Our marcite pool lasted form 1995 to 2015 with few problems. After testing weekly for years I resorted to "feel" and the occasional trip to the pool store (PAP) here in Florida to let them do the check. Over the years about the only "problem" we had was the occasional flare up of algae when chlorine got too low. CYA obviously was through the roof as the good old Hayward chlorinator was fed a steady diet of tabs.
About 3 weeks ago we had the pool refinished (I believe they called it a "quartz" finish). Smaller aggregate than the "pebble" finish. We like it because you get some color without darkening the finish. Here in SW Florida darker finishes simply seem to heat up the water.
So the pool refinisher left instructions only to keep PH between 7.4-7.6 and left a lot of acid to keep PH under control. Also stressed keeping TA not to exceed 70ppm for the first 2 weeks. 1 bottle of "The Blue Stuff" sequesterant, Calcium Hypochlorite (90) for sanitation and regular brushing. Used "city" water to refill pool. Only "problems" were the speed with which the Cal Hypo would disappear and the water clouded.
We've used Aquachek test strips until today to monitor. Started this morning with K2006 and here are our initial readings;
FC: 3
CC: .5
PH: 7.6
TA: 50
CH: 280-300
CYA: <35 (some residual tab may have been in chlorinator when pool restarted by resurfacer)
SI: <.05>
Switching liquid chlorine and plan to study the BBB method here. Plan to give away chlorine tabs (for beer hopefully)
Time to add 20 Mule Team? How much?
Thanks
