Brownish spotting after Formalin Treatment

[Tuffloud1]

I finally caught all my fish and moved from DT to QT after an outbreak that killed 3 of my fish so far. Symptoms were white spots, deteriorating fins, white veil of death, muted coloring, rapid breathing.

I began treatment with the pictured product which contains Formalin and Acriflavine. I am following instructions.

After 3 days of medications and constant water changes (per instructions), my yellow tang looks like he is "stained" the same color as the product.

He appears to be breathing rapidly and stopped eating. The clown I have "looks" perfectly fine however he stopped eating as well which is very unusual for him.

I did a 25 percent water change immediately when I noticed this morning and started running carbon to get this crap out of the water. The water is now crystal clear.

What is going on? Anyone know why he has the splotches or what this means?

Here is what I used.

Looks like bacterial infection to me.

It's hard to believe it is a bacterial infection. He was one of the fish that appeared flawless. However 3 days into using this product he now looks like this and stopped eating. Not only that, but this med is supposed to help with bacterial infections.

What do you recommend I do?

Was this to treat the ich, velvet and flukes you said you had in another thread? What dosage did you use?
I think those red markings are more than likely burns from the formalin. I've used that brand of formalin before and it was really hard on the fish. I just did a dip on him and I really didn't think he was going to make it through the night.

He was dead this morning. This was to treat velvet or brook, I have no way of knowing what exactly infected my DT, and I did everything I could to save my fish.

I used 2 capfuls in 20 gallons and did 25 percent water changes daily with replenishing the amount of med taken out (per instructions).

I have now lost every fish in my DT except my pink spotted goby and oscillaris clown.

I am really ticked off because the yellow tang was the healthiest out of them all and I believe strongly that this "Marine-Aid" killed him.

Yeah, I can't say I blame you. Where did you get the dosage of 2 capfuls? Because formalin is so strong I do dips rather than baths. Formalin can be an effective treatment but I typically lower the dosage or length of contact.

1 cap per 10 gallons is right in the instructions. I took a picture of the bottle in the second post.

I'm really getting discouraged on this quarantine business.

Where do I go from here? Since I have no idea whether or not the "marine-aid" killed the parasites that it was supposed to target (it killed my fish), should I drain my tank and allow to dry and start from scratch?

I have an aqua clear filter going on the QT, do I need to start over with that? How do I know if my QT isn't infected with parasites?

Believe me i understand! I went nearly a year of fighting flukes, brook, and velvet. Very frustrating and I nearly got out of the hobby.
I would definitely drain and sterilize everything associated with the QT. Do you have a quarantine protocol?

Drain and sterilize!!???

It was my understanding that going FOWLR for 13 weeks would knock out any fish parasite.

I am setting up my QT from scratch since all my fish are now dead and cycling it fresh without anything from the DT and allowing the DT to sit for 13 weeks with only corals, shrimps, crabs and snails.

 

[Tuffloud1]

Ah, drain and sterilize the QT, not the DT, never mind.
