So I am trying to pinpoint what’s going on with my SPS frags. Experienced reefer that recently (6mo ago) upgraded to a larger tank and decided to add SPS - previous tanks was primarily LPS and Zoas. I have purchased several SPS frags from varying places and they look great for a few days and then within a couple of weeks they basically bleach the skin melts off and they die. I have no idea what’s causing this as I test my water regularly and do weekly or bi-weekly water changes (DT is Waterbox 130.4, ~100g display and ~20g sump) I typically do a 20-25g water change. I tested my water yesterday and here is what my got:
Alk 7.8
Calcium 440
Mag 1320
Ph 8-8.2 (Apex)
Salinity 1.023
I am at a loss and confused as all the parameters look great with the exception of the salinity being a little low. Could this be causing my SPS issues? I have some easier SPS and some Acros and same results. Mixed reef and most everything else seems to be doing well. Thanks in advance or any guidance on what else to check/ look for.
