Yeah I didnt think of how disorienting it would be especially going from dull unnatural light back to sunlight. He is probably telling stories how the big creatures abducted him, kept him in a small puddle and just stared at him for days. Poor guy But yes he is acting normal and eating very well.

There are several different ways you could go at it. If you want to keep it easy to convert back to "swimming pool" and keep the cost down for both factors, here are some suggestions. Leave the color as is, the blue isn't that big a problem with algae and a black swimming pool might not be as easy to sell. Some shade for the pool will help against the algae as well as would having it coated in black. Let the water age to get rid of the chlorine. (What source of water do you have for re-filling if you were to need to do any water changes? If you have city water with chloramine you might need to look into some water conditioner.) What is your existing pool pump/equipment? In some arrangements, you could simply continue using the existing pump/filter. Or you could shut down and drain (like for winter storage the pump and sand filter, if you do this properly, the equipment can be hooked back up when wanted for a pool again.) Then you can get a submersible pond pump and a bio falls basin. Put the pump in the pool and hook up to the bio-falls basin sitting on the edge of the pool and you are set to go for small numbers of fish. Add some aquatic plants (make sure they are in large plant baskets with gravel, no dirt.) Place potted plants around the falls tub to dress it up a bit and away you go. Now this might not turn your swimming pool into a perfect ornamental pond but it is the cheap way to do it. Make sure to choose an energy efficient pump as you will probably be running it 24/7. In warm water you need to keep it flowing or the fish can run out of O2. It is best to start out with smaller numbers of smaller fish and keep the feeding light until the system has stabilized. Now if you want to make it really fancy, it will of course get more complex and costly. If you want large or lots of fish, then you will definitely need to learn more about Aquaponics, bio filtration, fish keeping etc. Here is a link that might be useful: www.TCLynx.com

Yes, I agree with the liner. I would reccommend a Koi specialist come in and transfer the Koi to an oxygenated invironment while the pond is drained and the liner can be installed. Put in some new air stones with an aerator. If it does not have a UV filter, I would reccommend one of those as well. Roots are OK for decoration as long as they are bleached by the sun until dry and gradually introduced into the invironment.

He didn't make it, but thank you for the suggestion . I found that site after not getting any response from here doesn't seem like there's that many people here.
