I've been at my new place for a few weeks, but just now have had time to dig into managing and maintaining my pool. I've had clear green water since the pool was opened and know there are things I need to do such as checking the CYA level (don't currently have a test kit for that), and possibly getting the water tested to figure out if the green is caused by algae or metal.
What I'm hoping for is someone to point me the right direction on what my first steps should be to get the water (see attachment) that pristine blue, without the benefit of having full data available. I've run across several different options, including conflicting ones from the pool company I've had come out so it is a bit confusing. I've left some data below, but not sure if it's enough for the members to help, but hoping given the pic of the pool someone might recognize the most likely cause.
Pool: Approx 10 yr old Gunite - Pool opened 4 weeks ago
System: Hayward SwimClear Cartridge filter and Hayward Pump
Backwashing: Done twice at two week intervals. Filters are fairly clean but lots of gunk in there. Unsure if previous owner ever backwashed
Pump: Run 6 - 8 hrs. daily and pool not currently being used
Generator: Between 3500 - 3800 salt to chlorine
Cleaning: Vacuumed and manual skimming about every other day. Sides brushed about every week
Chemical tests: BioGuard 1200V Multi Test (results approx)
Chlorine Residual - 1.2
PH - 7.8
Acid Demand, Alkali Demand and Total Alkalinity all within acceptable parameters
Based on the pic and the above data, anyone want to guess (and know it will be a guess until I can get more info like CYA) as to what should be my first treatment to get the color of the water where it should be?
