Chem-Marin Stop Parasite Information

Product Manuals & Documentation

Chem-Marin`s Stop Parasite helps to control parasites such as Oodinium and Cryptocaryon in a marine aquarium that contains corals or invertebrates. Stop Parasite is made from many different agents. One speeds up the fishes natural slime coat, causing the parasites to detach themselves. Another attracts parasites as a non-nutritional food source. Others speed up appetite and build the immune system. It will not harm the internal organs of the fish. 8 oz.

Recommeded Purchase Size (for a 5-day treatement):

8oz. for 30-55 gallons
16oz. for 75-100 gallons
32oz. for 125-300 gallons

During the treatment cycle, eliminate all filtration which removes particles smaller than 25 microns. Stop the use of poly filters, Chemisorb, charcoal, UV and ozone systems. Protein skimmers may be left running.

Put 10 drops per gallon of water twice daily (once in the morning, once in the evening) into the tank for 5 days. Stop Parasites is acidic, so check the pH of the tank both before and after each dose and buffer if necessary.

New fish:
When you bring new fish home, add 5 drops of Stop Parasites to the water in the acclimation container. When buying new fish, ask the store clerk to add 5 drops of Stop Parasites to the water in the fish bag.

Add 5 drops of Stop Parasites to the tank water twice daily for 4-5 days after new fish are introduced to prevent stress induced parasites in the new fish as well as the old ones.

Did not work for Marine Ich

Reviewers Rating Unsatisfactory

Experience Level: Expert

Comments: Despite numerous products on the market for 'reef safe' marine ich treatment, none have worked for the marine ich that my tangs have. This one also affected a torch coral and open brain coral--one died and the other nearly died. Other corals, clams, and inverts that I have did not seem affected. Despite following the instructions, my tangs developed new waves of ich infestation during >2 weeks of treatment with this product.

Comments: Didn't expect this to eradicate all parasites from my tank, but hoped it would help my fish to fight them. After ceasing all filtration except some skimming, I dosed per directions. After the 5 day treatment there was no improvement. I'll have to remove the fish to quarantine and fallow the tank for 8-10 weeks.

Comments: I used this in my reef tank as directed to prevent the loss of all my fish when I had an outbreak of ich. I did not lose any fish, nor did I lose any corals nor my clam. They weren't happy, but they all survived the treatment. I don't think that the product is "snake oil", but I do think that it gave my fish the strength to resist the parasite long enough until it died. Finally a reef safe product to deal with ich.

Comments: Purchased Stop Parasite after having a random (minor) outbreak of Ich in my 200 gallon reef tank. A long story short after using the product to the letter my tank went from a minor outbreak to terrible on day 4 of treatment and 3 days after that all my fish but one were dead. Fish included Desjardini Sailfin Tang, Clown fish, Powder Blue Tang etc... This was a long shot in my book, one that I highly recommend you avoid at all cost. Quarantine your fish with hypo or copper. My one surviving fish and a couple replacments are doing great in a qt tank with copper.

Comments: This is one of the worse products we have ever used. We added six new fish to our 125 gallon tank. We immediately realized that we now had ich in the tank. Tried this product! Every fish that was new, died. Did the last burial according to Bill Cosby (ck. out first episode!). We will go back to our other product -- Ich Attack!

It really worked

Comments: I was skeptical after reading the reviews here, but I had become desperate for an ich remedy after losing a few fish. I was suprised how well this worked -- if I didn't know me, I'd think this was marketing BS. Within a day, I noticed fewer spots on my powder brown tang, and by day 3 it was all clear. I continued the full 5 day treatment and monitored pH. I think the people who are complaining neglect the pH. If the pH drops, the fish will suffer even further stress. I use kalkwasser top off and still had to add some buffer around day 3.

Comments: Chem-marins stop parasites does help control saltwater ich. Ive used it several times in my various reef tanks and never had any problems. It didnt affect my corals or inverts and it starts working pretty quick. I always keep some on hand. Just make sure you buffer your PH .
