Algae in clean water tank

I have a clean water tank that holds 1000 liters I noticed a little green at the bottom. Pretty sure it would be algae. It would be hard to clean with small
Opening at top . Is there anything chemical I can add that will kill
Algae and not my plants ? Thank you

Keep it dark. Why 1000 liters in a tank, whats the water source?

Oxygenation. Aeration. Algae blooms in still water low on oxygen. Try that after thoroughly cleaning it up. Air pumps are noisy but necessary.

No need for airpump you can use a water pump with that buble thing.or make a waterfall.stagnant water is just an invite for bad bacteria

If you have room and the setting for a waterfall.

Pool shock ?

That’s 265 gallons, Ace. Ain’t no little thing eh? But liters just sound so small!

ONE: Always use a completely opaque water storage tank – Algae uses photosynthesis to reproduce – in simple terms, algae needs light to grow. So, if your water tank does not allow light in through the roof or side walls, algae cannot grow.

TWO: Add a quarter teaspoon of bleach to every gallon of water you store – Bleach kills algae and prevents it from growing. A common question is: will plain old household bleach remove algae from water? Household bleach will work fine for this.
Pro tip: We suggest you use bleach that is five point two five percent hypochlorite. Do not add both bleach and chlorine to your water. Use one or the other

THREE: Add four parts chlorine to every one million parts water – Chlorine also stops algae growth. In this small of a ratio, the water will still be safe to drink or irrigate with. The most important thing to remember is to follow the ratios of bleach and chlorine very closely.

“Does falling water create oxygen?



In general, a waterfall only aerates the surface of the water, down to approximately the depth the water penetrates when it falls, and oxygenated water likes to stay near the surface, which isn't sufficient on its own.”

I’ve got experience using a 500 gallon livestock tank raising crawfish. With the great help from the aquaculture folks at LSU. I was using a waterfall to oxygenate. Until it was obvious more was needed.

Light must be getting in or algae couldn't grow.

Pool shock and bleach are frequently used in growing.
