Cloudy water

[NemHost]

I started a new tank about four weeks ago. Tank is a 20g AIO system. There are two media baskets which have filter floss, marine pure balls and chemipure. Marinepure had been in my main tank for 4 weeks prior to being placed in this tank. Light is a radion. System was running without a skimmer until few days ago. There are a few zoa frags in tank and only one fish.
My issue is that the water started to get very cloudy about 7 days ago to the point that I can’t see more than a few inches into the tank.
I performed a 35 percent water change four days ago.
I hooked up a aquamaxx hob skimmer on Sunday and water is clearing up slowly. The color of skimmate is bright green. The water also has a green tint. This leads me to believe that cloudiness is caused by algae and not a bacterial bloom.
I do have a uv sterilizer available but would rather avoid using it since I’m afraid it would be difficult to setup on this system and could leak.
Any suggestions on how to clear this up?
Thanks in advance

Are there any rock or sand in it? Hard to tell from the pictures?

No rocks or sand but there are about 25 marine pure balls

I guess best course of action is to put a uv sterilizer but I’m trying to avoid it as it would very messy to use with the location and set up of this tank.

I had the EXACT same issue and just as bad as yours. It's phytoplankyton - check out my thread.

Thr problem when it gets to that point is that there is constant die-off and that creates more nutrients which causes more phyto and your stuck in ever diminishing circles. Water changes won't help because it reproduces quicker than you can make RODI.

UV steriliser all but cleared it up in a week. Just a cheap 18 watt job.

Thanks for your reply. I guess I’ll be using the uv sterilizer after all. Really was hoping to avoid it but I kinda figured I had to.

I used a UV on mine - it worked, even though significantly undersized.

Your other option might be to add a significant number of clams . . .

My LFS had a couple of large homely unwanted clams and we discussed this very option. [emoji23]
