HI
I check my water at the store they said everything is fine just a water change will be good i did 10% water change all coral closing and same to anemone but my 3 fish died right after 3 hours water change
salinity 1.024
PH 84
temp 78

here is the video after 3 hours water change

Do a bigger water change.
Did you change or add something to your filter?

check your alk!

Agreed! Do a massive water change, as big as you can. Something is in your system that's causing your fish to die. Have you used any household cleaners near the tank lately?

its not just your fish everything in that tank is dying, corals are closed,fragplugs are bare and a clear nutrient problem happeneing.


honestly if you want some help your going to have to include equipment list, schedules, parameters(in full) and livestock....without its just a shot in the dark and my shot is no oxygen i see 3 powerheads none of which are breaking the surface....your green star polyp has no movement at all and all fish are hiding,its also something they dont test for at lfs. how long did you mix the salt for and how did you go about mixing it and adding it to your system??

plus if you dont keep your powerheads clean they lose alot of flow so they look like they are doing their job but if you put your hand in front of them theres not much;)

No i didnt

there is a pet store manger told me when i add tap water i should add kh into tap water all the time i bought a kh bottle from him

is it okay if i change 80% water ?

you need to check you alk (kh), your tap water is prob high in alk and if you added kh you are prob really high.
I would do 25% wc at a time so you don't cause too much shock.

Ok. So from what I read, you did a water change and the fish died & the corals are unhappy.

You better find out what is the problem with the water (probably too much kH if that's what you added this time) before you compound the problem by doing another big water change and adding to the issue, instead of solving it.

With tapwater, are you using Prime or what to treat for chlorine? Maybe the city added chloramine in the water system.

+1 on the chlorimine, if it is then you might need some amquel to get rid of the ammonia.

What's ALK ?
I'M going to do water change 30% and I'm adding prime

HUH??? That's a new one. No offense to those who my work at a "pet store". But that is where I have heard the most bad information given out to people. Go to a store that specializes in SW. You should NEVER add anything to your tank that you do not test for. Get yourself some test kits and try to learn to do your own testing. And don't let the stores try to sel you the Hagen Master Test Kits which are for sale at most "pet stores". And to answer your question on what's Kh without gettin into too much long winded detail, it's Alk. By the way the quotations are for the chain stores. Once again try a SW specialized store.

Alkalinity or carbonate hardness (kh)
Should be about 7 to 9 dkh.
the kh additive is raising your alk (kh)

couldnt have said it better:)
how can you know what to add if you dont test for it.:)

mohammad, you don't live too far from J&L aquatics. Take a water sample ( about a half liter ) and ask them to test your water for PH and Alkalinity. They'll tell you what's wrong with your water .

IMO, and just from watching the video, something must be way off. Please get a test kit for the basics and maybe copper too. Test the tank so you know where you are at and continue with water changes but test the new salt water as well. Could be anything causing the problem and you will find it if you keep looking. Bad salt, bad fresh water, low oxygen, high nutrients, heavy metals, etc.

Best of luck to you.

i took my water to 2 pet store they telling me diff things about my water
im confused , i dont wanna name the stores here .
one of em told me the KH is good and the other one said the kh is high

J&L has new rules for testing water on the weekends
if you want ur water to be tested
you have to know what do u want to be test so they only test one thing

the salinity show 1.024 at home
but at J&L said the salinity is 1.028

What are you using at home to test your salinity? What was the kH reading the stores got from your water?

Honestly, you need to buy some test kits and learn how to test for parameters. It is kind of an important part of keeping a healthy tank. Especially when you're just starting out.

i will buy a test kit when i can
at the store they said its just high everything
the water condition is like a new tank set up
im using a "redsea hydrometer " to check my salinity and temp "

How old is the tank?

9 months old and it was running before i bought it

Hydrometers are usually inaccurate. They tested salinity with a refractometer at J&L. 1.028 is quite high. Should aim for 1.024-1.026.

If you need one, I have a spare Brand New Refractometer I'm selling for $35. I knew a local reefer who completely wiped out her tank because her 4 hydrometers were all off and by the time she checked with my refractometer, her tank's salinity was 1.012 or brackish.

Ugh... that sucks. It's also a mistake I've made. I let my little guy play with the refractometer a few times and forgot to check calibration of it after. It was quite low, reading 1.019 when it should have been 1.026. Luckily everything was okay but I let it go on for far longer than I should have. Hopefully that's the worst mistake I make with this hobby...

here is couple pics of my water change

and i use this to check my salinity and temp

you need a refractometer, those hydrometers are junk

str8 up , it is junk ill get my refractometer soon :)

Hey folks
i bought this sea cucumber
is it normal with this cucumber ?

Hey folks
i bought this sea cucumber
is it normal with this cucumber ?
i had one before i sold it and i never seen this kinda before but i bought it from store like this

http://i1053.photobucket.com/albums/...732839-800.jpg

i dont understand if all your fish are dying why would you buy more stuff??

i bought this a day before my fish died

There's your problem it's releasing toxin, run carbon and remove it without stressing it out. Follow with a big water change and more carbon.if not when it dies i bet it nukes your tank

thats your guaramnteed issues your having right there, get it out and new water and carbon.

oh okay thanks can i return it to the store ?
i saw it in the tank at the store it was healthy , as soon as he tried to take him off the rock this kinda things came out of it
and i told him is it stressing out , he said " its just waste dont worry its normal "

isnt that illegal to sell stressed out livestock ?

no not illeagal but you need to research your purchases your lucky if this thing doesnt nuke your tank, they need very stabil conditions. your doing a water change may have stressed it out plus transit from the lfs.

a big lesson was learned here hopefully do your own research stores want your money, just google something before you buy it:) good luck

def return it to the store demand your money back for not warning you of what it can potentially do:)

i had one before , this one stressed out in the store tank i was watching him and i asked him if it is stressed out he said ( its the waste ................. )
