ParaGuard is the only fish and filter safe aldehyde based (10% by weight) parasite control product available. Unlike highly toxic and difficult to use formalin based medications, ParaGuard contains no formaldehyde or methanol and will not alter pH. ParaGuard employs a proprietary, synergistic blend of aldehydes, malachite green, and fish protective polymers that effectively and efficiently eradicates many ectoparasites on fish (e.g. ich, etc.) and external fungal/bacterial/viral lesions (e.g., fin rot). It is particularly useful in hospital and receiving tanks for new fish and whenever new fish are introduced to a community tank. For use in freshwater or marine. ParaGuard is recommended for the treatment of certain diseases in marine and freshwater fish only. It IS NOT recommended for treating any style aquarium containing invertebrates, corals, crustaceans, or elasmobranchs (sharks and rays).

Paraguard is a+ quality trusted when it comes to the fins that matter
My fishes tolerate the blue dye from this solution extremely well. The chemical compound made within the product is very effective and keeping water quality to perfect accuracy in order to maintain zero nitrate and nitire levels. Combined with good filtration and maintenence, I can attest to this product being working in keeping my Oscars healthy both visibly and my brain mentally from any stress or concern my animals may have.

A must have for receiving Discus
So just to clear things up for anyone who is unsure. Paraguard & stress guard can be used together. I recently got back into discus and in knowing how sensitive they can be I wasn’t sure what to use during quarantine. I watched a couple of videos & did some reading & reviews on line & the paraguard was highly recommended. There wasn’t anyone using it with stress guard but I figured I’d give it a try. So here is how I used it. I ordered the first 7 discus & I didn’t do as much research on the seller as I should have (I won’t mention sellers name but just believe cheaper is NOT the way to go) anyway when I got them they were skinny, doing a whole lot of rubbing and 2 had ich. That being said I turned the heat up to 92°(this high for fish who can handle high temp only) & treated with both stress guard & paraguard for 2 weeks (put temp slowly back down to 84° when done).All fish survived & are doing great. Now as for the second batch of 9 discus . They came in healthy (more reputable seller) so I did just 3 days of both. Now if you are doing a 2 week quarantine like you should if you see any trouble you can restart both until you see they are doing better (2 weeks if sick is best). Make sure you remove carbon from filter when using paraguard. If your using stress guard alone for injury you do not need to remove carbon. I hope this helps . I highly recommend both products

Saved my betta
Saved my betta! I got my boy some top quality food which made him super sick. I thought he was a goner. Used this in combination with an antibiotic and he survived his stressful ordeal.

So happy this didnât harm my fish
I purchased this early October because I noticed that my Betta was looking fuzzy, she was staying on one side of the bowl, and wasnât eating. I read one of the reviews saying it killed their fish, so I was hesitant, but decided to give it a try. I wasnât sure how much to pour, so I poured a cap full and watched her throughout the day.
The next day she seemed a lot more lively. When I cleaned out her bowl again, I poured in a cap full again. After using it about three time, I noticed the fuzziness went away completely. She seems a lot happier and sheâs eating again.

Works fairly well but….
I am an old woman.. I’ll admit that freely.
I am in good health, and the strength in my arms and hands is fine.
There are leaders of several countries that are easier to gain access to than this bottle is to open.
Press down and turn, it sounds simple, and we’ve all done it hundreds of times.
After trying to open it, I got out my handy dandy little tool kit and tried to open it with a set of pliers.
Nope, I then talked to God for a few minutes, explaining that he needed to keep me from dropping this into the center of I65.
I sat it in front of my aquarium and hoped the fish would see the medicine and feel better, knowing I had made an effort.
I thought briefly about stabbing the bottle and squeezing it out.
I think that is called assault, however.
Finally, the UPS guy drove up, and I accosted him (that wasn’t necessary, but he was a fine example of God’s best efforts, and I couldn’t help myself).
He easily opened it, but his arms were the size of my waist.
Might want to work on that for us, just plain old mortals.

Excellent for Betta fish
My fish had tail rot and was not eating. After using Paraguard for about 2 weeks, my Bettaâs fin tail began to grow back and he started eating again.

It killed 8 of my fishes overnight. Itâs too dangerous. Do not use.

Balık ve diÄer tank canlıları için güvenilir olup sadece ich paraziti olmamakla birlikte genel kullanım amaçlı bir üründür. Ana etken maddesi malahit yeÅilidir. Karantina tankına gerek yok, mevcut ana tankınızda kullanabilirsiniz. Zaten beyaz benek gibi bir paraziti ayrı tedavi etmek pek mümkün deÄil. Tanktaki tüm balıklara, objelere vs mutlaka bulaÅmıÅtır. Bakterileri öldürüyor mu diye merak edenler var ise yanıt vereyim. OturmuÅ bir akvaryumdaki bakteri kolonisini yok edemez. En fazla bakterileri seyreltir. Su deÄiÅimlerinde su düzenleyici (prime gibi) ve ardından 1-2 saat sonra bakteri kültürü (stability gibi) dozlayabilirsiniz. Malahit yeÅili ne için kullanılırsa bu üründe o kadar geniÅ tedavi rolüne sahiptir. Seachem firmasıda bunu doÄruluyor. Tedavi sürecinde filtreleri kapatmanıza gerek yok. Aksine ek hava taÅı vs ekleyerek bol havalandırmayı amaçlayınız. Kısmi su deÄiÅimi üstte yazdıÄım gibi pek tabii yapilabilir. Sadece filtre sepetinizin içinden mutlaka purigen, karbon vb medyaları çıkarınız.
