START UP GUIDE
Step 1 – Start filtration system.
Step 2 – Adjust PH to 7.2 ppm by adding muriatic acid. (Always pre-dilute chemicals by adding it to a five (5) gallon bucket of pool water).
Step 3 – Add a sequestering agent to pool water. Recommended brand is Jack's Magic - Magenta Stuff. Add 1 bottle per 40,000 litres of water in your pool.
Step 4 – Thoroughly vacuum the walls and floor to remove calcium dust with a non metal brush vacuum head, not a wheeled unit.
Step 5 – Backwash filter unless vacuuming on waste.
Step 6 – Brush walls and floor.
Day 2Step 1 – Brush pool and vacuum if calcium dust is still evident.
Step 2 – Test PH to read 7.2 -7.6 ppm, test Alkalinity to 80-120 ppm.
Step 3 – Once PH and Alkalinity have reached those levels adjust Calcium Hardness levels to a minimum of 200 ppm.
(when adding CACL2 always pre-dilute and add in 10 Lbs increments morning and afternoon).
Day 3Step 1 – Brush pool and vacuum if calcium dust is still evident.
Step 2 – Test PH to read 7.2-7.6 ppm. Test Alkalinity to read 80-120 ppm. Test Calcium Hardness to read 200 ppm.
Step 3 – Add pre-diluted chlorine to achieve 1.5-3 ppm. No salt should be added for 28 days.
After the third (3rd) day the pool should be brushed daily for fourteen (14) days especially if calcium dust is still apparent. Water chemistry balances should be monitored often especially during the first 28 days. Listed below is a chart illustrating chemical water balances for a long lasting finish.
ALWAYS PRE-DILUTE ALL POOL CHEMICALS BEFORE ADDING TO SWIMMING POOL, BY ADDING THE SUGGESTED AMOUNT OF CHEMICAL TO A 5 GALLON BUCKET OF WATER
7.2 - 7.6 ppm
80 - 120 ppm
200 - 400 ppm
Free Available Chlorine (FAC)
1 to 3 ppm
Total Available Chlorine (TAC)
1 to 3 ppm
2500 - 3500 ppm (Salt Chlorination Only)
These balances should be kept as an ongoing maintenance routine to ensure the longest possible life of your new pool finish. Failure will result in possible scaling, etching, or peeling of finish over time.
Once it is time for the pool to be winterized it is necessary to drain the pool below the return outlets. Once the directional eyeballs are removed and the plumbing lines and equipment have been blown with air, threaded plugs should be inserted tightly into the return threads. At this point proper winterizing chemicals should be introduced and a good (hole free) pool cover should be placed on the pool. The water level should be raised two (2) inches below the tile line. This will reduce marbelite frost damage to exposed areas since the weight of the snow will raise water level to the waterline tile area.
