Wow, I understand your frustration! I had estimates up to $10,000.00, and could have purchased used stuff for half. I visited every LFS on LI, and most in NYC, but I couldn’t get delivery, pick up only. I did purchase a 180 gal with everything, delivery, and set up for $4,000.00. Delivery and set up were no charge. Brooklyn Zoo Pet Store, Brooklyn, NY, ask for Peter
If you want to go cheap, under $300.00, it’s very easy, and without any expensive equipment, but no corals yet.
60 gal tank—————————- on sale...........$60.00
Lighting............................Basic T-5..................$100.00
Filter..............................Aquaeon 75................$60.00
Extras, maintenance stuff, food, test kits.........$60.00
No heat, no skimmer, no power heads, no dosing, no expensive salts, no RO, and no fancy anything.
Just need access to saltwater. My yearly costs are $60.00 ( filter pads ) + electric + gas to collect.
