I have a 32 bio cube— all my numbers where fairly good and holding- one week Kh from about 9-12, mg from 1400-1600, ca- 450-600, my salinity always between1.025-26, mix my own with Red Sea black , changed water on Sunday, about 25- came in monday 21, stopped dosing done my normal water changes, even used premix salt figuring would bring numbers down.. salinity steady1.025- Kh down to 10, mg still about 1600- ca about 500 , and like I said 5 gallon water changes every week- when numbers exploded all my coral started freaking most seem to be back.. was told it was the weird overnight salinity drop, any ideas for a long winded first conversation
