Thanks. Fingers crossed. I'm not out of the woods yet. I put in clean grids a few days and the start-up pressure was around 15- now hovering between 19-17, bouncing back and forth - that's typically a sign that I'm in for a fairly short cycle. Last one was 18 days...that's ok...but was hoping for a full 3 weeks. I won't be able to make a final determination on a conversion next year until end of season. I'm extremely happy with the water clarity - can't recall a season with baqua that has resulted in such consistently clear water so I think the 1/2 lb. of Line Clean, follwed 3 days later by 1/2 gallon Oxidizer, then the Line Clean again 4 days later, etc. seems like it just might be a solution to the white water mold / slime issues (being that I've barely seen any since opening - big difference in how the bottom and sides feel). Remaining issue is the filter cycles. I clean out the skimmer sock frequently, so hopefully that's helping.
