I have a 39g tall tank and stand with heater and FW items with it I was going to sell to someone on my FD, but she hasn't gotten in over 2 months. I used it for brackish, I wanted to keep seahorses in it, being the perfect size and shape, but I barely have time for 1 tank, let alone 2. Was selling it for $125, but since you want it for SW and I don't have much SW parts to spare, would sell for $75.
