Your neighbor has been very lucky, but I certainly wouldn't follow his lead. When your pool is green, you need to raise your chlorine to shock level (that's based on yourCYA-- see the link to the "best guess table in my sig) and hold it there until the algae is all dead. By shocking every two days ( how do you know the chlorine level was high enough?), your chlorine was drifting up and down, and the algae was never completely killed off, let alone filtered out of the water. Once you kill and filter all the algae, then you need to make surre your chlorine levels stay high enough in the pool so the algae doesn't come back. That will be easier to do once you have CYA in the water to protect your chlorine from the sun.
Once you add CYA, it takes up to 4-5 days for it to dissolve, so don't expect it to show up before then. Also, if you backwashed the filter after adding it, it all just washed out and you'll have tostart over.
Just a warning about the tabs--the ones you are using contain copper, which is not a good thing to have in the pool. When people start having green hair and fingernails,andgreen stainingon the liner, copper is the culprit. Normally people blame the chlorine, but it's the copper. I woild strongly advise you to switch to tabs that don't contain copper.
