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.

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

Not sure if this is a fungus but fish did turn white & died. Water is ph 7.2' ammonia 0 nitrite 0 nitrate about 50. I just purchase 3 clown loaches . This problem started.. my question is should I use fungus guard or life guard.

Asked by: Johnny 101a
Thank you for your inquiry. The first thing to do is a partial water change with a good vacuuming. Your nitrates are high and indicating that the overall water quality is not good, even though the other parameters are fine. You want to get those down. Secondly, you can't use either medication with clown loaches. Clown loaches tend to be very sensitive to medications. If you do not have any other fish showing signs of illness, I would not use any medication at this time. And if you are, I would set up a quarantine tank to treat the fish separately from the loaches. If the loaches are not presenting signs of illness, they are not necessarily the cause, although they could be. It could also be that adding more fish to what appears to be an unbalanced or overloaded system caused the issue. I say this because of the high nitrate reading. You want those nitrates down to less than 20 ppm.BREX

I have a 5 gallon tank, and the fungus, not sure the diagnosis, seems to only be affecting one fish. I feel like I should treat my whole tank (only consisting of two platies and two mollies), so should I cut one tablet in half?

Asked by: tanked
Thank you for your question. Since it is only affecting one fish, try a partial water change first, with some AquaSafe Plus to see if the fish can heal without meds. If that does not improve the fish, then yes, half a tablet. You might check your pH and hardness too. These type of fish do not do well if the water is soft or the pH low. They have to have very hard water. They also need vegetable matter in their diet (especially mollies).BREX

My butterfly betta, 'beast', has tail rot. I've tried kordon rapid cure, aquarium salt, and melafix he still has it. The blood gone but tail still looks awful. What can I do? Please help

Asked by: stacya3149
First, make sure his environment is proper for him. He needs a tank between 2 and 5 gallons in size, and his water should be clean, and heated to between 76 and 84 degrees. He prefers to be very warm. Second, the tail looking awful does not mean that he still has the disease, it may mean he just needs to grow his tail back, and that will take time. You can speed that along by doing small, frequent partial water changes, heating his water, and dosing his tank daily with something like AquaSafe Plus. If the tail has any blood or the edges are very white instead of sort of opaque white, then treat with the Fungus Guard for four days. Remove your carbon, keep the filter operating. On day 5, do a partial water change, and replace the carbon.BREX
