So, to start off, I'm new here. I had an account years and years ago, but I lost interest in the hobby once I got into high school, and sold everything off. I had been in the saltwater portion of the hobby for my whole life at that point, and I was tired of it. Recently, I was browsing Craigslist, looking for a used tank for my nephew. I came across a 10 gallon tank that was fully set up as a reef aquarium, and long story short, I ended up grabbing it. In the ad, it had said that it was a bit of a fixer-upper, with two fish, no coral, and just a few crabs and snails. It came with everything else that was needed. Turns out, that was an understatement. The tank was covered in algae, and nitrates read over 80 PPM with an API kit. When I got the tank home, I cleaned up the front panel, the sand, and the filters. Then, I did a 100% WC, and re-acclimated everyone. The tank is ugly and still a bit cloudy, but it's safer for the inhabitants now. This is what came in the tank: 2 (small) Lyretail Mollies 6-8 snails, mostly dwarf ceriths 1 Hermit Crab (that I can find) 1 shriveled up zoa colony and a mystery macroalgae. I realize that the mollies will need to be rehomed at some point, but I'm not aware of any stores around me that'd take saltwater mollies. I also realize that I'll need a larger CUC, but I want to wait to make sure the tank isn't doomed before shelling out for that. As for the coral and macro, who knows if they'll make it. They don't look so good. Equipment-wise, it came with: An AC 20 HOB An Aqueon 50W heater An ABI PAR 38 and I added a powerhead I had laying around for some extra flow. Forgive me if I'm forgetting any important details for a thread like this, but I'm jumping back into the hobby head-first. I'll use this as a sort of "tank journal", as well as ask any questions I may have here. Thanks for reading! Pictures to come.
