Hey everyone I’ve been having issues with my torch corals I have bought two and both died within two days of being in my tank my calcium and alkalinity and salinity are where supposed to be? My Mg is high at 1560. Could this be the reason why they are dying if so how do I lower it I do a water change once a week of 25% in a 75 gallon tank.Can you some help here please because that’s $200 wasted the rest of my coral is going great it’s just the torch’s
