Any update ?

Yeah, 1.023 doesn't sound correct. I have purposely lowered my sg by adding plenty of topoff water before vacation and measured less than that without any negative effects on my tank.

Hey Greg got your PM.

[lastlight]

your cup contains tank water in it plus organics. just because it's dirty water doesn't mean it's not salty. those bubbles pop and splatter salty water on the lid and it drips down. unless my logic is off i'm not sure how skimming couldn't to some very small degree affect salinity? and if you're removing a lot of salty skimmate you're lowering your sg.

plus this

Hmmm I recalibrated my refractor checked my tank salinity, it's 1.025. Skimate is 1.015 same as Greg's. I wait until my skimmer cup is full before I empty it. The sg never changes. I also measued how much my collection cup holds and it's 14 cups of liquid and not including the sludge. Thats quite a bit. So you'd really have to take a whole lot of wet skimate out to effect salinity that much. P:lus throw in the 10G of fresh water thats added. Have any of you brainiacs looked in to this theory at all bout skimate dropping sg?
