We have several 250 gallon water tanks on our homestead as well as two 1500 gallon tanks; each one is painted black. The reason is really quite simple. If you deprive the water of sunlight, the water will not turn green with algae.
Taking algae as a vitamin supplement may be beneficial, but algae in your water is not a good thing. As the algae grows in a water tank, oxygen in the water increases until a critical mass is reached. Then oxygen and nutrient levels begin to decrease. At that point the algae beings to die and the water will putrefy, making it unusable.
The 250 gallon tanks we buy usually have had soap or chlorine in them, so we take a trip to the local car wash to flush them out. We never use tanks that have had any type of petro-chemical in them. The first thing we do is to spray paint the tank black. My grandson likes helping with the painting. Rust-oleum makes a spray paint that will bond to plastic. FYI: It takes 5 ½ cans for one 250 gallon tank.
