hmm that's interesting. I have never heard that. I wonder if it actually rains enough to have any impact on SG though?<a href=showthread.php?s=&postid=14581648#post14581648 target=_blank>Originally posted</a> by aerius007
The arguement I heard towards the freshwater dip is that during low tide it will of course rain from time to time and this doesnt kill corals. I'm not saying one way is better or not, just that is what I heard.
