I followed the seachem marine buffer 8.3... One teaspoon to 40L .Tank was doing fine till I found a coral started to bleach.. Read abt it then proceeded to check ph lvl.. Which was 7.4 via ph pen. I then bought product and dose amt w tank water mixed. After 24hrs I measured again .. It's 8-8.1. Then all hell broke lose... One by one dying(livestocks) not corals which seemed recoluring back after 72hrs....my question is , are the ph lvl Frm LFS is low?? Below 7.5?..
