This tank contains the water for my outdoor irrigation system for hanging plants. It keeps growing algae, what can I do to safely(without killing plants) stop the algae build up in this water tank?

5 drops of bleach per gallon of water

This. A tiny bit of bleach should do it, and it’s not really any more chlorine than you have in regular tap water.

UV sterilizing light, might need to switch to a UV resistant container though

clear tank = photosynthesis for algae
keep it dark add H2O2 and change the water more often

Keep it dark, as in completely and perfectly dark. It works for hydroponics reservoirs so it should for you
