    Can Altosid briquets be used in an abandoned tank that contains only rain water?
    I have an abandoned tank that will be demolished at some point in the future, but for now I have to deal with it filling with rain water. This is a concrete tank and I have to keep it full to prevent it from floating out of the ground due to high water table. Since I keep it over half full, with approximately 400,000 gallons of rain water in it, I don't want to start a mosquito farm, so I want to treat with Altosid. How many of the briquets would be needed to treat 400,000 gallons of water that is approximately 6 - 7 feet deep? Would Altosid in another form (granular, liquid) be better than the briquets?

    The Altosid 30-Day Briquets would be appropriate for your needs.  The manufacturer recommends that you use 1 briquet for every 75 sq ft every 30 days.
