I have a 91 gallon red sea reefer upgraded about 3 weeks ago. pH has been fluctuating between 7.8- 8.16 (approximately based on apex pH meter will post screen shot of graph)
I had been using seachem stability as my bacteria (also have a bright well bio brick from my previous setup so imo cycled but ????)
So since I am starting to get a brown film that grows like string but disperses when it is touched and I had recently been researching if the stability actually works and how can it be fresh and marine all in one I came across a talk by DR. Tim from 2019. In that talk he basically proved my thoughts true that the marine components in that bottle are not likely to replicate in this system.
So like a good aquarist I went ahead and got me a bottle of eco balance from DR. Tim over night the pH did it's usual up into the 8's then fell .2 lower then usual to below 7.8
So I'm guessing that there is absolutely something different in this bottle then the other one.
Having said alllll that. I am also having issue with my kallwasser solution being dosed reliably. I just made a new schedule for that to dose every hour. 23ml per hour for 24hr period. (This needs to be adjusted to offset the rise and falls but I need it to actually go into the tank first)
Did the Bacteria cause the pH drop and is this a step towards solving my "problems"
Lightly stocked 8fish 2 urchin 2 conch & 12 coral frags (which have grown more in 3 weeks then the 9months in their previous setup)
I didn't want to upgrade this soon but I had an issue with a stand in another tank and the old salt tank had a siphon overflow that liked to not work. So push shove here I am!
Thanks in advance!
