Hello everyone, I am starting up a saltwater tank to use with a Bimac octopus. I know that octopi are not for beginners, but I have had freshwater aquariums and have done a lot of research on saltwater, and would like to give saltwater a try. So I had a few questions: 1) How much cured live rock will I need, and where can I get quality/cheap cured live rock? 2) What is the best type of sand to use for an octo, or does it not matter? 3) What kind of filtration would you use for an octopus, and where can I get it? 4) What is the best live food for an octo, and what is the cheapest place to get this? 5) Where is the best place to buy a lot of deionized/distilled water, and which is a better choice for mix with Instant Ocean? 6) Will I need a sump, and what is the best brand and model? 7) Will I need a refugium and what is the best brand and model? 8) What sand depth should I aim for? Thank you for your time.
