Being new to the saltwater side of the hobby I thought it would be great to post as I make way along to not only learning about keeping a marine tank but the steps as I work my way to finally owning my own cephalopod in the future. This will helpfully also be able for me to get tips from everyone as I post my progress so I can learn as I go. :) So please-feel free to give me any tips or advice as I always appreciate it. I started out with what I would recommend anyone doing is lots of researching, reading, chatting with fish stores. This allowed me to see if this next step was something I was ready for as well as would be willing to take on the challenges that come with it, and I will say that there have been a few for me already. I was fortunate to find a somewhat local fish store that specializes in salt and marine tank. I am going with a smaller sized tank though it is not recommend to go anything less then 30 gal as it can more difficult to maintain. Fortunate for me biocube tanks have come out with some nice tanks. I went with one of theirs. For beginners like myself I did find this book to be helpful in learning about keeping saltwater tanks in general: https://www.amazon.com/Marine-Aquar...ne+aquarium+handbook+from+beginner+to+breeder I am going with a smaller tank with the hopes of down the road getting a smaller dwarf sized octopus or cuttlefish. The first big difficulty I ran into so far has been getting my tank drilled. The point of drilling it was to attach my display tank to a sump and a skimmer. The majority of glass retailers out there are not all that willing to cut them for you. The one I ended up going through ended up cracking my tank and making a real mess of things. A bit frustrating. On top of this-my live rock and sand was starting to dry out due to how long it was taking to get the mess figured out. So it was back to the drawing board you could say-I again am lucky to have such a great local fish store who not only helped me purchase a second tank they then drilled it for me. The next step was setting up the tank. Due to being new to this I did pay to have help here. Which I will say I am glad for as after seeing how to do it-which I probably could do it now on my own, I doubt I'd have been able to figure it out so smoothly without someone showing me. Naturally with any first tank set up it will look quite dirty in the water until it has a chance to settle down. Once settled it was looking rather spiffy. :) I am using the biocube stand with it. I will point out that there are not very many rocks in the tank-for an ceph they will need a lot more then what I have. But I am working up from a beginner so will be trying my hand at a few hardy critters first then some coral and work up to a ceph! Another small challenge to note: I had a power strip I used that had timers on it but was very difficult to figure out when it was on versus off. Well-I thought I had it set right until water started pouring out from the sump. After a moment of panic- I figured it was because one of the power ports was set to its night setting turning it off while allowing the other pumps to continue. So lets just say I dumped that power strip out the door. Pretty tired of messing around with that thing. Currently my local fish tank owners and I are working on getting a stand for the skimmer as it is sitting a little to low then we would like. We also will be changing the piping on the side that is currently cycling the water due to it makes opening the full hood difficult. But it has the tank up and flowing.
