Trouble maintaining FC, CC, and CYA levels

At the beginning of this week, I had a green cloudy pool. I was able to clear that up and was then left with a blue cloudy pool. I began testing it and finally was able to get the pH up to par after adding pH up and chlorine.
I was getting absolutely no chlorine reading, even after adding it. I decided to do the SLAM process, but I’m not sure I should’ve. The CYA was at 40 last night and was at 70 this morning. I added a little over 2 gallons of chlorine to the pool and now I have a high CYA, FC, and CC. I’m not sure what to do next, looking for some assistance.
 
You cannot safely slam without the kit. You can do harm to the pool, equipment and most importantly people.

At a minimum, you would need a k-1515 Taylor kit to slam.

Noted! I think we’re just gonna take the safe route and drain it, refill it, and start over. I now have pH up and down, stabilizer, and liquid chlorine moving forward, so I’m hoping to keep up with it and not let it get back to the mess we started with.
 
Do not use pH down, in contains sulfates and corrodes metal and concrete. It is also expensive. Use muriatic acid to lower pH.

Maintain your FC based on your CYA. Always follow this...Link-->FC/CYA Levels

I think TFP and a good kit, will save you a bunch of money and heartache...more than the cost of the kit. I've seen it more times than not.

Thanks so much for your help!! I’ll throw out the pH down. What test kit would you recommend that isn’t too expensive for a beginner? I have a 5310 gallon above ground pool. We use a sand filter system if that makes a difference in anything.
 
You are in a little pickle. You have a pool that sits in the middle of Temporary/season (1000-4000gallons) and a regular pool.

If you are willing to dump water if you get algae, get the HTH 6-way test available at your local MegaMart. In addition to chlorine and pH, it tests total alkalinity, calcium hardness, and CYA (enough for two tests). (I'd throw out the strips).

Like this...Link (ignore the robot or human, it is a link to the kit at walmart.)-->Robot or human?

Follow this guide:

If you want to avoid getting algae and having to dump and replace water, then this is your best value.
