I would have to say it will probably be going somewhere in the backyard where it has kind of like small rock on it. There is only a little bit of grass and like this red brick thats about 12x12. I was planning on finding a spot out there that the 18 feet will look good at and probably dig down a little bit and sit the pool in side of the hole. Would it be good to line the hole with something before I put the pool inside?? Would it be ok to maybe use tank sealant to hold the rock togeather?? I would love to be able to keep a few cats but would hate to come home and find all that water in the backyard and a bunch of dead fish. What would you recommend to keep in there Dr. Joe?? Also since I do live in AZ would I need to run a heater in the summer since it usually doesnt get below 70 degrees here at night durning the summer and about 100+ during the day. Also I have never kept peacock bass or red tails in the past but would it be ok to keep larger cichlids with them as well?? Will they do ok with the weather? Thanks in advance.
Digging the pond into the ground will help regulate the water temperature, the deeper the better. dig down atleast six inches the add 3-4 inches of construction or play sand and level it out like you would concrete. This will give you a base to protect the bottom from growing grass and punctures when you walk in it for maintenance (and not to chase the fish, no matter how much fun it may be).
Tank sealant is perfect for glueing rocks together, G.E> silicone ! without algaecide (mold suppressant) is the same and is way cheaper that that from a lfs.
I mentioned the problem with the cats to bring it to your attention, the holes they can make are vey small and are bothersome at most. more so for an indoor pond because of mold build-up. As me_we_todded(again too long of names

) said, it would take forever to leak down, the new vinyls don't split from a pinhole.
You shouldn't need a heater in the summer, that much water will stabliize the temp pretty well. You can purchase sunshade material from HomeDepot and make a cover down the middle of the pond 6ft wide and it will shade part of the pool all day if the pool is orientated right (east-west for shade in the same spot all day, north-south for moving shade). Floating plant (lilies and even duck weed (some fish love to eat it)) will help with temp control too.
Pbass should be ok but I will defer you to Juan Jamad as the resident expert on them, midnight just put his in his parents pond (they had beat up on each other alot, but were in a relatively small areacompared to yours). Anything you keep with pbass has to be the same size or larger (and keep the fed).
There are a couple of cat experts on here , a name doesn't come to mind right now, just post the question, they'll find you.

also what would work good to keep down on the algae as i would assume it will grow very rapidly since it will be in the az sun??
Keep feedings low, good bio-filtration and lots of plant to use up the nutrients left in the water as fast as possible. A UV sterilizer for this size pond is a little pricey but well worth it.

Nice choice.
Have you tested your tap water (or do you have a well?) to see if added chemicals or other water treatments maybe necessary?
I remember in some communities the fire departmet used to come out for a small fee and fill up pools (faster). Just a thought (@ 5g a minute vs a fire hydrant it's worth a call

).
