I am a new user, and new to pool maintenance. I have a weekly pool maintenance service, but I am considering switching to a different company, as I do not have confidence in the current company including whether they are doing things to make their life easier, or making my pool better. I live in San Diego, where the water has a very high CH (about 200 to 400 ppm) for refill water. And of course lots of sun, but not too hot. If someone can help with the below that would be great. I travel for work often (just not currently) so I cannot manage the pool daily. Can you comment on the below?
1. What should be the min, target and max values for FC, TC, pH, TA, CH, and CYA based on my pool type and pool location/weather?
2. Should I be satisfied if a pool maintenance company only uses test strips? I presume not, since the accuracy is not particularly good, and CH cannot be measured, FC precision is difficult to differentiate, etc.
2. My current pool service says the right target for FC and CYA is 10ppm and 90ppm respectively. Why do you think they are targeting such high values? To make their work easier? I had yellow algae spots in May and the pool service was not keeping FC above zero but the pool service wanted to blame me for the algae as a result of low circulation time. Note the pool service thinks the pool should circulate 8 to 10 hrs per day. I have been using 5 hours per day and am estimating 50 gpm (complete guess) which is about 1.5x turnover. What should I target for circulation time, time of day, and relationship to when the pool service comes to the house? What should be the theoretical turnover? I am working on trying to estimate the pool circulation rate gpm more accurately but have not yet undertaken that item yet. Electricity in San Diego is about $0.50/kW-hr so it is expensive.....welcome to CA!
3. The pool service wants to use chlorine tabs (e.g. I am not sure if it is dichlor or trichlor) to keep the FC level higher (e.g. keep algae away). They say chlorine tabs are needed in the summer in San Diego. Is this correct? Should I tell them to stop using them? Or, instead (which is what they used to do) would it be preferable if they would add 1 to 2 gallons of liquid chlorine per week (all on one day when they service the pool)? I am not able to manage the pool every day myself as I travel for work 50% of time, and can be away for 2 weeks at any one time, or I would manage with daily chlorine addition myself.
4. I have had calcium deposits on the glass tile at the water level in the past. So I am interested in avoiding this again. To clean it with a bead blast cost $750. Since I travel, I am considering a new weekly pool maintenance service and they recommend an online analyzer and automation for liquid chlorine and muriatic acid to actively/real-time measure and manage FC and pH between their weekly visits for service, to keep FC and CYA lower, and better manage water quality to not have high CH. Should I consider this a better alternative than the dichlor/trichlor tabs? Is it a better alternative than the 1 to 2 gal per week (all at once) liquid chlorine addition?
5. With the high CH in water in San Diego, would it be normal/expected to drain the pool each season? Every other year? Anytime? Does this change based on weather chlorine tabs are used or not? Etc? What is the best water quality management option for me given I cannot manage the pool every day? thoughts?
5. I have attached testing results - does anyone see any concerns or suggestions?
Thank you for your help. I am trying to get much more knowledgeable so I can pick a better maintenance service, ask the right questions, keep a look over their work, and be sure they are managing the pool in a trouble-free way. And then also decide if I should upgrade some of the pool equipment.
Thank you. Scott
