Today I bought a 120G tank with stand and canopy. The person who previously owned it just couldn't keep up due to medical issues. He also provided 2x ToPlanet LED Aquarium lights that look quite nice but need to hang from the ceiling, which I cannot and really don't want to do. I would prefer to find a light that can be hidden inside the canopy. Can you all make any recommendations? He also gave me a doser machine which I've never seen before, a very large CO2 tank with 2 regulators, 2 wavemakers, and more. I'm going to snap some real quick pictures of everything he gave me for $700. I'm working diligently over the next few days to clean the tank and then I can get started on setting it up so I really need advice as far as what equipment/chemicals I may need to buy. He had 3 inches of black flourite (i think thats what its called) so I bought 3 Home Depot buckets and filled them up with that cycled substrate. It ALSO came with a HUGE FX6 canister filter that I kept the water and filter media in to help with cycling. There were a bunch of plants, some small neon tetras, a tiny puffer, and a few shrimp that he threw in a bag for me. The substrate was clearly overwhelmed with what look like those pesky pond snails so he recommended me adding salt to the substrate and leaving it to kill them, then washing it and putting it in the tank. Is that the best way to handle not getting them in my tank or should I just use new substrate? I would love to sell the 2x LED lights and get something that can be attached to the canopy or rest under it. Please help, I'm overwhelmed.
