how much salt

[driver3260]

My salt mesurement is 1021-1022, so i need to raise it, but do i need to add more salt or have i got too much?

Why do you need to raise it? Anywhere from 1.020-1.026 is an acceptable range, unless you're raising particularly sensitive organisms (and if you're posting in this forum you probably shouldn't be doing that just yet).

If you do decide you must raise it, mix it into some tankwater first, ensuring it's fully dissolved, add a little bit at a time and retest until you find the right amount. Doing it any other way requires utilizing mathematical skills that don't come to me very easily. :lol:

The way I'd do it is to make up water for your water change at a higher salinity than your tank water. If you're changing 25% of the water and your target is 1.025, with your current salinity, I might be tempted to try making up the water for the change at 1.027 and see where that gets you. It might not hit your target, but you'll be a bit closer. Then you could do the same with the following water change if you still needed to raise it.

Bear in mind that this is very much a rule of thumb method and there is probably a way you could work out exactly what salinity of water you'd need for a water change to raise it to a certain level. Trouble is I'm no mathematician and this works anyhow. :wink:

To raise it you need to add more salt.

how much depends on how much to raise it and how big your tank is.

For clarification, do not EVER add salt directly to the tank. Mix a higher s.g. water your next water change like the good Ape says. Do it in multiple steps to avoid osmotic shock to your tank's animals.

osmotic...

nice

You can let natural evaporation elevate the salinity and then top off with saltwater that's equal in salinity.

Simple safe and effective. This methods works very well with small tanks or tanks with decent sized sumps.

You can even top off off with same salt water for several days to weeks to slowly raise the salinity and then do water change at your new salinity with no issues.

That method too is very safe slow and reliable and should never result in any osmotic stress on the fish or animals since the water you are adding is within .001-.002 of that already in the tank.

Here is a formula you can use. Lets say you are going to do a 25% water change and you want your salinity to be 1.026 from your 1.021.

(1.026 - (1.021x.75))/.25= Salinity of make up water or 1.041 in this case.

I would make up salt water for the wc at the target SG or slightly higher and make the adjustments over a few weeks.
