Almost lime green in 24 hours.

[RussianSpy]

Hello everyone! I am new in all what concerns pools. I am absolutely overwhelmed by seeming complexity of pool maintenance. Now It literally turned surreal green in less then 24 hours.
I need some kind of realistic maintenance routine and I don’t even know where to start. Too many products, too many things go wrong with the pool. Any good advice appreciated.

Welcome to the forum!
You will need to SLAM Process. To do that, you need your own proper test kit - Test Kits Compared. I suggest the TF100 from TFTestkits.net. Get the XL version as you will need the additional test reagents.
While waiting on your test kit, add 5 ppm FC worth of plain bleach or liquid chlorine each evening with the pump running.
When you get your kit, run all the tests and post them here.
I suggest you read ABC's of Pool Water Chemistry and consider reviewing the entire Pool School eBook.
