formalin bath info needed

[kenith]

I have read the post below and gathered what info I could about formalin baths, though I still have questions about the correct dosage and frequency of formalin baths for brook. There seems to be a wide opinion on instructions to do so. The fishes are in a 20 gallon qt tank undergoing tank transfer method.

- Can someone confirm 1.1ml per gallon of water will yield a 200-250ppm solution?

- Does the dips actually need to be done on days 1, 2, 3, 5, 7 & 11?

Are you prophylactically treating for Brook?

No, I had a brook outbreak. The surviving fish appear fine and eating well.

I will be treating in the future prophylactically for brook on new fishes.

By my math you need:

0.676 ml Formalin 37% per liter to get 250 ppm
2.558 ml Formalin 37% per US gallon to get 250 ppm

0.541 ml ml Formalin 37% per liter to get 200 ppm
2.046 ml Formalin 37% per US gallon to get 200 ppm

Thanks. Thoughts on how many baths and if the schedule is necessary?

I am in the same boat with my clowns. I am leaning towards administering long-terms baths for 5 days with 30% daily water changes before each dose instead of doing formalin dips.

I did my first formalin dip a few days ago, so I'm by no means giving advice; but only sharing my experience...... I found the dip extremely easy and not very stressful on the fish, in fact my foxface ate moments after the dip. I'm not sure how effective it was, because now I believe brook was not present.

1 gal dt water, 1.25 ml or 20 drops Fishvet Formalin MS for 50 mins, with airbubbler for o2....blenny did great too!!!!

That's what I do for preventive dips on new fish. It gets you roughly 125 ppm which is about the upper limit for scaleless fish like blennies.

With a known active infection on other than scaleless fish I would probably go up to 200 ppm for 30 to 45 minutes and do daily dips.

For preventive dips it should be enough to do the dips when doing the TTM transfers.

tagging along, I have 2 fish (Redfin Wasp + Flame Hawk) that survived what MAY have been a brook outbreak that wiped out all my other fish. The 2 survivors are in QT and the DT is fallow. I am not sure if I NEED to treat these two but I think I am going to before returning them back to the DT after the 72 days.... I am going to TTM them back to the DT and maybe do the formalin along the way...

I'll keep updating this post to help, but you'll definitely want to treat for whatever disease wiped them out. ttm with prazipro at least. If you think it's brook, you'll need to decide which treatment will work better for you.

Hi ThRoewer,

Are the calculations above for a dip, and for how long should i keep my fish in the Formalin for?

Thanks
