I have no bottom drain at this time. I think the pooh just sinks do the bottom and slowly dissolve over time. They do have rather large terds though for birds. In fact reading in the encyclopedia brittanica the mute swan, the bird I have, is the heaviest flying bird in the world. These are the same birds you saw in the story "The Ugly Duckling". They have that black knob on there nose. Beautiful birds, they hate humans though. Nobody here knows what they would do in my situation though huh.

Well lets just pretend there are no birds in there pooping. For a normal swimming pool do you need a bottom drain. Or would what I have at this time work. Thanks

Anytime you have an extra heavy dirt load on a pool, a bottom drain makes maintenance easier, and improves circulation. In your situation, I think those factors will be pretty important.

The alkalinity won't be a problem, if you have a waterfall. If you maintain a pH of 7.2-7.4, the waterfall with remove most of the alkalinity (via aeration) over time. But, you'll probably have to add a lot of acid.

I'd recommend that you consider an oversize DE filter, like the large Sta-Rite models. Since you may need to keep chemical levels down, the extra dirt removal capability of a DE filter (compared to a sand filter) may well be significant.

Ya, I will have to keep chemical levels down sense the birds will be drinking the water so the chlorine will have to be kept down to a minimum. When I shock every know and then I'll have to do it while there out and fence them out for that time until levels drop to normal. There is already a fence around it with a gate that I open everyday to allow them to roam in the yard. Anything you or anybody else would like to add would be excellent. Thank you

Don't be too concerned with some chlorine that the birds will drink. I went to an airshow once and the water they were providing to drink out of a tank truck had the most God awful smell of chlorine that I had ever tasted in "potable" water. It was safe to drink but was not pleasant to taste.

Anybody here know of any automatic swimming pool cleaner that would work in my application. The liner is a polyethylene type and the sides and bottom aren't true. Not to mention there are crinkles in the polyethylene liner cause the liner will not lie flat. Most of these crinkles are on the sides of the liner cuase the liner has to curve up on the sides. thanks
