Rower Tank Water Tablets 2 pack of 4 tablets - 8 tablets total (up to 4 year supply)167mg Troclosene (each tablet) Most rowing machines that use water resistance recommend using a purification tablet every 3-6 months to clean the tank. Instructions: Put one tablet in your water tank every 3-6 months Tips: Make sure the water you have in your tank is not hard water. Using bottled water instead of city tap water can be a better option for keeping the water clean. If the tank is currently dirty, you may want to rinse/flush it out with some rubbing alcohol and then fill it with clean water. Please note that simply adding a purification tablet to water that is already cloudy will not help clear up the water.
