Tooooo salty. Will it be ok until tomorrow?

My tank was at 1.026. I have a 110g system. I did a 35gal water change. My tank is now at 1.030. It must have been pretty damn salty to raise the salinity that much through a 33% water change. I have fish, inverts, corals, anemones. I got the water from a reputable store, however I was the last customer of the day and the sucked the water out of the bottom of the barrel. I used to check the water every time but have grown to trust them.

The water was changed at 9pm. The store opens tomorrow at noon so I can get some ro/di water. So will my tank be ok for 16 hours at this salinity?

Phew. That's an abrupt change n some serious salinity. Odds are things will survive however its not good for anything. R u sure ur refracto is calibrated correct? What do u test salinity with?

........what, me worry?

It should be alright but some corals might not like it, you can remove a few gallons and add RO or distiller water if it's an emergency.

I hate to.agree here but I gotta! :D

I already dumped whatever good clean fresh water in that I had. I use a refractometer and I calibrated it five times with the supplied calibration water

Hit a Kroger. It'd make me nervous with my tank.

I'd probably try to get it down a smidge tonight. Just don't try to get it back to normal in one big move like you got it up though. Minimize shock as best you can.

Great advice al.

I am under the impression that fish can handle a rapid decrease in salinity better than a rapid increase. This is often done for hyposalinity treatments - some people suggest that you can drop the salinity a LOT and the fish do fine. But raising it rapidly is extremely stressful because it creates a lot more stress on their internal organs, etc. I don't know about the corals, though - whether they would tolerate a rapid drop back to 1.026.

Just because a fish can survive a quick drop doesn't mean it still doesn't severely stress them. In addition to the major stress already created with the rapid increase in sg. Plus a wide swing like this compounds the problem. They didnt just go from 1.030 to 1.026. They went 1.026 to 1.030 then back to 1.026. That's worse.

Also, in a hypo treatment, the sg can be dropped quickly only to save the fish a death from ich. In other words a life or death moment decision. It still isn't preferred to make any major changes quickly in our tanks.

+1 i would grab some distilled water and drop it to no more then 1.028 seeing as your fish are probably stressed enough as it is.
