I had a slight algae problem, I felt slimy surfaces in a few cracks. I began my slam and have used a huge amount of chlorine.
My levels upon starting were:
TA - 110
PH - 7.4
CH - 60
My first overnight test I went from 22.5 FC to 14.5FC in the morning. Last night I went from 27FC to 23FC in the morning. Today I am having huge drops each time I test. I have used 14 gallons since I started this two days ago. Is this a normal amount for a SLAM? It seems excessive and just curious as to what is considered normal losses with a CYA level of 30-40 in a sunny location.
My second question is, how do I know if it is dead algae or alive algae? I haven't felt anything slimy or slippery since I began, but there is what looks just like dirt and debris in a few cracks and crevasses each day. It does disappear into a cloud if I stir it up but I've heard that dead and alive algae both do this. Does anyone have pictures of the two? Any surefire way to tell the difference? When vacuuming it should I do it through the filter or to waste? I backwash often and especially after vacuuming.
