How are you measuring salinity?

Hydrometer

Hydrometer

always always make sure you have calibration fluid to check against I have two and sometimes get different numbers and I know one of them is off sometimes both hahahah

For a hydrometer? Or for a refractometer?

What style hydrometer do you use?
Probe, refractometer, floating

It’s a floater made by tropic Marin. As long as the water is 77 degrees fairly accurate compared to ICP testing..

That's the good one, can rule that out.

Love this thing.

oh sorry I meant for a refractometer, don't mind me

What are your testing results specifically?

Maybe run some carbon if you can.

Dumb question… what does running carbon mean??

Running carbon as a form of filtration.

 

[sharkbait]

Thanks. I see OP said water parameters appear in order, what filtration benefit would the carbon add in this context?

There are lots of things we can't test for. Especially some of the biologically produced coral toxins that they use to fight each other. Carbon helps remove those and other things you likely don't want in the water. Softies seem to be especially vigorous in producing these.

Never know carbon help with coral produced toxins..good to know that..

The reference to the benefit of carbon is exactly the reason why it is a very good idea to run (good) carbon at all times (just far less is needed than what sellers typically recommend).

Can it also strip out trace elements?

Yes, this is the downside I mentioned in a couple of posts earlier in this thread. Nothing in reefing is free unfortunately, but awareness of the downside and stating this when recommending an approach is my preference.

Was listening to an old Jake Adams video where he said that he kept his after his filter roller to reduce the amount of gunk that got into his to maximize its life. Whether that does anything or not, it seemed like sound logic. I usually kept mine after my skimmer.

It can

Trace elements can be replenished with water changes, dosing, and it's present in fish food

Absolutely. After the skimmer is the ideal location (tricky to do in my nano sump though). Unfortunately, the skimmer also reduces trace elements quite a bit.
