Let's try to round mine out....
$350 - 38 gallon tank, stand, and full lid/light fixture
$40 - 20 bux each for better light bulbs, 1 10,000k daylight bulb and 1 320nm Actinic blue bulb
$50 - Air pumps, hoses, air stones and valves
$200/$250 - About 60 pounds of live rock (shipped FedEx)
$50 - 30 pounds of Aragamax sand plus 20 pounds of Arag-Live (live sand) to seed it with
$100 - 1 Yellow Polyp stony rock, 2 different mushroom rocks, and 1 Christmas Tree coral (which died, but I want another one!)
$150 - Assorted false corals
$40 - Penguin 200 bio-wheel
$20 - 200 watt Stealth heater
$40 - Maxi-Jet 1200 powerhead (adds current to the water)
$10 - 2 sheets of blue sided styrofoam posterboard. I used it to "blue out" the back of the tank. Looks much better than the fake backgrounds you can by, and by using this stuff, I didnt have to empty my tank and move it in order to paint the back side of the tank blue.
$20 - 1 tank raised Maroon Clownfish
$20 - 1 Diamond Goby
$35 - 1 Atlantic Pygmy Angel
$25 - 1 Fuzzy Dwarf Lionfish
$20 - 1 Saddle Valentini Puffer
$15 - 1 Hermit Crab
FREE - 1 Turbo Snail (snagged it from Jay's tank) HAHA
Oh and lets not forget the Test Kit, Food, water conditioners etc, and salt I buy every 3 or months, and the other assorted stuff....
$30 - Saltwater test kit (various necessary tests for water quality)
$100 (est.) - For water conditioner, pH balancer, medicine, Iodine supplement, Chroma-Plex, and all the other additives for the water, etc.
$50.$75 - Every 2-4 months for salt so I can do water changes.
$75 - For the other necessary stuff like nets, a hydrometer, thermometer, measuring cups, 5 gallon buckets (for water changes), siphon, "Mag-Float" (cleans the glass). and all the other crap.
Food is fairly expensive too. Here are the main things I feed all the fish...
$7 - Hikari Marine-S pellets
$8 - Ocean Nutrition Formula 2 pellets with Garlic
$8 - Tetra Jumbo Freezed Dried Shrimp (Krill)
$8 - Package of "Emeral Entree" frozen cubes
$8 - Package of frozen Silversides
$8 - Package of frozen Brine Shrimp
Liquids (for the corals and invertabrates)
$12 each for a bottle of ChromaPlex and ZooPlex (zooplankton)
Live foods -
$3 for a scoop of Live Brine Shrimp.
And my tank is only a little more than a "FOWLR" (Fish Only With Live Rock). I do have a few corals, but its not a reef tank. When I upgrade to the 72 gallon Bow Front tank, that setup will cost me a little over 709 dollars (the 72g tank, stand, lid, light-strip), and although it comes with a dual-lightstrip like I already have, I will be getting a 400 watt fixture with 2 150 watt Metal Halide lamps and 2 50 watt power compact Actinic's, so I can have some more corals like anemones and stuff. This 400 watt light fixture will run me about $500 alone, and thats if I get a deal lol. And I will have to upgrade my filter, heater, and add another powerhead when I get the 72g, as well as buy about another 200 dollars worth of live rock, and another 50 bucks in live sand to fill it out.
Did I forget anything? I have almost 1500 bux into this setup, and it costs on average about 20 to 25 dollars a month for maintanence/upkeep.
Saltwater = Not a cheap hobby LOL. I love it though...I love the fish and I love the maintence. With my freshwater tanks, I used to get lazy and put off the upkeep. Not with this...cuz its a serious investment ya gotta take care of ya money!!!!
