John, you did a really nice job building that tank!  I have a word of caution for you.  When you put the liner in take a lot of care to keep the edges of the liner above the water line.  I know that sounds like a no brainer, but it's very easy to fold the excess liner in a way that allows an edge to fold down below the top. Also when the water goes in the pressure will pull the edges down just a little.  So keep the ends long until everything is filled.  In your case you will not be able to tell right away if you have a leak, so this is very important.  

I found that by marking the middle of the liner and the middle of the long side of the tank was very handy for getting the liner initially positioned.  In my case I added rigid insulation to the inside of the tank as a soft liner for the pond skin. When I placed the insulation in the bottom I graduated the thickness to create a low spot in the tank so that the fish poop will tend to gather in one end.

Chris - Yeah.... No!   That box is NEVER coming out of that hole.  If this AP thing doesn't work I'm going to have to create a garden feature to cover it, or something like it.  Way heavy?   Nope!  Heavier than that!   I considered assembling it in the hole and in hindsight that probably would have been less dangerous, but this is a better story.

Jacques - What goes around comes around.  I deserved that one.  Thanks again mate.

John - your tank looks awesome!!  I was thinking though, you probably should sink it into the ground 8"-12" more...snatch it back out, dig a few more hours and voila!........JUST KIDDING!!!!  lol!  Hoping after such a productive day that you can take a joke....  Such a sturdy container, and it looks 'way' heavy, you and Jacques did a bang up job installing it!

This is a good day.  A bright sunny, highly pleasant, wonderful Arizonan winter day.

And.... the fish tank is in the hole.

A HUGE thank you to Jacques who came by to help wrestle the monster into place.  It really should have been a 4 man exercise, but with a couple of 2x4s and some engineering thinking we got the job done.

I still haven't got the liner installed, but that's nothing compared to relocating the beast.

Here are the photos.

Sheri,
I'm going to use Pond Skins pond liner which I bought from Home Depot. It claims to be fish safe and puncture resistant. In fact, right now I'm in the process of measuring it up for installation. I saw on one of the many forums that this is decent material but not as expensive as EPDM.

What's in lined with on the inside, John?

David, when water evaporates it cools. The water cooler (aka evaporative cooler, aka swamp cooler) cools the air only by blowing air through a layer of water and evaporating the water. We use it to keep the air temps down.

When the water in the tanks evaporate a certain amount of cooling (air & water) takes place. That's part of the reason water can be cooler than the air on hot days. So in a sense we can appreciate the evaporation that takes place.

I haven't heard of people using plants for oxygen; I would suspect tilapia would eat most kinds.
