How fast can I change my salinity

[sirrealism]

So my refractometer broke a couple months ago so I have been using an old hydrometer. Today just for the hell of it I took it with me to the LFS to get a reading of how far off it was. It was reading 1.020 when the LFS refractometer was reading 1.025!!!!!!! So i purchased a new refractometer and checked all 6 of my tanks. All at 1.030 Dammmmm. So now the question is how fast can I bring the tanks back down to 1.025? I am amazed that I have not lost any fish or corals although some are not to happy.

I was told you can bring it down fast just not up....

really. thats strange If thats the case please let a couple other members chime in and agree. Thanks. That would be great. Really I just want to bring it down something like .001 per day. So tomorrow i want to get them down to 1.029 and sat 1.028 is that ok or to fast. i do have SPS and LPS in several tanks

.001 per day should be good, I would go a .001 difference every 2-3 days, keep an eye on your Ca/Alk/Mg as the levels will be different as you bring down your salinity

thanks Matt and Pedro.

Nothing good happens fast in this hobby. If corals are doing fine at higher salinity then I wouldn't drop it too fast. Obviously the slower u drop it the less stress you'll have on corals.

That holds more true towards fish I believe.
