The other information you need to know is how much will it cost you to keep it running!
We saved and got a very nice 250 set up, completely custom and hand made - not cheap.
What we didn't think about is how much the monthly electric bill would be with a system like this running.
The system includes the following equipment:
3 - Little Giant 4 pumps (running 24/7 of course)
4 - 250MH Lights (each lamp runs 6 hours a day - they overlap to simulate the sun)
8 - Canopy fans (runs 10 hours daily)
1 - 1/3HP Chiller (guessing about 10 hours daily)
My monthly electric bill increased by $175 (So California Edison - your rate will vary of course)
My additive bill (B-Ionic mainly) increase also.
Big tank means more livestock - monthly food bill will increase!
I would say this tank cost us about $200 a month to keep running.
Just some more info for you to prepare for!
Good Luck!
