Hi Lyn! Welcome!
It's crazy overwhelming isn't it? It will get better. It really will.
I'm not going to throw in a bunch of advice just a few comments that I hope will help.
We won't throw our hands up and give up. You can ask as many questions as you want. We'll answer.
The kit really is worth it and it's necessary. It keeps you from wasting money by throwing in chemicals that you're not even sure you need!
Liquid Chlorine is Bleach is Liquid Chlorine. I've almost exclusively used Great Value (Wal-mart brand) Up & Up (target brand) and a local grocery store brand. They all sell for about $2.69 - $2.99 for a 121oz bottle. The percent is lower than the more concentrated "liquid chlorine" but I find it to be more convenient to just grab it when I'm at the store.
Testing your chlorine is really easy. You'll see when you get the kit. You get your sample of pool water. Drop a little scoop of powder in which turns it pink, then just put in the test drops 1 at a time until it turns clear again. No guesswork and no science background needed. Just count drops.
A lot of people have started out where you are. Heck, my pool was a disgusting green mess last year. (I hadn't discovered how to do it the TFP way yet!) I couldn't see what I was doing but I just kept scooping stuff up and taking it out.
We can absolutely definitely help you take control of this thing! You ask us what you need to and you'll learn along the way. The first thing is to get a good testing kit so you can know where you are and while you're waiting just keep scooping that gunk out. You can't see it but just keep dragging that leaf net around the bottom. Anything you can get out will help down the road. Anything that's left will be taken care of as you go!
Believe it or not, once you have a kit and can post up test results it will actually get a whole lot simpler. With test results we can tell you exactly what to do one step at a time. Exactly what amount of "stuff" to use. Exactly how to put it in. Exactly how long to wait before testing it again.
Pre-kit it's more trying to give you the idea of the process ahead which is a lot to take in but one step at a time it really is a very simple process.
We don't want you to waste any more money! Most of us have been there and we know what it's like. Chlorine is a consumable item so although your pool company dumped a bunch in there the green monster ate it! The reason we use the test kit is so that we don't waste the chlorine and the money we spend on it. We want it all to go to good use so we need to know exactly how much you need to start and most importantly *FINISH* killing off the algae and anything else that's lurking in there. No guessing.
My few comments turned into a book!
I'll close my little help session with this: (lol)
You're starting at the hardest part. It only gets better from here. A SLAM (especially starting from a swamp) takes some time and patience and a whole lot of bleach **BUT** when you're done and your pool is sparkling you'll move into maintenance mode which is really really really simple. Don't let the amount of bleach/chlorine needed for the SLAM scare you. Normal maintenance is much much less. You won't be going through tons of bleach anymore. That's only to take back a swamp from the algae monsters!
Stick with it. We'll stick with you! The overwhemingness (new word!) will go away. It always does!
Thanks for reading my big long book! Welcome again!
*ps*
We can even help with things like identifying what type of pool surface you have, what kind of pump, what all the plumbing does etc. There are a lot of people here with a lot of knowledge. If you don't know what something you have is...take a pic, upload it to a photo sharing site like photobucket and post it right in this thread. Someone will know what it is and what it does and how to use it!
