Water chemistry, new pond, new ponder

Oh, I'm an excited new ponder. After a month of recovering from a
back injury (due to digging out my 400 gallon pond!), I put in the
liner & water, ran the electricity and turned on the pump. The short
waterfall with small veggie filters isn't running yet, but the pump
pushes the water through the Oase pressurized filter. No koi planned,
just goldfish and hopefully frogs.

Questions: I live in San Francisco, where we have chloramine in the
water. What do I use to counteract it? Can you recommend a good
water testing kit? How often should I test? If I add more water to
compensate for evaporation, do I need to add more chems to nix the
chloramine? How long before I could add fauna?

Thanks...
