Sodium Thiosulfate

5 pounds? in what form? pure that would probably dechlor a large lake!

Only works on Chlorine... will break the bonds of chloramine leaving
free ammonia.

With Chlorine it forms NaCl (salt), salt will cause ammonia to be
released from many of the binders used to hold it (like the Ammo-chips
sold for aquariums ... not zeolite what is that stuff really called?)

Anyway all this is to say...If present ammonia should be dealt with
and tested before and after use.

I had no idea it would break the bonds of Chloramine. I hope everyone reads
this post.

I'll be leaning on the bus stop post.

The use of Sodium Thiosulfate does break the bond on chloromine and ties up
the chlorine part so it works to remove chlorine. I use it all the time as
a dechlor. The amount of ammonia in the chloromined water is nearly
negligible in quantity once in the pond and if the filter is working
properly, it will be removed along with any other ammonia generated by the
fish post haste. Now if the quantity of water change is large, 50- 90% I
would use Amquel, which I also stock. I use Amquel when the fish spawn,
since I get a very high ammonia spike that lasts but a few days before the
filter takes care of it, but I don't want any damage in those few days. I
bought my Sodium Thiosulfate from AES also, but a 50 pound bucket. Maybe I
will need to buy another in 20 years or so. Use 500 grams per gallon of
water and it will treat about 20,000 gallons of pond water.

How do I measure grams without a gram scale? Using a tsp. would not be
accurate because of the density/weight of different substances.

I use a small digital postal scale, but before that used a weight watchers
scale. Just went and measured in a measuring cup and 500 grams of sodium
thiosulfate is almost exactly 2 cups.

Thanks Rich. :-) I think we do have an old postal scale in the back
office.

actually it is preferred to fill a large tub with a known amount of water and then
use 1/8 teaspoons to work out what is actually needed for neutralization. I then
double that amount. sodium thio is safe at 10X the needed dose. Ingrid
