, Lene.
