Fluconozol after effects

[PJNANO]

A couple of years ago I had a serious Bryopsis/GHA outbreak in my BC29 and treated with Fluconozol. The treatment was a success. Sadly though, it is coming back. I thought I was controlling it with a 3 day lights out and diminished feeding and less intense lighting schedule but it's still there. As I am in the process of trying to upgrade this tank and moving almost everything over to a new system, I have a couple of concerns.

1. I don't want to transfer these same old problems to a new tank

2. I don't want to transfer semi toxic medications to a new tank...let me explain

As I was thinking about all the things I want for my new system, one of them being a sump with Refugium, It occurred to me that I use to be able to grow Chaeto like crazy in the back chamber of my BC29. I removed it all when I did the Floco treatment and never replaced it until fairly recently.What use to grow like a weed, now won't grow at all. So I'm wondering if there is residual Fluconozol still in the system. Was thinking of doing another treatment, but now I'm not so sure. Any thoughts?

Most of it would’ve been removed via water changes or carbon. It will also biodegrade over time. A residue is always possible but unlikely in a significant concentration.

Personally, I don’t think it’s the right solution to the algae problem unless the tank is being completely overrun and you need to buy time to try other things.

I'm inclined to agree with you at this stage of my reefing, but I am concerned about transferring to a new tank and I really can't remount a bunch of Zoanthids to a clean rock, which is where the algae seems to be concentrating the most.

I would think if there was enough fluconazole in your system to prevent chaeto growth then there would be enough to prevent the GHA from coming back. The fact that you’re getting some GHA returning makes it doubtful that fluconazole is the reason your chaeto won’t grow.

Good point
