Exactly what do you mean when you say I'm still going to have algae?
Well, I'm speculating based on your other posts asking about funky smell and the fact that these organics have been in your pool since May. That coupled with the use of test strips makes me think your Cl levels have probably not been constant. All that info implies to me you currently have or will soon have organics (algae) in your water.

After all that, keep in mind I am GUESSING...I could be completely off base. The only way to resolve it would be a full set of test results (not strips) from the pool store to include FC, CC, pH, Alk, and CYA.

BTW, I should've added "Congrats!" to fixing your multiport hook-up. You did nice work sticking with it 'til you got it figured out.
