Hey guys so I’m trying to get my parameters right for my tank my calcium usually sits at 500 but it’s down to 400 and I’m wondering is that ok or should I keep up with 500 and then my alkalinity is at 7.7 which it really stays at that which I’m not sure if I need to change that and my magnesium is at 1480 which I’m not so sure on that but I think it’s ok. My phosphates are at 1.5 which I know is pretty high. I’ve been keeping coral for two years now and all of them have been doing ok I’ve only kept lps and softies but I want to start with sps so I want to make sure my parameters are good
