Question Green Water

Hi, I'm new to the forum, but I thought this would be the best place to ask about my tank. Two weeks ago, I added a larger dose of phosphate to my tank because my plants had been getting great growth with what I had added so far. Unfortunately, I added too much and green water took hold of my tank. Since then, I have done around 5-6 50% water changes in my tank and reduced lighting to 5.5 hours per day, but I have not been able to remove the green water. It is bad enough that I cannot see the other end of my 4 foot tank if I stand to the right or left of it.
I would love any suggestions or comments anyone would have in regard to this problem. I appreciate any help!

Tank: 55 gallon, Finnex Planted LED 48" light, pressurized CO2
6 Rainbowfish, cories, loaches, 10 Rummynose Tetras

Thanks!

Complete blackout for 3-4 days and or UV sterilizer. When I say compete black out I mean not a sliver of light inside. Use black trash bags to ensure no light inside. Those are the two only reliable options out there I am aware of.

I got a UV light and it made a huge difference, cleared it up wonderfully. Since you understand what happened, you should be fine after a blackout or with a UV.

Thank you for the help!

What UV sterilizer did you purchase? I'm thinking about investing in one as well.

Just went through this on my 29g. My solutions since I didnt have a uv filter was a $3 pillow and an extra hob filter to with the pillow's filter media in it. Cleared up 100% in about 7-8 days
