I built a 160 gallon FT and three 90 gallon growbeds from WFS for a client. It includes a Danner 9.5 pump from Amazon.
Total price tag for this turnkey system including labor is $1k.
Washing the cinder still not my favorite part btw. I washed all 270 gallons, 5 gallons at at time in about 3 hours. BTW, 1 cubic meter of cinder from Niu Valley equals exactly 270 gallons.
