Concrete Pool Start-Up FAQs
What do I do when the marbelite application is complete?

  1. Never use soft water to fill your pool.
  2. It is highly recommended that the pool be completely filled with water 24-30 hours or sooner after marbelite application is complete to avoid the finish from drying out. Shrinkage cracks or webbing may occur and will be visibly more apparent or mottled coloured applications if the pool is not filled quickly enough.
  3. When filling with a garden hose it must be placed at the bottom of the pool near the drain with a rag tied around the end to disperse the water (never walk into the pool). The hose must be gently placed in the bottom near the drain from the top of the pools edge.
  4. Having water delivered by trucks is a very wise option to speed up the filling process. Leo Marbelite Inc. will organize this service for the homeowner with their permission. This is an extra cost and is not included in the cost of the marbelite. (Budget $800.00-$1,000.00 depending on pool size).  

What do I do when the pool is filled with water?

Day 1

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.



Chemical Water Balancing


7.2 - 7.6 ppm


80 - 120 ppm

Calcium Hardness

200 - 400 ppm

Free Available Chlorine (FAC)

1 to 3 ppm

Total Available Chlorine (TAC)

1 to 3 ppm

Cyanuric Acid

30-50 ppm


0 ppm

Salt Level

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.

What is the proper winterizing water level?

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.
