Hey y'all, I just found out a friend of mine has a Marineland System 12 lying around that he's not using, so now that I've gotten a hold of it I was thinking about converting it to a nano setup. I'm only looking to have FOWLR, as the compact fluorescent 50/50 actinic is only 13W (I doubt I could even keep the lowest of light mushrooms). Probably just a clownfish and a goby or two, and maybe a shrimp or crab. Now my question is what would I need to convert it. I don't mind doing weekly PWC so I don't think I will need a protein skimmer, so I figured I would need a hydrometer, and maybe one more small flow pump (I've read the standard flow is inadequate even for FOWLR), and probably a small heater (although I live in South Texas and my house is always around 77-80 degrees, so I am skeptical about even having to buy that). Aside from that I was going to buy some crushed coral sand and maybe 8-10 pounds of live rock for it, and let it run for a couple weeks. What do you guys think? What else do I need, and do you think it's going to work for me as a nano cube setup? For now I'm only going to buy the replacement bulb, a hydrometer, maybe a flow pump, test kits, and salt mix (preferred brands?), with some live rock and sand. If you guys really scold me I'll get a small thermometer, but my current community tank (also a marineland 12) does just fine without a heater, and stays consistently between 75-80 degrees). I'll look into getting a small protein skimmer if you guys think it's a good idea but I would only go for something like the Fission Nano protein skimmer. I haven't tried saltwater yet so i think this would be a cool way to get my feet wet without spending a lot of money. Tell me your thoughts though!
