A drop in oxygen would be my best guess. Especially with a temp of 85-86f.

That is a true bummer I am so sorry

Tap Water TDS 165 is what stuck out to me immediately. Do you put any sort of dechlorinater in the water before mixing your salt? Even at that you would be putting a lot of bad water in your tank. If you dont use any kind of dechlorinater then thats what did you in. Fish and corals can't take chlorine and high amounts of other impurities.

Drop in oxygen at that high of temp and a combo of bad water. There's your answer.

So sorry? How close in time was the water change to the die off?

That is the first thing i thought of.. + maybe something else got in the water???

Maybe the anemone died first and killed everything else.


How long has this setup been running?

Same here the TDS is very high for a reef tank. How long has the tank been set up? Have you always used tap water in the tank? It is that or some other toxin has let loose but wow that is terrible that you lost everything.

 

[mameroo2000]

I have this setup for 6 months but I bought used from someone it was running for 8 years
I moved everything in the tank including the water .
I allows use tab water but I test the water for copper befor I use the tab water and allows 0
And never had problem with tab water that i know about so far.
The sand was crashed corals, i Change it to dry sand last week I moved all the water and the livestock to empty 50 gallons tank

Yes i do use dechlorinater for the tab water .
If the oxygen is my problem how can I solve this problem and how can I test
My oxygen

 

[Kyle10181]

oxygen wise, you are looking to get higher surface movement to pull the air below with your power heads. Do they move the water enough to break the waters surface? If not, you should strongly consider repositioning them so they do so, and this will improve oxygen levels.

 

[mameroo2000]

Thanks for all input
Ill take water sample to my LFS and ask them to test oxygen level in my water.
I think high temperature and low oxygen killed all my livestock .
I do have 4 hydro powerhead 2 1050gph and 2 240gph all 4 powerhead are connected on hydro wavmaker controller , do I need to add more powerhead to increase my oxygen level or add airline with Wood-stone ?

Your skimmer already is putting oxygen into the water. I think it's more of a issue with tap water or something else. Isn't your pipes copper?

 

[mameroo2000]

I'm not sure what material my pipes but I knew there is no copper In my tap water.
I'm not sure what is the problem could be oxygen or other poison in my tab water or one of my livestock died first and kill all my tank or changing my sand from crush corals to arguanic Sand .
On Monday ill take water sample to LFS and test my water
And test my oxygen level

 

[mameroo2000]

I Ben told from a friend that is my skimmer to small for 90g
It's rated for up to 65g ? Is this cold be the problem ?
Befor I used this supper skimmer 65g with Red Sea skimmer 40g ,
but my Red Sea skimmer pump died on me last week so for the last week I Ben use only coralife supper skimmer 65g
I really don't know what is the problem.
But I know I'll buy RO/DI system on Monday

 

[scuzy]

The ratings to my understanding is how well it can skim doesn't mean that it can be use for a larger tank if you bio load is very small. Correct me if I am wrong anyone?

 

[mameroo2000]

I find out what is my problem with my aquarium after lab test
1- high temp and low oxygen
2- my light to strong for my anemone and some of my corals
3- I do have low amount chlorine in my water due to
fill up my ATO tank with tap water without using dechlorine
4- changing my sand bed from crashed coral to sand quickly , cost shock to my system
I learned my lessen in hard way

I doubt there any standards for skimmer "ratings"; they are simply the mfg's suggestion for maximum tank size. In other words, ratings mean about nothing. they're just a very subjective suggestion. I doubt you could really determine ''how well they skim''; way too many variables.

i agree with you
It's all about money grab

im going to go with temp and tap water.

chlorine will kill alot, and 86 degree water is enough to kill a fish if the oxygen is even slightly low.

You should be at 78-79 degrees, and using only RODI water.
