Bettas & Maracyn-Two & Fin Rot

Question
I have 8 separate 1 gal. bowls for my 8 bettas.  Two of my fish have developed fin rot.  I bought Maracyn-Two.  
1st question:  How do I adapt the Maracyn-Two medication instructions to apply to 1 gal. bowls?
2nd question:  Do I change the water every day for each day's application of medicine or simply add the medication to the same water during the full course of treatment?
Your expertise is greatly appreciated.  I do love my bettas.

Thanks.

Cassandra


Answer
Hi Cassandra,
I'm sorry to hear that.

One of the best things you can do to battle finrot in bettas is target the cause. Which is primarily dirty water. So yes, with your second question, it would definitely be good to change the water everyday and then re-dose the medication. :)

Dosage for 1gal bowl. (According to "Healthybetta.com" )


*Maracyn-Two
1 Gallon Dosage:
For one round, dissolve one tablet into 10 teaspoons of water. For first day, add 2 teaspoons of concentrated mixture per 1 gallon of water. For days 2-5, add 1 teaspoon of the concentrate per 1 gallon of water

*Maracyn
1 Gallon Dosage:
Do 100% water change. Dissolve 1 tablet in 10 teaspoons of water. Add 1 teaspoon of concentrate per gallon. Add 1 teaspoon daily of the concentrate mixture.

I really hope this helps and I hope your bettas become healthy and happy again! ;-)
