hi everyone thank you for your time in advance. my problem is the area i want to install my pond is watered by my sprinklers with city water, ie chlorine and all the bad stuff that we try to get out of the water. is a little bit of water a day ok? the pond is only about 50 gal. i would like to be able to put some goldfish in there but i dont want to kill them. would i be able to just add water conditioner once a week or something? any ideas would be great.
