tank crash?
 

I'm in need of some advice.i did my weekly water change yesterday and cleaned my skimmer and whatnot,dose Zeovit additives and that was it.when i checked the tank this morning,the water is cloudy and my corals look calcified,and they seem to be covered in sand.im dumbfounded by this:cry: i dipped what frags i could dip in coral revive in hopes that it'll help.

What did you dose?

Anything that can spawn snails clam etc?

i have astrea snails...i dosed KZ amino acid,pohl's extra,macro elements and iron.it's just my acros and montis that are affected,my acans are perfectly fine.

Can you post your water test numbers, or a picture?

My water parameters are

N03 5 ppm
P04 0
Ammonia 0
Salinity 1.025
Ph 8.2
Cal 420
I haven't tested for alk and mag yet but will do after supper.

The water doesn't look cloudy now so it must have cleared up a bit?
If the corals are suffering, I would do another water change now without any additives until this gets figured out.

I couldn't find a tank journal for you. Can you tell us about your setup?

Hey Mitch.i just did a 4 gallon water change today,it's starting to clear up a little.i have a 33 gallon tank with no sump and with HOB skimmer and refugium.i have about 25 lbs of live rock and a 2" sandbed.i currently have four fish,five astrea snail,brittle stars and an army of collonista snails.
