Rated 5 out of 5 by from worked quick I added a piece of drift wood to my aquarium and fungus started growing on it and then I noticed one of my angel fish had the same growth on it.The fish stopped eating and was lethargic.So I ran up to the pet store and picked up some Beta Fungus Guard and in less that 12 hr.the fungus was off the fish and it was eating.I pulled out the drift wood and boiled it in water to kill the fungus on the wood.

Rated 4 out of 5 by from Minimal Instructions I placed the tablet in my 10 gallon tank and it seems to be working quite quickly! And for that I am happy! But the box comes with little instruction as to how many tablets and how many times to put one in the tank. I don't want to hurt my fish and I also don't know if I need to remove the filter because its a 10 gallon tank. It stated if it was a 40 gallon to take the filter out and change the water but not sure if it applies to my 10 gallon. Other than that it looks to be working but I don't know if Im doing it right : (

Rated 4 out of 5 by from Good Product I recently purchased a Orange and Black Oranda goldfish. Within 2 weeks, I noticed white fuzzy patches on his black. After some research I quickly ran down to my local fish supply store and purchased the Tetra Fungus Guard. As soon as I returned home, I put one tablet in my tank. Problem got better with in a couple of days.Only downfall is lack of instructions on package. Doesn't talk about how long filter needs to be out.

Rated 5 out of 5 by from Works good I had an unknown (to me) problem with my platy fish dying off, with what appeared to be no symptoms. Used Fungus Guard and the problem has not continued. Will gladly use again if this condition reappears.My only problem was with the limited directions, does not say how long to keep up treatment with the filter pad removed and when to begin the water changes. Only talks about if a second treatment is required.

If I started treating the tank for fungus and then something came up and on the 5th day I will not be home to do a second dose, is it better to do the second dose on the 4th day or the 6th day?

Asked by: ELMA
We would recommend doing it on the 4th day. Just do a small partial water change first, to keep your water quality up, and then re-dose. BREX

Can I use fungus guard and Ick guard at the same time in a 10 gallon tank? Initially I thought it was Ick but upon further inspection I think it's fungus. I already added the Ick guard but I want to treat the fungus before my Molly dies.

Asked by: AnnaM
Yes, you can use those two medications simultaneously. I would recommend a small partial water change prior to dosing, just to keep up with your water quality. Otherwise, it should be fine. BREX

How often to treat a large osar w fin rot

Asked by: Shakur
Thank you for inquiring about this Tetra product. Treat the tank once every four days. If the fish are not 100% better by the 8th day, you should perform a partial water change, and switch medications, as you may not have picked the proper one for the issue the tank is experiencing. BREX

Can this product be used with live plants?

Asked by: Garrett
Thank you for your interest in this Tetra product. It is not recommended for live plants, no. They will seem to be okay initially, but may lose some leaves over a period of time after the treatment is completed. BREX

Can I use tetra fungus guard and melafix at the same time?

Asked by: Tygerlili311
We appreciate your asking about this prior to actually dosing the tank! You definitely do not want to mix meds from different manufacturers. Use one or the other first, and if it is not effective, or if you have two different issues going on, then treat with the second one, after you are finished with the first treatment. And be sure to do lots of small, partial water changes to stay on top of your water quality. At the end of all treatments, add SafeStart Plus to boost your biological filter. BREX

I am currently using Tetra Fungus Guard tabs to treat my discus for a bacteria infection.  I want to turn on my UV sterilizer to kill the bacteria in the water.  Will the UV ruin this medication? I can't find anything about UV sterilizer w/ nitrofurazone 

Asked by: John_
Thank you for your interest in our product! In general, UV sterilizers have more effect on medications that are used for parasitic control, such as chelated copper. It should not affect Fungus Guard. BREX
