Okay well first off, Im new to the whole saltwater thing, as I've never kept a sw tank before. But I've done quite a bit of research on the topic and with quite a bit more I think I can pull of a sw tank. Secondly, I've done some research on this site but I have a few questions that im wanting to get answered. Here's the idea I had. I really enjoy odd type fish, and the fact that octo's interact with there owner is just something that drew me to this idea. I've always been a bit afraid of the octo's when diving or something, you've seen the movie with the giant squid and such. But I know there going a lot cooler then I once thought. I was thinking, 55-85 gallon aquarium. 85lbs or so of live rock, sump filter, skimmer, and some basic lighting. The species I think will best suit me is a Bimac. I am basically dedicated to my Aquariums, the computer, and mowing lawns. And I think I have more then enough time to maintain a SW tank. Along with everything else I was also thinking that a chiller would be in order. Here are my questions 1. Im confused on the pump part of a sump filter. I couldn't find anything on the websites that sold them about a pump. 2. If I wanted to add a damsel to help cycle the tank how long do you think it would take. Would it still be the standard 3 months? Thanks for all your help in advance!
