How does No-ICH work?

No-ICH disrupts the life cycle of the Cryptocaryon irritans parasite during the critical free swimming stage while having no effect on the health of your marine fish, corals, invertebrates, live rock, macro algaes or nitrifying bacterial colonies.

What is the life cycle of this parasite?

The life cycle of Cryptocaryon can be conveniently divided into four basic stages. Susceptible marine fish become infected with the active free-swimming stage, called the tomite.

The free swimming tomite has less than 12 hours to find and invade a host fish otherwise it will exhaust its energy reserves and die.

If an invasion is successful, the tomite penetrates below the skin and transforms into the parasitic stage which is known as a trophont. The trophont actively feeds on the fish's tissues, twisting and rotating as it does so. It grows rapidly, doubling in size approximately every 24 hours. By 48 hours, the parasitic trophont is just visible to the naked eye, appearing as a small white spot on the fish. By the third or fourth day of infection, the trophont has attained 3 to 5 millimeters in length and about this time it exits from the fish and drops down to the substrate. 

Within a few hours the trophont has firmly attached to the substrate, forming a thick walled cyst. The cyst, known as a tomont, is the reproductive stage which will eventually give rise to between 100 and 300 infective tomites, thereby completing the life cycle.

Of course, not all tomites are successful in locating and infecting a host, even under ideal conditions only about 5 - 10% succeed. Nevertheless, within a closed environment, Cryptocaryon can increase in numbers by approximately tenfold every six to eight days. This enormous reproductive potential explains the sometimes rapid build-up of infection levels in any closed system.

Can No-ICH be used with other products in the aquarium?

No-ICH can be used with phosphate and/or ammonia absorbents, but you will need to remove carbon from your filtration system as well as turning of your protein skimmer. Either of these will remove No-ICH from your aquarium before it can help. We also recommend not using antibiotics or other medications when using No-ICH.

How do I dose NO-ICH?

Add 2 oz. per 25 gallons (50 ml per 100 liters) of actual water every day until obvious improvement takes place and then add every other day until all fish are normal. When all fish are clean treat 3 more times every other day to ensure no further problems.

Is it okay to dose at a higher level?

In general the dosages noted above should be adhered to but there a few situations that may warrant higher dosage. These would include:

1. Dealing with a very severe or persistent infestation.

2. If you are unable to temporarily turn off your protein skimmer, UV sterilizer, ozonizer or similar filtration equipment.

3. Aquariums with very large biofiltration capacity which may speed up the degradation of the product.

In these cases you would treat on day one with 4 oz. per 25 gallons and then increase the dosage levels by 50% to 3 oz. per 25 gallons every other day until obvious improvement takes place. Once fish are clean treat 3 more times at 3 oz. per 25 gallons every other day to ensure no further problems.

Can No-ICH be used as a prophylactic?

No-ICH (as well as any other treatment) should not be added continually into any aquarium. You can however use No-ICH to help protect against ich outbreaks that commonly occur when new fish are added to an established aquarium. In this case we recommend adding an initial dose when the new fish are added and adding a second dose 2 days later. Observe your tank inhabitants carefully for any signs of outbreak to determine if you need to continue after the second dose.

Can No-ICH be used for treating Freshwater ich?

Yes, No-ICH is also an effective treatment for freshwater ich. It is also the product of choice for safely treating scaleless fish.

In what sizes is No-ICH available?

No-ICH is available in 16 oz. (1/2 liter), 32 oz. (1 liter), 64 oz. (2 liter), and 640 oz. (5 gallon) bottles.

Can I purchase directly from FishVet?

Unfortunately not. Our products are not sold directly to the public. If your local store does not stock these products, ask them to request them from their distributor.
