OK, to start off I'm just a new pool owner. Our pool Was first filled with water on june 24, but pumpstation wasn't connected that time. Because there was a lot of other work around the pool (placing tiles, lot of sand work, etc.) the water became very dirty / greenish.
We thought is was algue, also due to the water not being moved by the pump. My father (a pool owner for 18 years) put in 2 pucks and 1 liter of anti-algue. We use a temorarly pump to get the water moved.
As soon as all the hosing and pump was installed we started moving the water and vacuuming. Turned out it wasn't algue at all, the horrible look of the water was lots of sand and dirt on the bottim of the pool.
Whe started vacuuming and vacuuming until all was clear.
About 9 days after putting in the pugs, I added 200 kilo pool-salt and let the pump filter for more than 24 hours.
Two days after putting in the salt, I removed the remaining of the pugs and turned the SGW on. At the moment we did our first tests with Tru Aqucheck. pH was to high (8.4) and FC to low (0.4).
From that moment I started to treat my pool as follow:
minimum of 8 hours running pump (usually from 09:00 to 17:00)
1 to 2 hours per day SWG on 100%
Since opening of the pool I used about 5 liters of anti-algue, but try to keep this as low as possible because I feel there is no need for it (supported by the info that I need less anti-algue products with SWG).
I used some pugs with 'flake stuff'. Don't now the English translation for it. It is ued to bind the most tiny stuff together so it can be filtered by the sand.
I have sparkling clear water with this treatment. There was only 1 occassion I had some cloudy water:
On a saturday monring, after a week of cold days, I turned on the heatpump. Therefore I changed the faucets on the pumpstation. I closed the faucet on the inlet of the vacuum-hose (normally the pump sucks water through 2 skimmers and 1 vaccum connection), and turned the bypass to the heatpump half open. I pumped and heated for 8 hours. Next day I did the same. The 3rd day that heatpump was turned off, but normal circulation still was going through bypass/heatpump.
At the end of day 3 I noticed the water was white cloudy/misty. I closed the bypass and opened the valve of the vacuum connection. Now the pump was sucking a lot of more water. I vacuumed the entire pool, added half a liter anti-algue (just to be sure) and kept pumping for the rest of the night. Next morning normal pumping hours and at the end of the day the pool was clear again.
At this moment I check my water with the Tru Aquachec and act based on the values. One thing I'm struggling with is that my pH keeps rising every time. I have to add 6 coffecups once a week to get done from 8+ to 7.2 - still have to test the H of tapwater used for adding water after backwash.
Most of the time 1 to 2 hours SWG per day is enough, when it gets to low I run it longer.
I have the Tru Aquachec, but I finf it to fluctuating due to the used method (use light to interpret the values) the device uses. I haven't found the recommended tests in The Netherlands yet, so I'm looking for a seller to ship to me as low as possible.
Is the methodm, and numbers, mentoined in TFPC usuable for countrys outside US? We have other climate, conditions and water overhere.
My pool is 8 meters by 4 meters and 1.5 meters deep, so roughly it has 42.000 liters swimmable water.
Thanks for helping out.
