Hello, I am new to this forum so I hope I'm doing this correctly. Here are my pool details;
In ground pool built in 2005, Vinyl, 18 x 39, SWG Aqua T-Cell 15 (currently set to 60% chlorination), timer is on for 12 hours and the pool probably gets about 8 hours of direct sunshine each day. Pool is about 24,000 gallons and has a Hayward Pro-Series sand filter.
I'm in the Boston area and last season my pool store gave me some very bad advice, which lead to my kids not being able to use the pool for the last 3 weeks in August and set me back almost $200 in chemical costs (yes they persuaded me that a high phosphate level was my problem). This season I vowed to become more knowledgeable about my pool, even though Chemistry was never one of my strengths. So far it's been a great summer and the pool clarity looks very good.
Having read some of your advice on this site I wanted to raise my FC level to between 3 or 4 , as is recommended for SWG pools. Ideally I should be running my SWG at between 40/50%, right now it's at 60% and just keeping up as FC readings in the a.m. are low having been off all night. My local pool store said my CYA needs to come up to 70 or 80 to make that happen. Again having read the posts about the mythical chlorine lock and suggestions that for SWG pools the ratio between FC and CYA should be 5%, I'm concerned that by adding more conditioner/stabilizer I will need to increase my SWG% higher to satisfy the chlorine needs.
My goal is to keep my pool in it's current condition without working my SWG working too hard, it's still the original installed in 2005. What do you recommend I do to raise my FC level, so I don't have to keep raising the SWG% or running Super chlorinate too often?
FC = 2.47
PH = 7.8
Alk = 37
CYA = 61
Salt = 3100
Pool temp averages between 79-82F (I have a heater but only run it at beginning and end of season so it's not on at the minute).
