Help! My landscaper accidently knocked a hose off my pond pump and
emptied 3/4 of the water. When I arrived home my fish were in a foot
of water, alive & swimming but I had to add water back late, last
night immediatley, about 1,000 gallons. I didn't have any
dechlorinator. Today I saw them swimming, water very murky but
considering the cool weather they should be lower in depth. The frogs
were above as well. Should I still attempt to purchase a dechlorinator
in the morning or is it too late? Have to test ph tomorrw as well. I
live in Morristown, NJ, temp is about 55 degrees right now. Have about
50 comets and 2 small koi.

I'd get the dechlor. You might have dodged the bullet this time, you'll
know come morning, but may not next time. ~ jan

Photographic film processing hypo is much cheaper and does the same thing.

Sodium thiosulfate (Na2S2O3) is a colorless crystalline compound that is
more familiar as the pentahydrate, Na2S2O3•5H2O, an efflorescent,
monoclinic crystalline substance also called sodium hyposulfite or “hypo.”

To dechlorinate tap water for aquariums requires between 0.1 grams and 0.3
grams of pentahydrated (crystaline) sodium thiosulfate per 10 liters of
water. (1/3 oz to 1 oz per 250 gallons)
