Rated 5 out of 5 by from Saved My Bettas Life! On Wednesday morning I noticed that my Betta was covered in fungus and his eye was very strange looking. I bought the meds and at like 9pm I used half a tablet (2.5 gallon tank) to treat his tank. By the next afternoon I could tell he was getting better. And by this morning he is doing very well. I have only used 2 doses so far! :)

Rated 5 out of 5 by from Great product, worked like a charm! Ok, so the key to this treatment is definitely get it going early. I had a black moor starting to get covered in white spots from ick and totally lethargic and began the treatment, by the morning of day 3, the spots were disappearing and my fish was VERY active! I was sooo excited to see the black moor doing so well, especially since it was my 6 year old son's favorite fish, that i HAD to write a review. This product worked great for me for ick, but it definitely, in my opinion, depends on how early you get it going, i had a 2nd goldfish quarantined with ick, much further along that did NOT make it, but his ick was SO much more progressed. However, ALL the fish in my big tank where i did the treatment pulled through great, composed of fancy goldfish and baby guppies! Thanks Tetra!

Can be used Ammonia safe on 2-3 day after start treatment? Because Ammonia level is go up quickly , looks like Lifeguard kills Aquarium good bacteria and biological filter stopped working.

Asked by: bsk68
All medications will affect the biological filter to some degree or other. In general, you will not have an issue or get a spike, unless the overall balance of the tank is not good. We typically recommend a small partial water change prior to each dose of medication to keep the water quality at a good level. If you have not been doing these, then I would definitely recommend one before your next dose.BREX

How many Tabs?

Box says 1 tab a day for every 5 gallons. I have a 10 gallon tank exactly. Should I use two tabs (1 for every 5 gallons) ? My pleco caught ick and she's just a baby, it is getting to her really fast. She has a tankmate - a betta. Both are very young.
Asked by: BettaMommy
First day I made mistake and didn't calculate exact water amount in thank, so you have to calculate and use as directed, not all tank that said 10 gallons has a ten gallons. Also as BREX said gravel if you have a gravel displace some water.

What more can I do? my goldfish has Ich. - new tank and new fish

I got my oranda goldfish a week and a half ago. I am cycling a new tank and started the tank with Quick Start a week before I got the fish. I have a 10 gallon tank but plan to upgrade in 6 months. I noticed the fish flashing and rubbing gravel and plants from the moment she was in the tank. The fish did not have any spots on it and was eating and very active. I waited four days thinking it was the cycling of the tank. On day four I treated the tank with " Copper Power Green" thinking it could still be Ich but not seeing any spots yet. Five days later my fish started having a white spot on her Wen. I did a 15% water change and added more water conditioner and quick start. The next morning the fish had a second spot and is still flashing. I started the " Lifeguard all in one". I am on day three of treatment and the fish now has three spots on the Wen. Is there anything else I can do? Does it hurt the fish having both the Lifeguard and the earlier treatment of "Copper Power Green" in the tank? Have I lost the progress I have made on cycling the new tank? I still have ammonia spiking to 3 ppm, nitrate and nitrite are low. If I use the QuickStart will that nutralize the Lifeguard? Thank you for the help. The fish is still eating and active but symptoms have not improved.
Asked by: Goldie19
Flashing is not due to ick, it is usually due to other parasites, especially flukes. Yes, mixing the two meds could have set the cycle back a bit. I would recommend daily partial water changes of 2 gallons for now to help reduce the ammonia.I would also add 2 tablespoons of aquarium salt to the tank as well to help prevent nitrite issues, kill parasites, and reduce stress on the fish.It is not a good idea to mix meds. Always do a partial water change, add fresh carbon to the filter and run it for at least 12 hours, then pull it and start the new medication.I do not know what the spots are, but they don't sound like ick. They have not spread like ick typically does. I would recommend Parasite Guard to kill the flukes and whatever these spots are; it will be a bit stronger and more directed at the issue.Once the fish is well, do one last partial water change, and add Tetra Safe Start Plus to help with the cycle.BREX

Should I use Lifeguard with water conditioner or straight in tap water?

I'm wondering if I should add water conditioner to the tank where I'm putting the Tetra Lifeguard treatment.Also, can the fish go in the treated water right away or should I wait for the tablet to dissolve completely? Thanks!
Asked by: Matt3o81
Wait for the tablet to dissolve all the way. If you have changed any water you should definitely use water conditioner. Additionally, it is a good idea to change the water, prior to dosing if you did not do so. Water conditioner can remove chlorine and chloramines from the new water, but it will also reduce stress on the fish.BREX

Pest snail death and Lifeguard

QT Tank, has a pest snail or two (literally, that I can see). It is okay that they cannot survive with Lifeguard, can I do any partial water changes during fish treatment to vacuum out the dead snails during the 5 days?
Asked by: PWTX
Yes, you can do a small water change, like 10%, prior to each dose to keep water quality up and to remove the snails. In fact, we encourage this during medicating.BREX

Can I use Lifeguard with Spotted Raphael Catfish ?

Asked by: HarleyK
This catfish is scaleless, and medication should be used very carefully. I would recommend trying a half dose. If the catfish reacts, put a de-chlorinating product in the water immediately.BREX

I have been treating my guppies who have tail rot with Triple Sulfa for 3 days. May i use lifeguard in addition to the antibiotic?

Asked by: Buzzor
You would need to do a partial water change, replace the carbon in the filter and let the tank run for about 24 hours prior to starting to dose with Lifeguard. Do not dose the two at the same time.BREX
