Ok. I sometimes think the 'firehose of help' can be a little confusing here...so to that end...breaking it down a bit (and if this is too basic, apologies in advance!!)
- Step 1 - Make sure nothing gets any worse
- Step 2 - Figure out where we are
- Step 3 - Come up with a plan to move forward
You're on step 1... Adding a known amount of Liquid Chlorine (Bleach) will stop any algae getting a foothold (or anything existing getting worse) until you can accurately test your pool using a good test kit. You want plain bleach - no additives. Hardware stores or Pool Stores usually carry it as Pool Shock - it should ONLY have Sodium Hypochlorite as a listed ingredient. no Dichloro-, Trichloro- or Calcium Hypo- whatevers. This stops you adding stuff you don't want until we know where we are.
Your pool is basically the same size as mine - you will probably need about 1 gallon of 10 or 12% Liquid Chlorine per day. Pour it slowly into the pool where the water is coming back in from the pump. This avoids any potential for concentrated chemicals damaging any of your other equipment. Don't do anything else for now !
Update your signature with all the stuff you can identify - it makes the brain-trust happy when they can figure out what they are working with
Step 2 - Once the kit comes, post a full set of tests :
FC - Free Chlorine
CC - Combine Chlorine
CYA - Cynauric Acid (Stabilizer)
PH - Acidity
TA - Total Alkalinity
CH - Calcium Hardness
As you have a SWG, you should get a Salt test kit too - knowing what your salt level is will be useful when we get to using the SWG to maintain your chlorine levels longer term. The Taylor K-1766 kit will work. In the future, you may wish to consider kits from
TFTestkits.net - They are generally better value, and are curated to be more in-line with the testing methodology practiced on this forum.
Step 3 - Well, we'll get there, but if you want to see the success of the process, check out
How clear is clear ?
