| Thanks Scott and dick benbow,
It will take me some time to rearrange everything (mostly rearranging my ideas on paper), but keep in mind that pond is not mine, i am no koi expert and neither do i want to become one. I would just like to keep them in good health. As far as security goes, this pond has been designed for indoor IN A PETSTORE. I'm not worrying too much about kids drowning in there, the walls around the pond will be large enough to avoid such events and we have plenty of employees during the day to prevent that kind of accident.
i'll come back with some more ideas a little later,
thanks again
