Introduction: Hey R2R. While I've had some freshwater tanks over a decade ago and I worked for roughly two whole months at a non-bigbox LFS, I have otherwise no experience with saltwater tanks. I will say I did learn a bit at my LFS period as they serviced tanks and did a lot of saltwater business, but I am otherwise new to this hobby. I stumbled upon some YouTube video one day which reignited my interest in the fish hobby in general. Background: As alluded to, I had a 45 gallon little puffer tank back in high school/college. I like to think in working with brackish puffers, I did get a bit deeper in the mentality as opposed to just having a goldfish or something. I even had a small snail tank to make puffer food, lol. But for a variety of reasons, I fell away from the hobby and sold my setup to a friend. Fast forward some years later, I began down the rabbit trail of information that is involved in this hobby. The complexity and depth involved in this hobby definitely drew my interest. I definitely have other hobbies and responsibilities that consume a good bit of my time so as I kept down the rabbit trail, I pretty much resigned myself to thinking that this can be something I will get into maybe in a couple years when things calm down. One night, in casual conversation with the SO, I mentioned the idea of doing a reef tank in the house, something big that would make an impression in the house. Much to my surprise, she was into the idea, almost excited about it. This was all I needed to decide this was going to be a thing I was going to do. I also decided I didn't want to start small and upgrade along the way as I didn't want to end up with a ton of tanks and equipment which ultimately would be stored/sold. As I said, I am familiar with hobbies and how they tend to go. As such, I decided to get an adequate sized tank on the front end. And that puts is where we are today! The Plan: As the title indicates, I have placed an order for a (72"L x 30"H x 24"W) tank with Custom Aquariums/Lifetime Aquariums almost 2 weeks ago. Some tank information and dimensions (not drawn to scale) are below. They advertise it as a 240 gallon though, after glass thickness, its more like 210 gallons of water. Tbh, I'm not sure the correct "tank size" to call it so I went with their convention. I'm told the tank isn't expected to be delievered until late April, so roughly a 3 month wait. But I have plenty to catch up on other obligations as well as need that time to make plans so I'm not bothered. I'm making this thread for a few reasons. Being new to this, I 100% want feedback from people who know more than I do. I am fortunate to have a good bit of time available to do plenty of research. I intend to write-up my ideas as I prepare for the build. Hopefully I will get some good feedback and save myself some time and money by avoiding some mistakes. Also, it'll be good to document my thoughts for the future me to come back to as I am apt to forget some detailed thoughts from time to time. Conclusion: Anyways. Thanks in advance for anyone who bothers to check this out and/or provide any feedback! Unfortunately I'm sure some juicy photos of reef gear and actual build progress may be slower as I have a lot to learn still but hopefully it will progress nonetheless.
