Green water ggrrrrrr......

[Patchtig]

for the first time ever I have got a green pond. It was crystal clear 3 weeks ago. I always leave my waterfall on.
My bio filter system never failed before.
I am going to buy a UV light for it now but unsure what is the best for me.
My pond is 4,500 gal ish, 6,000gph pump. Also what does the ionizer do?

Water lilies can have a huge effect in reducing green water.

My clear water had a green shade to it a 5 weeks ago
It does this every spring when the sun starts to warm the water
I treat it 1 time each spring with a half dose of algae fix , and I'm good to go for the year ... I don't run a u v light

Increased aeration and water movement will help reduce green water.

It sure is! I never have green water, but also have a ton of plants taking care of it.

Stay away from ionizers! https://www.gardenpondforum.com/articles/are-pond-ionizers-safe-you-be-the-judge.23/

Green water is a sign that your biofiltration is working. It is a normal occurrence in Northern latitude ponds. It is Nature's way of restarting the aquatic food chain and should disappear on its own as the zooplankton population gets re-established. During this time it is important to not overfeed your fish.
Spring algae blooms (green water) are a sign of a pond re-establishing its biological balance.

Are those bearded irises that grow from rhysomes? I did not know they could grow in water! Wow

Uv clarifier are a great tool but hold off til after the weather stabilizes. As the others said, green water this time of year is usual. 3 days ago I couldn't even see my fish and today the water is clear to the bottom.

I am not sure what kind of irises they are but they grow very well in my pond. They have purple flowers on them when they bloom.
