Help with tank

[Pulsing Xenia]

Snails all dying off, all hermits and ceith snails are fine. Diamond goby is good, fish are all good. Emerald crab is fine and eating.
Corals shriveled up, a little stressed, they open, just not fully. Color is a little off.

Tank parameters
Ph 8.2
Ammonia 0
Nitrite 0
Nitrate 0
Phosphate 0
Alk 10.2
Calc 380
Mag 1400
Temp 75.6
75gal with 30gal Sump. Sump is running a filter sock, refuigium with live rock and chaeto.

Cant figure out what's causing the stress for snails to die and my corals stressing.

Any help would be greatly appreciated!

I'm not sure what's causing the snail die off, but what's your SG at and how do you measure it?

Do you use RO/DI water?

As far as your corals are concerned, your calcium is a little low. N03 and P04 need to be up a little. N03 around 5-10 ppm and P04 around .02 or trace.
The corals need some nutrients to be healthy and color up.

Also what lighting are you using? And what are you using for flow?

Sg is 1.026
Im running two ai prime hd's
I use Rodi water, tds is always 0
I use a refractometer to measure my SG

Could you have a bristle worm? I hear they love snails. Pull out the flashlight at night and see.

How would you recommend raising the NO3 and PO4? Naturally? Feeding more? I was under the impression it was nutrients deprived.

 

[Flippers4pups]

Are you dosing anything? Any changes lately?

Already checked. Doesn't look like bristle worms. They seem very slow, unstick from glass stay in place for days then die

No dosing at all, regular water changes every week

Feeding more can help. Skipping a water change or two may help as well. Turn your skimmer off for a few hours each day for a couple days too. Or dose potassium nitrate to get up your N03.

Bristle worms shouldn't go after healthy snails. They are more detritus eaters than healthy flesh eaters. Dead snail, yes they may eat the decaying flesh.

I agree @1WildBill about going hunting with a red light after lights out to see if you have a crab or eunicid worm in your tank.

Do a water change with a salt that matches your tanks parameters and monitor your tanks response. Also get an icp test (triton or ati) to rule out a contaminant.

Just turned the skimmer off for the night. I honestly thought I was already over feeding my 6 clowns, lol they never stop eating. I'll try the no water change and see what happens. Could it be the chaeto taking up the PO4? It was a decent ball when I tossed it in the sump. To big maybe?

Yes, it's pulling nutrients. Too big? Don't know.

The bigger it is, they would require more PO4?

Already tried. Same outcome. I'm leaning towards testing for contamination

What are your prime settings at? How long have the coral been in the tank?

Prior to the situation it was on standard 60% but I thought it was the light settings, so I changed to the attached settings.

I'm really confused I think its either nutrient deprived or a contaminate. I wash my filter socks in water in the washer, and rinse in Ro water, could the washer had bleach in it and contaminated the socks? If I recall, when I added a clean sock my skimmer went nuts. Maybe I'm leaning towards that. As of that moment, I did a large water change.

Your light settings are very similar to mine but I run higher nutrients. No3 at around 5 and Po4 around .07. If your nutrients are as low as you think the lighting intensity is probably to high. Generally speaking you can run higher intensity lighting with a higher nutrient load. If you want to get your No3 up you can dose potassium nitrate and if you want to raise your P04 you can dose Seachem Flourish Phosphate. Whatever you do raise levels very slowly over a month to help maintain stability of the system.
