I moved into a home with a pool. I moved in about a month ago and had issues with vacuum leaks at the plumbing and a leaking filter. Home warranty finally fixed those issues so now I’m I the process of vacuuming up the bottom with a Zodiac MX8 and cycling the pool water. I also started testing the water quality and seen something unusual when doing the CH test. I noticed the test sample clumped up. Is this something to be concerned about? See picture
A bit of history of the pool. About a week after moving in we experienced a bit of rain. Without a properly working pump system I was unable to cycle the water. A few days later I noticed black spots. I did the finger nail test and figured it to be black algae. I then toss in four bags of Power Powder from the local pool store, which seemed to stop further growth. The black alga remains and now with my newly arrived TF-100 test kit, I proceeded to test water quality to present to all of you for some advice and remedy of black algae. My concern at the moment is the clumping of the CH test sample. However, after showing you all my test results, it might reveal other issues. Can someone please advice what the clumping is?
Test Results
FC = 3.5
CC = 0.5
CYA = 55
TA = 160
CH = 300
