Are you saying your fish are in 1.023 water and you want to get them back up to 1.025? I don't understand what is being asked. Are you adding new fish? If your fish are already in 1.023 that's not a big deal. Just top off with saltwater instead of fresh for the next couple days to get it back to 1.025.

Jk I see you're doing a water change via lfs rodi water. Got it haha wow I was confused. That won't lower your water enough to really bother the fish.

That'll show me to try to post and work at the same time. I think everything is fine with what you were posting about. Salinity can fluctuate in small amounts without issues as long it stays in an acceptable range. Don't go above 28 and stay above 24. I personally keep my tank at 1.026-1.027, more because it always seems to measure out to that without adding more water...but I hope you get the idea at this point.

I personally wouldn't trust lfs water. You need to get some of their straight rodi water and test it for tds, most never change the filters when they should, you lose control of 90% of you reef without yr own water

The built in meter are not very accurate, most don't have temperature condensation in them, a hand held is much better
