I haven't opened yet (Tuesday is the day) and meanwhile I keep FC and circulation using sub pumps at 3000 gph.
CC < 0.5
0< Ammonia <0.25
I also added some 60% polyquad. Before I added the alagaecide pH was steady at 7.3 - 7.4, but after that it drifted to 7.7-7.8. Is this a coincidence?
We've also had some rain but rain here is acidic.
