To clean up an algae outbreak you MUST know two numbers....
1. CYA
2. Chlorine number way above the 5FC your tests are able to measure
These tests are included in the TF-100, TF-50, and the K-2006. You could take the 5 way kit you have, and add on a FAS/DPD test from here,

The only way you will clean that up is via the SLAM PROCESS.
