victoly Posted June 11, 2013 Share Posted June 11, 2013 That sounds more to me like water quality than flow. Check parameters, change carbon, water change is my remedy no matter what the parameter Link to comment Share on other sites More sharing options...

haze152 Posted June 12, 2013 Share Posted June 12, 2013 + 1 on mag being super low 1200 -1300 you can get mag dosing at most LFS Link to comment Share on other sites More sharing options...
haze152 Posted June 12, 2013 Share Posted June 12, 2013 It should not be that low after water change what kind of salt did you use? You may want to have that checked again just to be safe before dosing. Link to comment Share on other sites More sharing options...
victoly Posted June 12, 2013 Share Posted June 12, 2013 what should i do to bring it up dry dose magnesium! you can get it from any of the LFS or BRS. I kinda doubt that low mag killed your clam though. Link to comment Share on other sites More sharing options...

Wardlaw Posted June 12, 2013 Author Share Posted June 12, 2013 I mix salt and rodi in 55 gal with lid and leave to sit for sometimes 30 days. You think that matters? Link to comment Share on other sites More sharing options...
victoly Posted June 12, 2013 Share Posted June 12, 2013 probably not. not all salt batches are created equal. Link to comment Share on other sites More sharing options...
Derek Posted June 12, 2013 Share Posted June 12, 2013 While I do not personally keep SPS, it is my understanding that they are feeders of smaller particles in the water column. Lower flow would mean that the bigger particles are not staying suspended in the water column and would be more likely to settle on the bottom or on rock work and cause higher ammonia and thus nitrite and nitrate. From what I am read SPS seems to prefer high flow so that could definitely be a determining factor in why the corals retracted. I tend to think of it like this, "What happens to me when I fall into cold water? Oh, I freak out because it's cold!!! ::shivers::", i.e. any change in the environment is going to cause stress and thus a reaction from the inhabitants. My recommendation is to wait a few days and see if they get used to it. Admittedly that is advise from someone who has never kept and SPS coral.
