Cold Water Fish Room

I wanted to expand my fish room (to let me see the fish and to have both cold and
warmer water species of killies), so I took over the integral single car garage and built
a real one outside. Was not big enough for a car anyway.
I had three objectives: (1) cold water room, (2) front view and eye level so as
not to have to lie on the floor), and (3) ease of maintenance.

To allow temperature control, I insulated the room on the outside wall with blue board
Styrofoam, and installed a thick insulated garage door. I installed an 8 k BTU/hr air
conditioner in the cellar window. Since I did not have enough warm water space, I
installed heaters in a few tanks to allow me to move warmer water killies into a
viewable setting. My stand design was to provide (a) face view, (b) viewable
height, and (3) accessibility for egg picking and cleaning.
Ross Cronkhite had a stand design that fit the bill, except his was 3 tanks high. Me
bein a bit shorter than him, I went for a 2 tank high version, and put a shelf low
to house egg boxes. I took a nasty fall onto my side in the other room while reaching an
upper tank standing on a real stable stepping stool (ok, so it was an old slide projector
with the adjustment leg up--OSHA never saw it and Id deny it).
Lighting in the new room is provided only by room lights, ceiling fluorescents, and the
standard for killikeepers, a good flashlight or two.
For ease of maintenance, I plumbed in RO water from the primary fish room via1/2 inch
PVC. I provided 3 ceiling drops with plastic valves and quick disconnects for water
changes, but since the main supply is in the warm water room, I will be filling a 32
gallon Rubbermaid garbage can which will house a pond pump to return the water to the
plumbing for distribution once it has cooled to the temperature of the new room. Just some
re-valving and another pump - no big deal. Air is supplied via 1.25 inch PVC from my 1/3
hp blower. Costs too much to run, but wow, plenty of air and pressure!
A 9 ft plastic hose is attached to the appropriate quick disconnect for filling any
tank in the room. Emptying is done into 1 inch PVC which goes out the basement wall to my
downspout piping (prevents overwork of my lousy septic tank drainage field).
The room is maintained at 68 degrees within a degree or two. For slightly warmer or
cooler water, I just select an elevation or modify tank covers. Finally, my ogoense are
laying well, the Diaptrons seem happy enough and the warm water fish can remove their
sweaters and start to work!
