Water purification for 250 gallon rain catchment tank
We have a community garden in our park and we built late last summer a rain catchment shed that we are going to use to fill a 250 gallon tank. With the rain water that we did catch, we did have some algae start to grow in the tank. What can we use or purchase to purify the water to be able to water our gardens? Any suggestions would be great.

Best long term answer is to cover the tank to keep light out. No light equals no algae.
