Reef Tank is Suddenly Cloudy with Unhappy Coral

[Rjukan]

Yikes, 15 fish in a 75g that's only 6mo old?

With all of those fish, plus the inverts, plus the corals, I feel like you're really pushing the limits for that size tank. Definitely run carbon and hopefully things will clear up for you.

How much to do you feed, and did you notice the cloudiness happen soon after a feeding? Just wondering if the bacteria population can keep up with the heavy bioload, especially after a feeding.

Does anyone know what this frag is? This is an old photo. It is not happy as well with this situation.

I feed twice a day and try very hard to make sure it is all eaten.

I have recently increased my alkalinity from about 8.5 to 10.

How long ago did you increase this? And how fast did you do the increase?

2 days ago and I went from 9 to 10 by using Seachem Reef Builder

looks like a Duncan coral

That's the other coral that is not happy with this situation.

And your alk and calcium have been stable? I doubt it's a precipitation event that much later though.

 

[Scott Christenson]

Yes on stability

Oh and just an FYI, you might want to think about getting rid of that domino damsel before she gets too big. That fish can be super aggressive.

Thank you for the advice, this is what I need. I LOVE this forum, glad I found it!!

Bacteria bloom or something spawning is what comes to my mind.

Do you have a pic you can post? Curious to see just how cloudy this is.

Bacteria bloom can also strip oxygen from the water if it's bad enough.

Spawns usually clear up in a day or 2.

Looks like that one stressed coral is upsetting a few things. I wonder if that coral isn't the source of the cloudiness?

I think your tank looks nice besides that issue.

One last thing,

Run some carbon and keep an eye on things. Report back if they look worse.

That toadstool could be shedding. I've never kept one so can't really verify that. Also not sure if that could make the tank cloudy.

If your alk is at 10, and your calcium is under 400. Your macro ratio is off. You also need to know your magnesium. I’d run carbon, do a WC, make sure your calcium is over 420 if your alk is at 10. Get salifert mag test kit and keep your mag around 1350.
And welcome to reef2reef!

Also check your Neotherm. They explode. Make sure it isn’t cracked and causing a corrosion issue or something. I’ve seen lots of horror stories on here with the 150w Neotherm specifically.

Magnesium is only 1050
