My bad for the late response but my water is 0 ammonia 0-20 nitrate and 0 nitrite hardness is around 150 chlorine 0 alkalinity is around 30/40 and the ph is between 6.8-7 and the reason for the algae fix was because I had some growing on my driftwood and ornaments because natural light comes through the patio blinds but today he’s back to normal not a 100% but better than he was I would say he was deathly dying yesterday but can someone send me a message on how to go to the illness forum because I received a message about my thread because I thought I was asking about can bgk be in brackish or just aquarium salt use period?
