What are you measuring salinity with?

a refractometer

Just an FYI
1.023 is on the cusp of lethal to everything except your fish

Definately dial back your skimmer
Ideally your skimmate should be darkish, like regular to strong tea

Are you noticing any excessive salt creep in,around, behind anything?

I did have some salt showing up around my sump caused from splash out if my emergency drain. I have since extended the pipe an fixed that.

I will keep an eye on my values.

Any update ?

Where do you get this info from? 1.023 is lethal why? Most of the LFS that i've been to keep there salinity at 1.021 And also can you explain how skimming is removing salt out of the water? I had this discussion with another newbie on this site and his answer was that another member told him this. I could'nt find the thread until now. I have never experienced any such thing and I empty alot of skimate out per week with an evaporation of 10G of water per week as well. It's topped up with fresh water and no salt added. I'm looking forward to hearing a solution for when my skimmer starts to make my salinity drop so I can fix it.

Do you have to come across so strongly ?? :razz:
If I ever hear of a solution for skimmers and Sg, you'll be the first one I contact

I can't back it up ... I've read that a Sg of lower than 1.023 can be lethal to inverts. In my post


I didn't say it was lethal, but I did say it is on the cusp of becoming lethal. Is there something wrong with being safe ?

As far as the skimming goes, if the OP is skimming wet it only stands to reason that there is SW going into the collection cup

I've measured 1.015 in my own cup, so a loss over time makes sense if they are skimming too wet.
Plus, if the OP is cycling a new tank, and not performing WCs, it stands to reason there will be some Sg drop

OK, I'm done editing

Yea sorry bro. In just straight up and blunt and don't use smileys. I just can't see skimmers having an effect on salinity. I've never seen salt creep in skimmers. I'm no chemist but I can't see salt being drawn out if the water by the skimmer foam. IME I've never seen salinity drop, only rise. I was hoping you had somewhere that you could direct me so I could read up on it myself. Peace

Oops double post. Was tryin to edit spelling. Hate my iphone
