refilling pond

[al shookup]

I have a leak in my 500 gall butyl lined pond and am in the process of moving the fish (Rudd/ Tench and 2 goldfish to a temporary kids paddling pool. Before I put the fish back in the original pond, can anyone tell me what I should treat the tap water with and how much I need for a 500 gall pond?

thanks

not sure what they put in water there but sure some one should know and hope they can help .Guessing you have city water and it is almost always treated .Is there a place you could call there to find out
