Hello everyone,

I am currently trying to raise my salinity from 31 ppt to 35 ppt in my 20 gallon and I’ve been doing daily top offs with 35 ppt daily and doing water changes at the correct salinity to try and fix my salinity levels, however this time I accidentally mixed my top off water to 40 ppt, would you consider that fine to top off with?should I bring down the salinity for my top off water to 35 ppt? I’ve also not been doing top offs the last couple days just trying to decrease salinity so I need to replace about an inch of water.

This is the inch of water that needs to be topped off, I usually fill to where I can’t see the water line, I’ve also been able to increase my tanks salinity by 1 ppt over the last week by topping off with 35 ppt so now it’s at 32 ppt.

sorry im a bit confused. so youre topping off with saltwater?
Topping off with saltwater in order to raise salinity to 35 ppt, because my salinity is at 32 ppt, I accidentally mixed my saltwater that I was going to use to top off to 40 ppt, I was wondering if that was okay to use since it’s a bit higher than normal.

That would be fine to use. to get you back up to 35ppt.
You can use a calculator to calculate how much it is going to take.

Yeah just I would pour half in give it around 30 minutes and then pour in the other half if you want to be extra safe. Also make sure to pour in the back compartment and not directly on inhabitants. Let’s say it’s a gallon of water and system with rock and sand taking up space is 17 gallons total (of water) it will only bring salinity up to 32.5 from 32 so not a large swing. Evaporation will affect it. I always say though to just split it up if you can. You don’t want to make large changes instantly.

Why not just add a bit of water to bring it down to 35ppt???

This is going to take forever to get back up🙃 I have no clue how my clownfish survived me dumping in that low of salinity water for weeks.

Drops in salinity are easier to handle than raises, and fish can handle lower salinity just fine. Many stores keep salinity low to inhibit disease.

It’s actually not that low at all. I like using Specific gravity readings since it’s easier for me.

The ocean salinity is naturally 35ppt or 1.026 sg. Corals can survive and thrive usually between 1.024-1.026 sg. 32ppt is actually 1.024. A lot of fish breeders and shops keep their fish at 1.020 or sometimes even less.

I keep most of my tanks at 1.025 with auto top offs and 1.024 without them for my office tank 1.024 = 31.8ppt so you actually do not have to do anything really. Do you have an auto top off? If not I would actually say to stick at that number in case you do not top it off in time since if you reach 1.027sg or 35.8ppt that is more likely to kill your fish and corals than 1.024 or 1.025 or 31.8+

Also like I said stores keep fish at 1.020 a lot of the time which is 26.5ppt.

Yeah, I just wanted to bring it up to the 1025 range because I have an anenomne that’s been ticked off lately, and I plan on getting some harder corals, so I wanted to lock everything else in before I added other stuff.
