Worried about livestock

[anotherfish]

Past 2 days my tank hasn't been looking the best. My hammers (2 different ones) haven't been opening all the way 50% of my zoas are half open. Couple important things to note.

I've had a bit of an algae bloom ( brown, possibly cyno+diatom but it's not overtaking the tank)
I got a new rbta and he wasn't looking so good last I saw him before he hid. Shrunken. I fed him and he perked up a little. Haven't been able to find him.
I did a 15 gal waterchange (about 30% 55gal tank, 30 gal sump) it didn't seem to help.

Testing from last night :
Salinity 1.022-1.026 reading from 2 hydrometer
Temp: 75-78 readings from the same two hydrometer
Ph 8.4
Nitrate 0
Nitrite 0
Phos 0
Ammonia 0
Alk 6 dkh (I added sodium bicarbonate to bring it up one point)
Calcium 440
No mag test

What should I do? Disassemble the tank and pull out the nem or maybe the nutrients are the problem?

Thanks in advance.

Knowing what the salinity is would be an important start, there is a huge difference between 1.022 and 1.026, the former would be very bad for corals, the later perfect. I would invest in a refractomter and calibration fluid since the salinity could well be the source of your problems. Running carbon would likely help at this point, but you need to know where your salinity is at.

Exactly this. Keep up water changes. Make sure you match salinity and temperature. You need to keep that temp more stable too.

- whats your source for water? How much flow is in the tank? What lighting and schedule are you running?

Most important thing right now though is correcting your salinity.

I've been planning on picking one up. I would like to say my levels are at 1.026 and 78, as that's the one I've always used t ok measure without any issues. The second one came in a box of free stuff I just got and has me second guessing.. whatever one is right, they are both stable.

My water is ro/di from lfs. The water change I did last night was seawater (from Scripps in san diego, not a bucket from the beach, it's very popular to use here in the reefing community and everyone has success with it)

Lights are led run blue 35% 1-12 and 10k 25% 2-11. Never had a problem untill now.

I'm running carbon in my filter sock

Thanks. I'll cut the lights down and check. If I turned off the lights would my skimmer work better?

Here's some pictures if they help

This what they usually look like

This is now

The whole tank

And a little closer

That last post was for another forum... damn tapatalk. Lol

Got a refractometer and salinity was 1.027-1.028 :O

I'll get it dialed in in the morning hope it fixed my issue!
