New discus showing symptoms of sickness...any thoughts?

Pat,
I used 2 packets (1 pack/10 gal). Then I did another treatment 24 hrs later per the box. I’ve been checking to see if water parameters changed but they have not yet.

Did you do a water change before redosing Alex?

Pat,

No I did not. Usually I would have but I decided to follow to the point. Do you think it overdosed him? The others are doing quite well.

That is my concern Alex. It sounds like an overdose. I would suggest doing a 50% water change and redose for the volume of water in the tank.

I agree! But, since you may have over dosed them by not doing a water change to begin with, I would only treat for the water being replaced.

All,

Thanks for the help. Unfortunately Tiger continues his erratic swimming and ultimately hit the tank sides hard and passed. I went ahead and did the WC and redosed the Furan to match the tank size.

I’m still somewhat confused though as to the dosing as the box says to redose without a WC after 24 hours—maybe a mistake on the box? Or maybe something else going on...

All the others are doing/looking well and eating.

I’ll continue to update if things change.

Thanks everyone; I’m glad that I at least got Blue back on the road to recovery.

Alex, I'm sorry this happened. I've never heard anyone reporting an issue like this when using Furan 2, but by your description it does sound like an OD. Your little blue one seems to be the most sick, so I'm surprised it didn't have a reaction instead of the other one.

I've looked at several other posts from around the internet and it seems you are dosing correctly according to API's instructions, but if you notice similar behavior I would probably discontinue the med.

I would also recommend doing 50% water changes between treatments regardless of what the instructions say...

And to correct my earlier statement, they say Furan 2 will not hurt biofiltration...

Brian,

Yeah after this experience I will definitely do WC between treatments regardless of instructions. I was expecting to lose one, but he was the least likely out of the bunch to go I thought...

Furan’s treatment cycle is complete now, so I will let them rest from meds and continue daily 50% WC. Hopefully the remaining fish will continue their current activity levels and will continue to recover (and hopefully grow).
