High salinity

Hi, I have a fish live rock tank and I am new to salt water tanks , but I had brother watching my house for a few weeks and he topped off the tank with salt water not knowing. My sg was 1.04. What can I do to lower this! None of my fish have died yet thank goodness.

The only thing you can do is pump some water out and replace with fresh water .
What size tank is it ?

+1 do PWCs with fresh RO water. Do it slowly over the course of a few days.

If you litterally mean 1.040 Salinity then I would immediately change 40-50% of your water and hope for the best. Hypersalinity is not good

I would absolutely suggest against this. You don't want to shock your live stock with a salinity change. Anything like this needs to be done slowly rather than all at once. It would be best if you could change out 1 gallon of water at a time with fresh water hourly until the salinity is back in check.

You can take the salinity down as quick as you please. No harmful effects come from lowering salinity quickly. When raising salinity you want to be careful . More than .001-.002 can dehydrate the fish .

The same as all parameters .
Most animals stress out easily with slight shifts .
I would lower it gradually just to be safe .
Again it's your tank , your stock this is how I would if it happened to me

I agree . Do it the way you feel comfortable doing it . I was just merely shedding some light on what really is an issue with salinity change . Going higher you need to go slow and that going lower quick will not harm the fish.
