Review of Seachem Paraguard

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.


In the aquarium, use 5 mL (1 capful) to every 40 L (10 gallons*). Repeat daily as required as long as fish show no stress. For 1 hour dips, use 3 mL per 4 L (1 gallon*). Dips may be extended if fish show no evidence of stress.

Yes I know it's broad spectrum and not specific to one particular disease, but I thought i would give it a go. My fish have Ich at the moment, which didn't show up untill about 1 week after the introduction of the Gold Severums and only they have it, so I orderd Saechem Paraguard, as it it supposed to be safe for most types of fish.

Day 1. 20.8.13 12:30pm, I did a 150lt water change "400lt Tank", tempurature up from 25c to 28c then added 40ml medication the water did not turn blue or green, at 5pm no visible signs of stress on the fish, especially Sir.P my Sailfin Pleco.

Day 2. 8:am the fish are still showing no signs of stress and fewer white spots on the Severums, although I did loose 1 Severum. 2:pm another dose, still no signs of stress, Sir.P is still chasing every one around, 5:pm still no signs of stress and all are still eating, a good sign.

Day 3. 8:am still not showing any signs of stress and only a few white spots remain on the smallest Severum. 2:pm another dose, the fish still show no signs of stress and swimming around quite happy, 5:pm all good.

Day 4. 8:am no white spot to be seen at all. 2:pm this will be the last dose as per directions, I will take the temprature back to 25c slowly over the next week.

Day 5. 25.8.13 8:am everything back to normal, 1:pm 100lt water change, that looks better, crystal clean water, 5:pm and the fish are starving again.

During the treatment I also did water testing 1 hour before and 3 hours after dosing the tank. I used API test kits.

PH: 7.2 before and after

Ammonia: 0ppm before and after

Nitrite: 0ppm before and after

Nitrate: 5ppm before and after

As you can see the medication did not alter the water chemestiry so in my case it did as stated.

Yes it is my own fault for not quarantining the fish first, in my defence I didn't have a spare tank and I did drip acclimate them for 2 hours before introducing them into the tank, still there is no excuse not to have a Quarantine or Hospital tank handy.

So I guess I caught it early enough as not to cause any kind of disaster in the tank, I did loose 1 Severum, but they are very small, all in all, with all the orders i've placed with Livefish, this is the only one i've had problems with.

Would I recommend Seachem Paraguard,in my case yes, it worked and worked well, with no obvious signs of the Pleco being stressed what so ever, I continued with the full strength doses for the course of the treatment, but as with everything use at your own discretion.

I would definatly use this product again if ever needed.

If this review helps anyone in some small way then I'm pleased.

This is it.

Sometimes when I reflect back on all the beer I drink I feel ashamed. Then I look into the glass and think about the workers in the brewery and all of their hopes & dreams.
