I have three tanks - 55 gallon, 29 gallon, and 15 gallon. I'm going through quite a bit of water conditioner and was wondering if anyone had any suggestions for a water conditioner sold in bulk? I've been looking around, only seen one product on Wal-Mart.com but wanted to see if anyone knew of something better.
I use safe for my 600 gallons of freshwater.
This is what is in the link from hensleyjk(wow!); Sodium Thiosulfate
For most prime is good enough and stays fresh longer then other products.
