Thanks. Want to figure out exactly how much bleach to use then Sodium Thiosulfate after.
Len what brand is it? Does it come in little clear crystals?
I use 2 teaspoons of solid sodium thiosulfate per 5 gallons of water to dechlorinate items that have been soaking in a bleach solution. If you are rinsing and draining and then refilling, I'd recommend 2-3 cups of dry thiosulfate for your 200g system. There really isn't any problem overdosing with thiosulfate either, but it's a fine idea to rinse it all out and get rid of it afterwards in any case.
