Hello,
First off welcome to R2R where you will find tons of lovely people and with that more knowledge then you will know how to handle. Everyone on here will definitely be honest and very nice and fair. We are all super glad your part of the family.
In regards to others and this setup, there is no way it’s a 10,000 dollar setup. Maybe they meant 1,000 but 10,000 I truly honestly can not see the value in that. If I was being generous, and nice I would offer 500 as my top figure. Most of the others between 250-350 are probably dead on. You could almost buy a new one and do the same set up for about the same price.
Most of us or hobbyists that have been in this for awhile will know what we are getting in a deal. He may try to sell it to someone who is new and doesn’t know any better. He could also do the same and say I’d take 500 for it. But, I suggest you test everything first, including it holding water. Please do your research before buying this. Ultimately it’s
Your choice and your money etc, but none of us here will lie to you.
What is your intent on this system your thinking about? Is it to grow and sell coral professionally as a business? Yet, do you intend to place corals in that tank first, then move to your display tank? Regardless, feel free to ask me for help or any one else of course. Good luck and welcome to the family.
Sincerely
Sarah
