Tank cloudy over night!

[JackerVenom]

Just added 2 new corals yesterday and woke up this morning to cloudy water! I did my tests and noticed some parameters are off but I have never tested my tank before other than nitrates and ammonia.
Here’s my Parameters:
ammonia: Under 0.1
Nitrates: 5ppm
phosphates: 0.073
Alk: 6.7 dkh
Cal: 416ppm
Mag: 1300 ppm
pH: 7.2? Tested with hanna

I have some Red Sea ABC which I havnt used and I’ve never had issues with my tank other than my monti cap turning a little white in the middle. Probably due to low dkh? All my softies and lps are doing good. Pictures down below.
what should I do?

Is the cloudiness causing problems? Could it be as simple as a snail spawning? If so, that’s not typically a problem. If it persists it could a bacteria bloom. If it’s cloudy tomorrow, I would do a small water change and possibly add GAC. If it’s a bacterial bloom, UV will help.

Oh I never thought about the snails! Thanks! What is GAC? Sorry never heard that term?

Im pretty sure he is referring to activated carbon.

Yep. Granular Activated Carbon. Like ROX from BRS for example. As opposed to dosing a carbon source.

This happens frequently with the trochus snails in my reef and will clear up after 6-8 hours. Always happens overnight to I wake up to a “milky” looking tank. Take a very close look at the snails.

How many hours has it been cloudy?

I would also retest the pH to have a couple more data points.

I just added some trochus snails so that might have been it! Thanks!
