Happy Healthy Fish
Seachem ParaGuard is a fantastic product! I’ve been using it for my African cichlids, and it has worked wonders in keeping them healthy and free from parasites. It effectively eradicates ectoparasites, fungal, bacterial, and even viral issues without harming the fish or stressing them out. I appreciate that it’s a safer alternative to formalin while still being highly effective. Plus, it’s versatile and works well in both freshwater and marine setups. I’ve seen a noticeable improvement in my cichlids' health and behavior since using it. This is now a staple in my aquarium care routine. Highly recommended!

If u suspect parasites in your aquarium, try Paraguard BEFORE strong medications
ParaGuard is an awesome aid for any fish enthusiast. I like how it can be used in the entire tank (no hospital/quarantine tanks), that it dissipates after a couple of days (requires daily additions until problems resolve), because it wont interfere with your filter media in canister or other filters, AND because it's not a strong antibiotic thatd potentially harm other fish that arent sick. SeaChems medications such as Kanaplex or Metroplex are very good medications to use AFTER 50% water changes higher temperature or Epsom Salts, or ParaGuard seem to not be as effective 1st few days. Can be added into food for easier absorption as well or in water column to reach gills. If fish seem very sick, then these medications are the ones to use in a hospital/quarantine tank if wanting to avoid treating entire tank. All of SeaChem products are legit (I wish they paid me lol) as I've used them for well over 10yrs. Started off with Prime, the ONLY water conditioner aquarisuts should honestly use, GarlicGuard food supplement is extremely effective and keeps fish immunity elevated throughout life, ParaGuard for the reasons mentioned above, etc. If I had 1 brand to use for my fish, u bet its SeaChem. The good customer service is also an added bonus :) Lastly folks, feed your fish SOAKED FISH FOOD in water or Garlic Guard (soften pellets, absolutely NO HARD FOOD!) along with some peas ONCE A WEEK to avoid any SWIMBLADDER ISSUES as this event is bad for a fish that cant orient itself. Pea fiber will flush out their bladders and preventing this EASILY PREVENTABLE illness. This along with weekly 50% water changes should prevent roughly 75% of potential problems. Other 25% remains in how many fish are stocked, if all fish are compatible, etc as there are many variable to consider in aquariums inclusive of water source... that's where my Prime comes in hehe :)

Great for ick and fin rot - but usually takes 3 days to work
I get most of my fish through mail order. By the time they get to me they are often starting to show symptoms of any disease they've EVER been exposed to. This helps. I have successfully treated fish with ich, fin rot and body fungus. You do need to keep the treatments up, though - just putting in a dose for one day won't be enough. The directions are to use one capful for every 10 gallons daily. "Repeat as long as required as long as fish show no signs of stress." You can also use this as a preventative dip for new fish (which I highly, HIGHLY recommend) by putting half a capful per gallon of the dip. The good news is that not only do you not have to take the charcoal out of your filter and you do not have to worry about snails or shrimp, either. I did a heavy series of doses on one tank that had cherry shrimp in it, and not one died or even looked sick. If you keep fish, you really need to have medications on hand to treat them when something breaks out. Early treatment is key. I keep this and maracyn 2 on hand so I can nip diseases in the bud. Prazipro has a good reputation, too, but I have not tried that. Maybe there is a better broad spectrum treatment available than ParaGuard, but I have not found it yet. I would definitely like to hear people's feedback if they've found something that works better. By the way, this is what the bottle says: "ParaGuard is the only fish and filter safe aldehyde based (10% by weight) parasite control product available... contains no formaldehyde or methanol and will not alter pH... employs a blend of aldehydes, malachite green and fish protective polymers... effectively eradicates many ectoparasites (ich, etc) and external fungal/bacterial/viral lesions (eg, fin rot)."

This is a very nice medicament. I like that you must put some of it every day and doesn't modify the appearance of the water. It is the only one that had really solved a problem until now. It solved the ICH (white spots) in just few days.

Paraguard is a must have product if you're looking for a good medicine to cure most of the fish diseases. I'm using it in a Cichlid community tank consists of African Cichlids and they're free from ich and other diseases. After using the product for a week, they became lively and showed the signs of recovery. Please note that you need to pour exact amount of the medicine to your aquarium according to the directions as wrong amount of medicine can also be lethal to fishes.
