sodium thiosulfate

Where do you buy it and how much do you use?


I just ordered it from http://watergarden.com and it has directions on
the
label for the dosing. I think I've read on here that it's
easiest to make a "stock" solution in a jar, but for my
3500 gal pond, I'll probably just dissolve some in pond
water as I begin adding water.

A lot of sources suggest making a "stock solution". What they don't tell you
is that as soon as you mix it with water, it starts to deteriorate, and is
no longer "fresh". It is pure ST, and has no stabilizers. You're much better
off - as you said - mixing it in a bucket of pond water and tossing it in
as you need it. Off the top of my head, I think 1 tsp. will treat 500
gallons. I usually refill my pond after a water change by stuffing the hose
in the skimmer box, next to the pump intake. I just toss the dry ST right
there, and let the hose mix it in with the water. Just remember: it *ONLY*
treats chlorine, not the ammonia portion if your water supply has
chloramine. In 10-15% water changes, it gives your filter an extra dose of
ammonia on which to feed. On larger water changes, the ammonia issue must be
addressed or you can put your fish in danger.
