Bought 2 more of these 50lb pails of Sodium Thiosulfate. I tested my previous pail of the the stuff and it worked fine. The only problem is I had to filter it after mixing a 40% 2000ml solution (2000 ml hot water and 400grams POOL CHLORINE REDUCER SODIUM THIOSULFATE. An extra step but if it saves money to use this stuff, then I am all for it. I am not sure why there are white particles after mixing. A lower grade of chemical? Other reasons? Cost $380 CAD including shipping to my front door!
Note* 150lbs of fix should carry me for a while. Next year? 2 Years? When I start doing the 35x35 plates, I will require a ton of fixer.
