24' diameter pool ($2500)
You could possibly use the pump from the pool as ciruculation or get two running for nice cross current. ($250 each)
Use the sand filter as a refugium with lr
instead of sand ($260 not including lr
Cut out a section of the surrounding walls and replace with thick acrylic panels. ($????)
If you could get the water from the ocean that would be great, save lots of $$.
You could build the top of it like a small flat roof (1/4" /ft. slope) with skylights 8-10 skylights. ($????)
Not as unrealistic as people thick just cost a lot of money. I would say about 20k for just the setup not including lr
. probably looking at about 20000 gallons of water so about 50000 lbs of rock. If you are truely serious about it, do contact a place like sea world or something similar that would be able to point you in the right direction to success. If you do this make sure we get pics and plane tickets to come view this amazing feat!!!! Good luck!!!!
