Fungus Guard Tablets is rated 4.25 out of 5 by 4.
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.

I have a 20 gallon tank. I put 2 tablets into the tank. The box says to remove the carbon filter, but then I will have no filter. I have the Marineland Penguin 150. Should I just leave the carbon filter out since it has a biowheel too?

Asked by: katiemiro
Yes, you remove the carbon cartridge and leave it out. The bio wheel will continue the biological filtration. We recommend doing a partial water change prior to each dose of the medication to help remove what the carbon filter would have been removing for you.BREX

I have a 70gl. aquarium.I treated for ich 2days ago. Come to find out its not ich but a fungus. Can I add fungus medicine to the ich medicine treatment?

Asked by: Hankster67
If the ick medication is ours, yes. If not, no. You would then do a partial water change, add new carbon for a few hours, remove the carbon and treat with the Fungus Guard.BREX

Does anyone know what the percentage of Malachite Green and Formalin are in the Tetra Fungus Guard?  I'm thinking about treating my discus, but worry about the Formalin percentage.

Asked by: cross
It contains neither; it is Nitrofurazone and Potassium dichromate.BREX

I have a 5 gallon acrylic tank. I used have a tablet on Friday, today is Wednesday and my tank is still green even after a 25% water change. I have a API Superclean 10 filter that's less than 2 weeks old. Is my tank stained? Why is the water still green? 

Asked by: Bettagirl123
I am not familiar with the API filter, but if it contains carbon that is 2 weeks old, replace the carbon filter. A very faint greenish tint to the water may stay around for a week or so. Or you could have an algae bloom.BREX

Do I have to set up a hospital tank to use this as I have three other fish who do not seem to be affected.

Asked by: Crick
It is generally recommended to do so as meds can have some negative effects on tanks, but if the tank is in overall good condition due to regular water changes, proper stocking levels, etc, it should be okay to use. This product is not recommended for scaleless fish, snails, shrimp, etc.BREX

Is it safe to use with Lifeguard?  How long does one dose stay active for? How long does it take for the filter to clear out the green color and medication? Is it safe to put other healthy fish in the tank if it's been a few days and the water is still gr

Asked by: Bettagirl123
No, you should not mix it with LifeGuard. The coloration will stay until you are done treating, do a partial water change, and add fresh carbon to your filter. The filter should be left running with no carbon in it during treatment. One treatment lasts 4 days. If the fish are well by the 5th day, do the water change, replace the carbon, and it should pull out the color in a day or so. If they are still sick, do a water change, and second dose, leave the carbon out for 4 more days.No, don't add fish until all treatments are done, and you have had a chance to run carbon for a few days. You want to make sure everything is okay before adding new fish. I would also add Tetra Safestart Plus to boost your biological filter, after treating.BREX

How many fungus guard tabs to treat 100 gall aquarium and how often 

Asked by: codling
You need one for every 10 gallons of water so a total of 10 per treatment, unless you have a lot of gravel and décor. Gravel and décor will displace some water, so your tank would not actually be holding 100 gallons. It may only have 90 gallons of water in it, for example. In this example, you would only need 9 tablets. You treat for four days, and then if fish are not well, you would do a second dose on day 4.BREX

Hi guys, l am treating my oranda for swim bladder / dropsy with an Interpet product, l want to use Fungus Guard , 2 days ago was the lastdose of Interpet , when can l start with Fungus guard , please can you advise asap,Thankyou

Asked by: bowman1
Do a partial water change, and then begin treatment. You may also want to run fresh carbon for a few hours, but it is most likely unnecessary if you do the partial water change.BREX
