What's causing this cloudyness?

[nopenotpeter]

Over my last 2 water changes, I've noticed that I'm having a lot of cloudiness in my tank water. I've attached a picture for reference. I've not had this problem before, or if I did it cleared up after 24 hours. I did a ~40% water change last Wednesday, which it's now Sunday and it's not gotten better. I decided to check my parameters today and nothing to me is really standing out significantly but maybe I'm missing something. The only thing that's difference is I switched from red sea salt to Frittz reef pro mix (blue box).

Tank Details
Aqueon 29gal tank
HOB Seachem filter
Noopsyche K7v3 light

Params
Salinity: 1.025
Ammonia: 0
Nitrite: 0
Nitrate: 1.3
Alkalinity: 8.4
Phosphate: 0.03
Calcium: 455

I don't have a magnesium tester, so that's one thing I can't check.

Can you think of anything that's causing this that hasn't dissipated after 24-48 hours?

Thanks in advance everyone!

Might be a bacterial bloom. Uv will clear it if so

So I was having some issues getting my nitrates and phosphates back after I had to pull out my fish to treat them for ick. They were out of the tank for about 90 days, and I had turned off my protein skimmer after I put them back in in an attempt to try to let those numbers build back up to a manageable level as I was starting to see some dinos. I've gotten those fixed and decided to turn my protein skimmer back on.. I wonder if that did it. The skimmer has been off for about a month and I don't think I cleaned out the water reservoir as it's a HOB skimmer.

Sadly I don't have a UV light. Will it just go down with regular water changes then?

No water changes only enhances the problem. They reproduce faster than you can get rid of them.

Some activated carbon will help in the mean time

That makes sense - I'm not sure what I did to get rid of the dinos - but they're gone now.

Okay awesome - that's actually something I have on hand. I'll give that a try!

Thanks so much everyone!

Ignore the salt water on the glass - but I ordered a HOB filter with a UV light, and after 3 days it looks like this! That mixed with a yellow headed goby, all my algae is gone on my sand, and my tank is cleared up.

Thank you so much for your recommendations!
