I am treating GHA. I used Fluconazole before I took my tank apart and cleaned it with really no significant results, however the GHA came back really quickly, so I need another way to remove it. This time I used 150% of the recommended dosage and the GHA turned brown and has died back in some areas, but it is still really difficult to remove from the rocks. I have done two 20% water changes a week apart after 5 weeks and the GHA remaining is just beginning to turn green again.
Can I treat again at full strength now or should I run some Purigen to remove any residual Fluconazole before treating again at full strength? I'm not sure what the consensus is on how long it takes Fluconazole to break down. From scanning the thread, it seems that it is not removed by carbon, but it is removed through the protein skimmer. I turned my skimmer back on after three days per the directions. I will leave it off for the duration for the second dose.
