creepy is what it is... looks like a mix between a tape worm and earth worm. I imagine the fat end having vicious chomping teeth. But I have no idea what it is.

It is a peanut worm, I have had them in my tank before without any issue. They are actually pretty interesting to watch.

my pipe is all pvc. copper would be deadly. i have not hooked my storage tank into a cooling loop but i am giving it some thought. i think a titanium heat exchanger on one of the tank returns and then a controller turns on the pump on the closed loop through the storage tank. presto two uses in one.
i have a closed loop with tankless water heater and heat exchanger for heating my 20,000 gallon koi pond.
something similar could be used for cooling as well.
i'll see if i can find a picture.

Most geo-thermal loops are made of copper coil and run through a titanium heat exchanger. The tank water passes throught the heat exchanger and the heat is transferred so-to-speak.
Usually the tank water is running through all the time, and when called upon, the ground loop is activated to circulate cool water through the exchanger.

For a tank you can use copper, but only if you are using a heat exchanger made of a salt resistant material like titanium. In this application, the system water does not contact the copper or ever travel below ground.
Other geothermal systems push the system water through poly proylene U tubes or coils that actually carry the system water below grade and back to the system. Which you chose shoud be based on your system and the efficientcy of the pumping set up.
I think most people find that heat exchangers are more efficent, but not always. One issue with running your system water below grade is that during times of the year when you don't want cooling, you still have to circulate the water to keep it from going stagnant in the below grade plumbing. Not to mention all the critters that grow in that pipe just like in your drain and return plumbing. Yieks! Imagine cleaning that ever so often?

Can you detail your plan for the doors on your light tunnel?
I will be installing a tank with the same footprint as yours and my roof is roughed in for two 4'x4' skylights.
I am thinking of a single door about 18" tall that runs the width of the tank with 8 or so plastic hinges. Then a catch would hold it in the open position.
Great thread, thanks.
