I have been reading this website for months & have had a tank preparing for my future Octo. There seems to be very little consensus in regards to proper water conditions. If someone could please list the proper ranges for all the water parameters it would be greatly appreciated. One of the things that concerns me is temperature. I have seen much discusion about keeping water temps lower than normal tanks (closer to 70f) but when I look through the member tanks many of them are in the high 70's. As a side note, my local pet store jumped the gun on me and my Octo was special ordered already & will be arriving today! Please help me not kill this thing :?
