You would indeed think so, or that the Belgian tap water come with free CYA.... At the moment I doubt almost all measurements. We will see once the K-2006C kit arrives to compare results

Just replaced 40-45% of the water to get to a new reading of.....CYA 60. Honestly quite disappointing. Other disappointing thing is that the pool went from clear to green. On the other hand the K-2006C kit has been ordered and should be arriving the 27th...in the US, then we have to see how...

....After more pumping out water and replacing it with fresh water: CYA 79... :cautious: Now it has gotten to the point that I am pumping out the water. Made a new (temp) connection to a holding tank and will try and almost do a complete new start.

A couple of days out of the country. No chemicals added. First focussing on getting CYA to an acceptable level... Unfortunately after all the vacuuming to waste and replacing with fresh water CYA is still only at 77... As for the testkit I will take @mknauss route and order from the US. As the...

Thank you for the idea @mknauss Will check them out. Would be an idea (and not only for this test-kit)

Due to the fact that we are not connected to standard sewage the draining the pool to waste has to go in stages. Still slowly lowering the water level before filling it again. In the meanwhile trying to get hold of the K-2006C kit everybody seems to be so positive about. Analizar Agua in Spain...

Ok....after replacing 1/3 of the water and using Shock which I was told by the seller it had limited influence on raising CyA. I now know that CyA has actually shot to 90-96 :cry: (had to measure it twice as I could not believe it initially). It turns out that it does somewhere on the container...

Hi mknauss, You are correct there still is some kind of algae issue. The pool was green at the beginning after the winter season. The leaves are all out of the pool and finally the pool is kind of clear. Yet I still have sediment in the morning. Vacuuming to waste on a (almost) daily basis.

Cheers for the link. Their site is down for the moment. But will check it next month or so. Estamos realizando mejoras Volveremos a estar disponibles muy pronto. Nos vemos en poco tiempo. Fair enough. Probably is something of getting used to as well. Will use this method until I can source the...

Date Temp C/F TA (ppm) pH fCl [FC] (ppm) tCl [TC] (ppm) cCl [CC] (ppm) CyA (ppm) 23/APR 12 / 54 113 7.25 3.60 5.25 1.65 88 24/APR 12/54 113 7.41 3.21 5.49 2.28 85 So the measurement that I gave was the tCl iso cCl. Forgot to subtract. See the table above for the "correct" readings.The one...

@mgtfp Cheers for the advise. Will have a look. Found it in the USA, the shipping and importing will be a little thing. Getting supplies in future might be tricky as well. And what I prefer from the Pool Lab is that I get an exact result. Here it seems with color it is more a ballpark estimate...

Hi mknaus, Will do a new measurement today. I was quite surprised with the outcome as well, so we will see if it is indeed off or if the measurement done with the tablets went wrong.

So the results: Temp 12 degrees Celsius 54 F TA 113 ppm pH 7.25 FC (fCl) 3.60 ppm CC 5.25 ppm CyA 88 ppm Some work ahead...

Temp 12 degrees Celsius 54 F TA 113 ppm pH 7.25 FC (fCl) 3.60 ppm CC 5.25 ppm CyA 88 ppm Some work ahead...

Will hope to post a table with all the values somewhere tomorrow. @mgtfp Thank you for the advise to read on Chem Geek's thread. Will try and find it.

Just got the tablets. Will test the pool and tap water tomorrow

Hi Casey, I really appreciate your post! Hope to have the CyA tablets tomorrow and then will do a full range test. For the moment I am starting up the pool after the winter. Was kind of green. So after taking all the leaves out and vacuuming to waste quite a bit the worst is gone. Although the...

Just a little side note; If FC level = fCl ppm ≈ fCl mg/l that would mean with a CyA of 60 my fCl would have to between 7-9 mg/l However legally I am not allowed to exceed 5 mg/l as a private pool. Does that then mean I am forced to have the CyA at 30?!:unsure:

Hi mgtfp, Thank you for your detailed answer. I did come across the FC/CYA Chart before. Yet had no idea that FC 4 would be equal to fCl 4 ppm, when I then see the SLAM values even go up to 24 (for CyA of 60) I am chocked in a way. At the moment my CyA tablets are out so I can not test the...

Cheers Casey, Lovely car by the way. We are using a digital tester Pool Lab 1.0 which uses DPD N'1 tablets to test for fCl. The values I get are in ppm. And not these magical FC levels. So just curious about the conversion.

Hi all, Due to the lockdown last year we decided to buy a on-the-ground pool to see if we would like it. Although the climate in Belgium might not be ideal, it is ideal to keep 5 kids happy while unable to leave the country. It is a pool of 10x5 m with a capacity of 50.000 liters. Yet as it does...

Hi all, Sorry to start of with such a basic question. Yet I read a lot about FC levels. Like FC 4. Yet my tester displays fCL as ppm. So I believe I should be in the 0.5 to 2.5 ppm range, but how does this relate to the FC 4-9 range? Again my apologies for my ignorance
