Lil concerned

[Reef Swimmer]

I'm mixing water for a water change tomorrow and one bucket is 1.025 one is 1.024 and the other is 1.028. I've been chasing my salinity all week trying to get it up from 1.020 and I'm hoping this helps. My worries is that with 2 of them a lil off will it affect things a whole lot and will my dts salinity be off again. I'm using my circulation pump from my dt to mix the water.

Your tanks salinity can be solved like an algebra problem, so the four different values don't matter, per se, in the end. I posted some formulas I had worked out awhile ago here:

that should help you solve for how much of a change you need to do with the water you've mixed to raise the salinity in your DT

David not sure what size tank you are trying to bring up the salinity, but there is no hurry. You can bring it up slowly by your water changes or just top off with saltwater versus fresh.

Tank is a 90

Couple of questions/points:

1) What are you measuring with? I don't trust anything but a floating hydrometer. No swing arms, no refractometers (I have and use one).

2) It doesn't make much difference. Seriously, when it rains the reef salinity changes a LOT. As long as it's consistent, and within reasonable parameters.
