Question on Salinity

[HKAVR45]

I've always run my tanks for the last 20 years at 1.025. No reason in particular other than maybe it was easier on the eyes to read the larger scale mark than the smaller. I know people maintain mixed reed tanks anywhere from 1.025 to 1.028 and 1.026 is the level of natural seawater.

So the question is would raising the salinity result in any noticeable changes? Or is the .001 - .003 margin of error negligible?

I'm not trying to "fix" any issue, just wondering how many reefers stick to a very strict salinity value.

Simple answer is no.
if its been working for you at 1.025, then there is not need to change as you will definitely not see a difference what's so ever.

Happy reefing

Interesting question. I thought you were going to ask about the other direction— like 1.04 or even 1.03. I have just some softies in a tank with fish, and I go about 1.03 (mainly for the fish), but the softies all live. However, it maybe not the best coral growth a reef tank owner would be looking for.

I run 1.0265 as I run close to NSW levels.
I have never had an issue if it goes up or down a little from 1.0265.
My range is 1.026-1.027.

20 years of stability! I would not change a thing.

My reef has always been 1.025 and have never had an issue. With 20 years of stability, I would just leave it be. 1.026 won't make a big difference.

I agree.

Thanks for the responses. Guess I should clarify. 20 years of running that salinity on several different tanks! Sorry left out a minor detail.

I try to bump my reef up to 1.026(with 1.027 weekly WC), but it always seems to settle on 1.025. Now whether thats from my ATO adding to much water cause my skimmer pulled to much or what, IDK. But I've never had an issue so I just leave it be.

I doubt you'd notice any difference.

Your tank decides for itself what salinity to use. Nice.

You should train it for other parameters too. lol
