The ingredient you listed is a mix of EDTA (a chelant) and ammonium sulfate. Adding ammonia according to the instructions you followed produces monochloramine. MonoC is very effective against algae, but also rather irritating. It's going to take a LOT of chlorine to get rid of it.

Also, you have very high TA due to the soda ash (borax would have been a better choice to use with the "G to C", but I'm sure the store didn't tell you that!). And it looks like you've done a bit of lime softening (lowered CH), which means some of the cloudiness is probably calcium carbonate.

So . . . you need dose with 6 gallons of bleach each evening. Take a break if you have higher than 15 ppm the following evening. Continue to dose that way till your CC is below 1 ppm, and your chlorine levels will 'hold' overnight.

Also, you'll need to get that TA down. So use muriatic acid (gloves, glasses, pour close to the water, watch the fumes!) to lower the pH till you reach 6.8. Stop, and wait for the pH to climb above 7.0, then repeat. Continue till your TA is below 100 ppm. The process will go faster if you adjust your return eyeballs so they 'ruffle' the water's surface.

Once you get done with those two things, you can decide whether you want to drain and refill, or run high chlorine. Personally, I'd run high chlorine.

Good luck!
