Questions & Answers for 12020219s0008 Fish Rearing Tanks 2nd Edition 8/27/2019

QThe sidewall of the tank is to be34”
The Skirt on the tank is to be10”
TOTAL44”
Yet, underneath the tank there is a sloped bottom2”
Plus a 2” pipe and elbow or at a minimum of3”
Plus according to Q and A sheet, a drain pipe at least15” above the ground
That totals 20” below the sidewall of the tank or 10” below the skirt
What are the correct dimensions of the plumbing below the tank and the length of the skirt?
AThe skirt on the tank needs to be high enough to lift the bottom of the tank and provide for the sloping at the bottom of the tank and provide an elbow fitting for drain and still maintain a 2” clearance from the ground. With a 15” skirt to the sides of the tank and considering the 2” slope that still provides 13” of room for the elbow. The sides of the tank above the skirt need to be high enough to support a volume of water equal to 240 gallons.
QAre we to assume that the inside to be with fish compatible gel-coat?
AUSDA approved yes.
QSince there was no mention of inside or outside color, are we able to use what we have or can get for the best price?
AThe colors of the inside and/or outside should be either blue or grey.
QIs there any additional information on the clear lids that are mentioned in the specifications? Specifically, are you looking for acrylic or polycarbonate?
ARegarding the covers for the tanks, they can be either acrylic or polycarbonate, they just need to be opaque such that most of the sunlight is able to penetrate the cover. We do not need to be able to clearly view the fish through the covers.
QAlso, would they be bolted on through the flange?
AThe lids do need to be hinged such that they can be lifted to view the fish but they are not required to be bolted to the flange.
QHow thick does the fiberglass cover need to be?
Aat least .5 cm

Regarding the thickness of the tank, the tank is expected to be able to adequately hold 240 gallons of water and handle extreme changes in temperature (from -30 degrees F to 115 degrees F) in full sunlight without cracking or breaking down for an extended period of time. The thickness of the tank wall should be representative of this durability.
