Salinity question

[josh88997766]

I’m starting my first fowlr tank also my first ever saltwater and plan on keeping clownfish I have a 10g tank and am trying to get to 1.023 ish salinity how much should I add here where it’s at rn thank you

That is a hard question to answer, for me at least. I pre mix everything, so it is very straight forward at 1/2 cup per gallon of R/O water.

There's a really helpful online tool that I've used in the past here

Target Salinity Calculator

Aquarium calculator; Create a water-change schedule that can be used to reach a target salinity.

I would mix your salt very strong (using RODI water) in a container and add a bit at a time to you get what you want.

THIS! I put it in 5 gallon buckets with a power head.

You can lower salinity quickly without harming fish. To raise salinity you must do it slowly. No more than one or two points a day.
Would mix up some new saltwater and add it as top off until you get where you want

Do you know how much salt you have already put in? If so, I can tell you how to calculate exactly how much more you need to add.

Hello there.

So are you asking how to 31 or 1.023 during the mixing process or you are trying to adjust your water now at 26 to 31 ?

if you're mixing, there should be instructions ..
for me, i use redsea blue bucket and its 2.5 cups of salt into 5 gal of RO to get 1.026.
if you're not sure, add small amount of salt into RO, wait 15min ish and check.. repeat until you see the # that you want.

lastly, if you're asking on how to adjust your water from now a 26 to 31.
do small water changes of 31, maybe like 5% since its only a 10 gal. repeat water changes until you get whole system to 31. probably 3 time (?)

doing small increments will not shock the fish vs completely drain what you have and replace with 31 parts salt water.

hope im not making it more confusion. Good luck !

About 4 cups I just added a 1/4th cup so we’ll see

No it’s good thank you

4 cups got you to 26ppt

4/26 = 0.15 cups/ppt

You need 9ppt more so

9ppt * 0.15 cups/ppt = 1.38 cups.

subtract off the 1/4cup you just added, and I suspect you need about 1 and 1/8 cup more salt.

Thank you very much will try

Is that tester even accurate? I don't trust those swing arm plastic testers

Me either! I use a calibrated hydrometer!

 

[rhitee93]

The swing arms aren't mainstream these days, and wouldn't be my preferred solution. However, there are a lot of folks on here that use one. The most important thing is consistency.

That's all I used in the 90's Lol

IMO, that target is low, and new salt water made to the low level will be low in calcium and magnesium and most other ions.

Aim for 35 ppt (sg = 1.0264), the whole ocean average. :)
