Reddit mentions of Jed Pool tools Inc 00-481 Standard Dual Test Kit

Well - first off, everything is much newer and in better shape than I expected.
Like I said you should be able to get copies of all of the manuals ( if you do not already have them) on line. In particular the pump/strainer and the filter.
If the pool is just green, and not too much real debris, you can probably get it running as soon as you fill it up. Even if you keep it covered, I would get it up an running so you can learn about everything now.

Pics - 1&8 Muriatic Acid, very strong, and it is hazardous, but also very effective. I prefer using this. As for the condition, it is probably OK...

2 - Fountain , yes decorative only

3 - Liner cleaner, I am assuming the pool needs to be empty to use this. If there is a date on it and less than 2-3 years you could keep it. You may have a ring on the liner where the water level is now. This may help. - but I have not used this and do not know how damaging it is if a little gets into the water.

4 - > Looks like a handle, perhaps for maintenance of something. ( ref the manuals)

5 - No idea, looks serious and like a lot of it. Check the manuals.

6&10, 13-no label, double wrap in heavy plastic bag, and trash it. ( if inside it is tablets then it is chlorine - I would keep tablets, but any unmarked powers, granular, liquids - trash)

7- Pretty sure this is the vacuum cleaner attachment, you set this on top of the skimmer, and connect the vacuum hose for suction.

9 - Yes it is a part you probably want, it may be a discharge fitting to help with draining the pool.

11 - the safer alternative to the Nuriatic acid. Worth keeping.

12 - just an another alternate. Since it has a label it should say specifically what the chemical is. ( Keep for now)

14 - no idea, too small to be for the pump. Perhaps a charging cable for the fountain?

15 - I agree - looks to be the same part, but one may have come with the skimmer, and one with the vacuum. Keep

16 - Same ( they may fit different size vacuum hoses, etc.)

17 Keep

18 - too blurry, but also looks like lube ( did the previous owner have a boat?)

19 - the pole on the vacuum ( background) has spring buttons, so the pole is used for the skimmer net, brushes and the vacuum.

20 - no idea - have fun

22 - that looks like the type of brush used to clean a boat ( more evidence) If he had a boat the Lube in 5 and possibly 18, may also explain 20)

23 - the hose going to the Strainer Backet will be connected to the SKimmer on the side of the pool. ( that is the intake,)

• The other hose should go to the filter
  
  24 -25 - Yes - the Strainer basket, pump and pump motor are all one assembly. ( Is the electrical cord terminated with a reguar plug??)
  
  Looks to be in OK shape - but not the cleanest / neatest assembly.
  
  26 - Yes - filter
  
  27 - Pressure gauge ( indicates how dirty the filter is, but also that there is water flowing - etc)
  
  28 - Paper cartridge filter ( what I can see looks to be in good shape) - when you get up and running this should be very low to little maintenance over the course of a summer. But for now - get up and running as it is, when the pool clears up - you may want to remove and hose this down. - will take about 20 minutes.
  
  29 - Yes - I have an in-ground with paper - and have been amazed how well these work and how little maintenance. I have not replaced mine, I give them a good cleaning in the fall when I close.
  
  30-31 - Yep
  
  32 - Yep - check both ends of the hose for the fit.
  
  36 - Yep ( may want to replace this)
  
  37 - this one is newer and a little prettier - and has the deluxe termo!
  
  38 - Skimmer basket - take to the pool store and get a new one.
  
  39 - Plug for winterizing - this will plug the wall nozzle ( return)
  
  40 -- Bottom of the Skimmer - see the same plug type.
  
  45 - Skimmer net (doe not go IN the Skimmer) just what I call it...- not perfect, use this for the clean up and get a new one for regular maintenance in the future. ( so you do not beat up a new on doing the initial cleaning)
  
  OK -- so like I said not too bad....
  
  Connections --
  Side Skimmer hose - to strainer basket on the pump. Exit of the pump with hose to the filter housing, will need to check the manual for which in the inlet and outlet on the filter housing (probably labeled though). Hose from exit of filter to the nozzle on the side next to the skimmer ( Pic 43). ( You should have three hose sections - to do this)
  
  If you can get a small water pump, like a sump pump wihhout the float switch. LIKE THIS - you will use this over the winters to keep the water off of the cover in the future. ( There are automatic ones - but I have found that a basic pump like this - and turning it on manually lasts longer and costs less - it is OK to have water on the cover for a short period of time, you just do not want it on there to grow stuff collect debris)
  
  Pump the water off of the cover, then remove it.
  
  Hard to tell really how bad the water in the pool is - but I would probably go ahead and use that and top it off, instead of completely draining and refilling.
  
  If you want to empty it completely - you can use the pump, but may need to rearrange the hoses to get one long enough to go over the wall and to the bottom. ( I guess you could hook up the vacuum - but this will slow down the process)
  
  The important thing is to make sure the pump has water when you turn it on. You will probably have to prime it, by filling the strainer basket with the garden hose and then replace the cover.
  
  Monitor the pump when starting up and make sure it does not run empty after this for more than 1 minute or so - it may take some time to get the water flowing if you are using the vacuum and the water level is too low.
  
  Put the hose in, start filling,
  
  

• Go to Kmart or other store and get 3-4 1lb bags of Chlorine Shock. They MAY have the skimmer basket ( other wise go to the pool store for that).
  
• • 2 ( 4 !) lb Baking soda ( yes regular baking soda)
    
• Get a Chlorine / PH test kit ( LIKE THIS)
  
  You can get the water tested now - typically free at the pool store, but you will be making a few adjustments and at first, we just need it chlorinated and cleaned up.
  
  30' round 52" pool is ... 21K Gallons. I did not realize they had so much water! - anyway the pool store will want to know this and they typically will set up a record in their system. This will help them tell you how much of the chemicals you will need in the future. But do not let them sell you a bunch of chemicals right now - the water is so out of balance right now I do not think a test will be very useful)
  
  If you are not going to completely drain the pool, once filled and connected, add 2 Lbs of the Shock. -- and start running the pump. I would add the 2lbs of Baking Soda now, but others may disagree...- actually 21K Gal you can use 4 lbs.
  
  Once running for 3-4 hours test the Chlorine and PH , keep CL above 3.0 for a day. - I am pretty sure you will see remarkable difference in 1 day.
  
  OK - I got to go back to work - haha
