Hi everyone,
So... I don't know if I should feel angry or embarrassed or stupid or relieved.
Had the water tested by professional pool service that opened again after the festive season and guess what I found out?
The CYA is in excess of 100ppm. I guess it will be part of my story with the price tag to go with. They can only register up to 100 for CYA. This compared to the other local pool shop tests I had to rely on that reported only 50. Go figure.
So knowing that little important fact explains why the amount of chlorine would not make a dent in the condition of the pool to try and SLAM with such a high CYA.
So no one else is to blame but me and the inconvient truth that without reliable water tests results I'm shooting in the dark.
After showing the pictures of the pool before and what it looks like now with the consideration of the amount of chlorine already used in th past three days, tests indicate iron in the water with other metals and solids from the water service centre. This must be from the algaecide and stabilizer products used and mentioned and a few commentors have brought to my attention on the forum. You know your subject matter.
I was given the advice at the professional pool service centre to never use algaecide and keep away from any form of stabilizer or chemical pool treatments that use which corresponds to the advice on the forum.
They tested all the other numbers and it corresponds to my test kit numbers plus the CYA.
PH 7.5
FC 3.0 (early this morning)
TDS 756
Alkalinity 90
CYA 100+
So in retrospect considering I did a water change of 30% and the numbers are still higher than 100, what are my options to bring down the CYA over time as I can't replace all my water at the moment as this would be too costly.
They advised I carefully follow the instruction to use hyper floculant treatment as the metals they picked up is a concern to them and some on the forum also referred to it.
They will perform a water sample test on my borehole water as they indicated the local municipality water has a problem with iron. This might have exaggerated the green tint even after I replaced 30%. Grrr.
Floc treatment:
I have bypassed the filter and treated the pool. Have added some pictures to the shared folder for reference.
Already seeing brown gunk floating on top and sinking to bottom after just a 15minutes.
I'm very carefull not to get the stuff into the filter. Got a vacuum hose attachment to vacuum directly to waste.
Will the Free Chlorine in the water be effective at sanitizing after the floc with such high CYA values?
I'll retest all the numbers on the weekend after a few vacuum sessions and share the results.
More pictures of the pool condition and some extras of the equipment.
