Angelfish got sick after water change?

[jjk_reef00]

Specially Salinity saltmix even after mixing it for 24 hours has very murky appearience.

Please, any input would be appreciated.

Thank you.

Sorry for the losses. At what point does your salt mix become not cloudy (48 hours, more)?

How are you mixing the water?

I recommend the following:
1.) Make sure your mixing container is full of RODI before you add the salt.If you pour the salt into your mixing container before the water you will have problems.

2.) Add half the salt first and let that mix for a while, then add some more. It is a possibility that adding all the salt at once is causing some temporary cloudiness.

3.) Use a strong powerhead to aggressively mix the water. A weak powerhead will let the salt settle on the bottom and that may be causing problems.

A water change should not kill your fish, I would call seachem and tell them what happened. They may request a sample of your salt.

Thank you, jjk_reef00.
I don't think there is anything wrong with the salt. I used the same batch changing water in DT in QT without any problems. The only difference I did a larger WC than before.

Is 900 GPH powerhead strong enough to mix salt in tall 20g fish tank iver 24 hours? Maybe my 900 GPH powerhead is not pushing water sufficiently anymore. I don't see any salt left on the bottom of the mixing aquarium, but there obviously some particles in the water column since it doesn't look clear.

It cleares out over night in 180g DT with 10% WC.

Let's say it wasn't mixed well enough what could couse stress in fish? Also it was the last a few cups on the bottom if bucket.

Thank you everyone. I just want to make sure I don't kill more fish.

If it clears overnight it is likley being diluted by the large water volume in your DT.
I cannot say if the pump is strong enough or not, but I would definitly try adding 1/2 the amount of salt to a full batch of water and then mix that until it becomes not cloudy. Then add some more salt. If that works then you know you are adding too much salt at once with too little mixing power.

When I mix water in my 55 gallon drum I add 1/2-3/4 the total amount of salt to the full 50 gallons of RODI, then add the rest of the salt later because it mixes much better. In AZ we have hard water that sometimes precipitates and leaves residue in my mixing bucket. I've signifiangly reduced the residue since I started adding smaller amounts of salt to the full portion of water.

The next time, after I recover this loss, I'll do WC no more than 10%. Better 5% a few times a week. And that what I had been doing for the first 6 weeks.

To be honest, I would not lower the water change amount/schedule. If you suspect the new water, change the salt and/or mixing. I change 10g in a 15g every few days (depending on how many fish I have in there) with no ill effects. Keeping water quality high in a QT is mandatory, IMO.

Thank you, Ed.

I am going to start adding salt in portions.

Hmmm. Perhaps WC was just a coincidence.
I've been gone for 4 days. I've just checked and the water is very milky in QT.

Do foam filters get old? Do they need to be replaced? I've had that QT for 12 months.

Thank you.
