Looks nice Chiefmojo. Filtration seems to work flawlessly, are the 55 gallon tanks you talked about the drums in the photos. I have access to some that I considered using for a sump setup on my next large tank.
Hey jer, since your water has a yellow tint to it I hope you buy bottled to drink.
Chief-according to my calculations you have about 1100 gallons!!! 150x40x40 is about 140 cubic feet @ 7.48 gallons per foot3 is 1071 gallons!!! what a monster!
I come up with 1038 with the given dimensions. 150x40x40=240000 Cubic inches, you get the given gallons by dividing this number (240000) by 231. Giving you 1038..... gals.
Still, it is a monster that I would love to have.
