What Is In API’s Super Ick Cure?

API is a little bit vague about their API Super Ick Cure product, and rightfully so.

The FDA is very concerned about copper-containing Malachite Green ending up in the tissues of food fish. And they’ve set about stamping out Malachite Green in as many products as they can.

super ick cure
Super Ick Cure is a malachite green stain that effectively taints the epidermis to kill swarmers as they re-enter.

API labels their Super Ick Cure product as “benzaldehyde green” which puts its “Malachite green” identity under the radar, at least for now.

Here are the different “aliases” for Malachite Green: “Aniline Green; Benzal Green; Benzaldehyde Green; China Green; C.I. Basic Green 4; C.I. 42000; Diamond Green B; Diamond Green Bx; Diamond Green P Extra; Fast Green; Light Green N; New Victoria Green Extra I; New Victoria Green Extra II; New Victoria Green Extra O; Solid Green O; Victoria Green B; Victoria Green WB ”

So when you see any of the above, you’re looking at Malachite Green. And that’s FINE. (Reference)

What else is in Super Ick Cure?

Well there’s PVP – which is the active ingredient in Stress Coat, it’s a biofilm that protects and coats the epidermis. I am sure they’ve doped it out to allow the Malachite Green to stain the epidermis chemically and make it toxic to the Ich Swarmers, but ALSO perhaps to coat the skin physically and make it harder for the swarmers to re-encyst en masse. Don’t know. Don’t care. It works.

There are many other references to the presence of Methylene Blue and a Furan antibiotic in the medicine. They’re NOT on the label. I doubt that these compounds are in the Super Ick Cure, and if they are, API is commiting a crime putting those things in the bottle but NOT on the label. And I SERIOUSLY doubt API would stoop to that.

Nope.

“Benzaldehyde Green” is the reduction of Malachite Green in the presence of an aldehyde to Malachite Green Chloride. (Reference)

So, essentially, Super Ick Cure’s just Malachite Green without saying so but there’s a clever twist in play.

When the Malachite Green Chloride goes into the fish, it’s complexed in the tissues and STAYS there (for a while). It’s “leucomalachite green” in the tissues and remains toxic to the Ich organisms when they re-enter the tissues to ‘encyst’.

So while the malachite green is killing the swarmers in the water, it’s also staining the fish, residing in the epidermis, and killing the swarmers as they encyst in the tissues. Super Ick Cure’s essentially breaking the life cycle, HARD, in midstroke.

The thing is, you have to get a high enough amount of Super Ick Cure into the water to STAIN the fishes’ epidermal cell layer WITHOUT killing everything.

And when I say ‘killing everything’ I mean snails and shrimp. I’ve seen vendors saying that Super Ick Cure won’t kill shrimp and harms snails.

If done right, it SHOULD kill snails. and if it doesn’t then HOPEFULLY you’ve done enough to kill Ich without somehow killing off your Trapdoors. Formalin Malachite Green will kill almost all your snails. Not all of them.

I HONESTLY would NOT believe ANY vendor who swore it wouldn’t kill shrimp until you (or someone you trust) has tested it on shrimp. And I haven’t.

Why does the Super Ick Cure manufacturer make such a big deal about the temperature?

Ich moves through its lifecycle MUCH faster when living in warm water. When the organisms are encysted in the skin and in the packet on the bottom of the tank, it’s VERY hard for anything to kill them. Malachite Green has its best chance of killing the Ich when it:

  1. Is vulnerable coming UP from the packets on the bottom as swarmers
  2. Is vulnerable as it re-enters the fish once the fish is stained with leucomalachite green.

At higher temperatures, the Ich will pop off the fish and drop to the bottom, multiply and swarm FASTER and therefore CLEAR FASTER. And since the Malachite Green is in the tissues for a limited time, manufacturers and researchers had to synchronize the life cycle to the amount of time they could keep the fish stained.

When you buy Super Ick Cure with this link, I get 0.02 cents towards my retirement fund. LOL

What’s in Ick Guard by Tetra?

Well that’s Malachite Green (Victoria Green) and Acriflavine. Benzaldehyde Green And PvpBenzaldehyde Green ChemistryBenzaldehyde Green And PvpSo it’s got a little more power against a wider range of ciliates. Tetra’s Ick Guard (Buy) should have some impact on Lymphocystis virus megalocytes as well.

This is The LCD Screen Scope
We Did The Tutorial With. I did a twenty page tutorial (Here's the tutorial) with video, audio, images and even little parasite movies to show you how to use a microscope. 

This Filter is Good For BIG Dirty Tanks
I've been wrestling with water quality with the turtles. The sponges work GREAT, but in THOSE turtle systems where they eat MICE the poops are bulky. This filter can handle it. In "Tortu's" tank, it's got an 800 gph pump and it rocks. 

PraziPro for Flukes
They nailed it. Figured out the solubility and worked out the dosing. It works. 

Buy Some Good Koi?
No, this isn't really for the 'high end' collector y'all. But for someone who isn't near a decent garden center, here are "good-to-quite-good" Koi you will like at a very good price. I know these guys personally.

Best Food, Ever
It's made for (and I discovered it for) my Blood Parrots but the small size, intense color enhancers and excellent formulation make it superb young-Koi food. Oh, and it's AMAZING on color-cichlids like Flowerhorn and Blood Parrots. 

Pro Air 60 Aerator is a VERY high output air pump pushing my whole fish room (17+ drops), and I have one at home driving everything there, and I have one as a back up. 

Formalin Malachite (Not dilute)
There are formalin malachite preparations at 10%, 22% and 37%. There's economy in the concentrates. Hard to get Prime shipping because air transport is curtailed. This is a good value on 32 ounces. 

Topical For Koi and Pond Fish Ulcers
I like 7% tincture of iodine because it stains but it's hard to hurt anything with it. Used with a WOVEN gauze, this works well to clean and disinfect a wound. Only use ONCE. Do not 'repeatedly' scrub wounds. 

Confectioner's Glaze 
Is the way to bind a medication to fish food. Gone are the days of paste food and oil. The write up is done, it's RIGHT HERE.

Koi Health & Disease
Hopefully this link takes you to the newest edition by PRIME to get it to your house the fastest. 

I have over ten of these Titanium Heaters in my fish room and at home. They're a paradigm shift in aquarium heating. They're titanium and 400W for under $30! Whaaaaaaaaat?

CyroPro by Hikari is safe and easy for Anchor Worms and Fish Lice.

Whatever heaters you use, back yourself up with a temperature controller, it'll turn on, and off your heaters. If your heater seizes "on" at least the thermostat will stop a tragedy. 

LifeGuard by Tetra is a tablet version of a tame 'chloramine-t' or 'halamid' compound that's easy to get and good on bacterial infections, in baths. 

Antimicrobial
If you're making medicated feed for a larger group of fish, this will come in handy. Dosing is available in the site. 

For me, filtration-of-choice
For aquariums, even small Koi holding facilities or small ponds. These sponge filters are cheap, easy to clean, and they clear hazes very well when used with some Accuclear or similar.

Rubber sided, round, nettable tanks
Make great hospital or quarantine facilities. They SHOULD cost about $200-300 depending on size, but this, lower quality unit (while panned in some reviews) may be good. Don't overfill and make sure it's propped up.

1200 Watt heater, on a thermostat held securely above the waterline, works GREAT as a large tank heater. That's all I'll say because there's risk of electrocution and all that. But then, even in a bucket you could get killed. Sound like fun?
I have several of these ALLIED PRECISION stainless ones that are a couple years old. Working still. 

Potassium Permanganate 
500 grams could be a lifetime supply but it's 50% more than the 100g cost wise, for 500% more amount. Dosing is in the site and the book.

What Does Ajax Eat?
I looked for something well formulated, with meat as the first ingredient. Something UNDER $2/lb and something they could deliver for free. And this was it. He looks and feels great on it.
