Review: Love this ❤️ - Been using this for my aquarium 👍🏼
Review: Works well for pop eye - My Blue Beta fish recently had a pop eye infection in 1 eye, she seemed like she would die anytime, very lethargic, enlarged gills, floating sideways on the surface of the tank and not eating anything. I searched about pop eye on the internet and found Melafix, ordered it and used it for a week. I put my Beta in a separate tank and dosed her for 1 week, everyday changing 70% water. After 1 week sbe still had her fins showing some fungus so I co tinued the dose for 3 days more. Now she is absolutely fine and swimming around the tank tormenting other little fishes like before.😂

## Questions & Answers

**Q: How to use for a 3 gallon tank for one fish?**
A: I use Melafix  when I am cleaning the pond.  I take out 25 % water then add fresh water, then add the appropriate amount of melafix.  It helps the fish adapt to the new water.  Also helps heal any sores they might have.  They seem to really like it.  I also put in the appropriate amount of salt for them as well. Hope this helps.

**Q: Is this safe for mystery snails?**
A: The bottle does not say that it will hurt snails. It has warnings for other things. However, we have not tried it in the bowl with the mystery snails.

**Q: Does it realy work?**
A: it depends what the problem is, you are having. as if per advise on the bottle, it works for all these, and pumafix does also. these, or one takes care of some bacterial issues also. you can try on bacterial and if it does not improve move to an antibiotic, best from  thomas labs on the net. these are good products and do help many situations. good luck with yours, my advise to you is what i do what these.

**Q: Mi pecera coge 3 galones gue cantidad debería usar ??**
A: Dosing for a 3gallons with Melafix (5ml for 10gallons) would be 1.5mls or 30drops.
