Use natural sea water to help corals open up?

[Patrick]

Need advice from bros. my button polyps and GSP do not open fully only some are opened. I was told change a quarter of water to NSW will help them to open up. What do you think?

Most likely the coral not opening up is due to water quality issues. You can try doing water change with nsw or salt mix and should be just fine.<br /><br />Sent from my GT-I9300 using Tapatalk 2

Doesn't matter whether water is NSW or salt mix. What's important is the water quality/ parameters. NSW can also go stale or come with pathogens.

I think so too. Will watch a few days and change some salt mix first. Thanks!
