How do I stop my outside water tank going green .i keep jetwashing it out about once a month

[P @ F]

Empty it , bleach it , rinse it , cover it with something that does not let light through , just about all you can do !

Black plastic Pallett wrap.

Green algae cant grow/survive without light.

Or invest in a black ibc tank instead.
Thats what i did, as i knew mine would be outside.

Someone painted theirs with black paint leaving a narrow stripe so they could see the level in the tank without having to unscrew the lid every time.

Was it Shrek and was the stripe horizontal? 😂

Before I put my IBC in a shed I put 2" insulation round it and over it and gaffer taped it.

Love the old gaffer tape!.
