Been a long time. Merry X-mas belated and a good new year to you all.
I just want to report on what I have learned so far since August after I managed to get best water clearity ever.
The pool have been busy with divers since October to December. About 3/4 days a week with up to 6 divers.
I been getting rainy season starting since early October. I practicaly been hands off the pool and leave everythig to my pool boy due to work.
About early early October I have told my pool boy to raise the FC level from 2.0 - 2.5 to 3.0 - 3.5 due to the increased bather load and lots of rain. CYA last reading in Agust was 25+-. In fact according to the log book the pool boy without my permission was raising the FC to 4.5 up to 7PPM in order to bring back maximum clearity middle of November. I did not swim in the pool entire September, October and early November. I swam twice late November and early December only.
No CC was ever recorded but I was unhappy at the water clearity early December to Christmas. However pool was so busy with divers and the rain was getting worse, nearly every day with heavy rain. I was mainly out of town then.
Anyhow I would like to report the summary :
Note : The ionizer use has been suspended since October. The anode/catahode are too expesive now. I was asked to pay US$275 for just a pair.. no way dude...
01. With 4-5 FC and water being cloudy, while no CC can be read wit TF test kit, my nose can smell the chlorine in the uncomfortable sense. I can also feel it harsh on my hair. My logbook showed that with very clear water ( less visible bad stuff that is ) at 4 - 5 FC chlorine smell can hardly be smelled.
02. For the past two weeks my Hayward Catridge filter has been trapping greenish dirt, so it must be algea. Usually its the 1 micron Slime Bag that always gets the greenish dirt. So my cloudy water is algae bloom on the way.
03. I recalled my pool when the water was very mildy cloudy, and zero CC, I could smell some chlorine even at 3.5 FC. This doesn't happen when water is maximum clearity.
I just bomb the pool since 26th Dec 12PM with up to 19ppm. I also discovered yesterday that my CYA has dropped to lower than 20, how low I can't tell. The log book showed that for almost two weeks my pool daily FC lost was high, +2PPM region. Compared to 0.5 and 1 PPM maximum in non rainy days and very clear water. Usually 0.5 PPM when divers use the pool and 0.5 PPM when rain comes, so 1 PPM was maxed wth sunlight loss included, but then it was at 25PPM CYA as per August.
This morning the water is already close to 90+% of its top clearity after 90 hours of both pump running and bombing at average 14 PPM FC ( 19 to 10 PPM swing ). At 05:45 AM today with 8.5 PPM FC and CC at 0.5PPM ( less actually ) , the chlorine smel was mild and not the intrusive kind as when water was cloudy and at 4-5 PPM FC with zero CC. 6 hours per turnover is what I get with both pumps running.
I think I will start trusting my nose more and how my body smell and feel after a dip in less than well balanced chlorine level in the pool , it seems that I can smell FC being consumed but while not yet being registered as CC. It has a disctinct uncomfortable chlorine smell.
The frequent rain been throwing me off. Since 26 Dec, some nights I loose 2 ppm FC and today I loose 5PPM FC between 6PM ( dark already ) yesterday to 05:45 AM this morning. The CYA being lower than previous 25PPM also seems to confuse me on the FC loss due to sunlight and whatever is loss fighting the cloudy water.
I will give up the use on the silver & copper ionizer, its effect its not worth the dollar spent compared to the ozone I have. My ozone system is so much cheaper and more effective.
Extensive rain is a bigger disaster compared to heavy divers load. Heay rain and heavy divers load is a REAL disaster. Since my pool gets a bit of dirt run off from the side building during rain ( sunshade water drain not too good during heavy rain ) and the sunshade accumulate so much dust/ pollen and what ever baddies too.
I am limiting the use of the pool to 4 days a week only in this rainy season, its the west monsoon now.
I am also trying to set up a schedule where 3 weeks of use and 1 week of rest for the pool per month during this rainy season, so that the 4th week I can bomb my pool. This way I can maintain peak clarity at all times.
My log book showed that water clearity started to fall a bit ( perhaps obvious is a better word ) after 60 days of maintenance profile suitable for dry season, if used in the current wet season even with extended pump running time.
I think the rain have brought to my pool some chlorine resistant baby algae more than ever. Strong winds in the rainy season may also have contaminate the pool with baddies I don't usually get. Sad... .
The good news is that with both pumps running and since the installation of the ozone, I can get back water clearity from a cloudy situation ( water visibility less than 9 feet ) within 90 hrs/ 4 days. This is so much better than before the ozone installation where 1 full week is what I need with both pumps running to clear cloudy situation but still I can't never get that final very sparkling water.
It seems in the topics like my country, the bather load profile and the amount of pollution I have in my area, water clearity and especially my nose can be the best indicator as far as bad things in the water "coming out".
I am getting to know my pool better each day now, more so for rainy season maintenance profile which I never documented properly prevously. Thanks to all of you seniors and members at TF.
Once again, have a great New Year to everyone...
