Hi,
Never owned a pool before, and since purchasing the home 12 months ago, the pool has been maintained on a monthly schedule by a local pool shop.
At this stage for me, it's all quite intimidating but I've done my best to read up and collect as much information as I can.
So, I'm looking for some advice on how to proceed.
I've purchased a salt water test kit from Clear Choice Labs, and have the following results:
CYA - Low reading (ie < 30 ppm)
PC: 2.5 ppm
CC: 0.5 ppm
pH: 7.8
TA: 75 ppm
CH: 350 ppm
Salt: 4200 ppm
using PoolMath, using TFP targets, it's suggesting:
FC: 112g 65% to target 4
pH: 309mL 32% to target 7.5
CH: 2900g Calcium Chloride to target 400
Stabiliser: 2100g stabiliser (based on a guess that CYA was 15) to target 70
In addition, the pool pump was out for about 3 days for repairs last week, and since I've noticed a very small patch of green algea (otherwise the water looks clear to me).
If it's relevant, over the past 3 months, coming into warmer season, the pool shop has added the following:
August: Acid, Algeacide
September: 2 x 25kg Salt, 500g Chlorine, Starver
October: 1 x 25Kg Salt, Acid
Also, I'm not entirely sure what it means, but the SWG always seems to indicate it's running in the "high output" zone. Is that because the CYA is so low?
So, do I need a "SLAM"? (this would be very intimidating first step tbh)
How should I go about increasing the CYA levels?
Many Thanks
Matt
