## Overview

Seachem ParaGuard 100ml is a premium aldehyde-based treatment designed to eliminate external fungal, bacterial, and viral lesions as well as parasites in both freshwater and marine fish. Its unique formula is fish and filter safe, free from formaldehyde and methanol, and ideal for hospital and quarantine tanks, making it a must-have for maintaining healthy, vibrant aquatic communities.

## Description

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).

Review: 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
Review: 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.

## Questions & Answers

**Q: I have 1 gallon fish tank, how do i use this product? do I need to do a water change after first dips?**
A: Seachem states:  For 1 hour dips, use 3 mL per 4 L (1 gallon*). Dips may be extended if fish show no evidence of stress. It says nothing about a water change.

**Q: Does this kill leeches and leech eggs? Will be used in quarantine buckets for plants and decorations, not the tank.**
A: Malachite green whish is active ingredient kills them so in theory yes it should  work. I've used it for hdras and flukes which both tend to be more hardy than leaches.

**Q: Will this cause ammonia spike? Or, kill any beneficial bacteria?**
A: I personally didn't have any problems. I used a half dosage twice a day and it worked well. I would use caution though with sensitive fish.

**Q: I have 37 gallon tank and how many times do i use to cure the ich?**
A: I used a capful for my 37 gallon tank and followed the instructions on the bottle for the amount of daily treatments.  Hope this helps.  It cleared my tank of ich and will take care of any parasites.  If you have shrimp. etc it might be too strong for them...I only had fish.
