Freshwater Dips in Marine Fish Disease Cases

This pertains to SALT WATER fish.

Freshwater dips. I want you to be cognizant of the following about that procedure.

* 1) Fish vary in the amount of time it takes for them to become stressed by the freshwater dip. Some marine fish seem to actually like dipping. Others become weak and near death in as few as 1-2 minutes, so alertness is the keyword.

A minimum dip, if the fish seems to be doing fine and you are bored waiting, is 7-8 minutes. It has been shown that 7-8 minutes is enough time to clear the fishes’ surface of parasites. But you have no choice if the fish appears stressed before that time: Remove him.
* 2) Use water that is dechlorinated by time, or by chemical dechlorination.
* 3) Use water that is the same temperature as the system, or mother tank.
* 4) Use water that has the same pH as the mother system, eg about 8.3-8.5
I routinely keep a Marine Buffer or African Cichlid buffer on hand for buffering the pH of freshwater dips on my marine specimens.

* 5) After the dip, do not dump the dip water back into the tank. It is said that loosened parasites can be revived upon return to the marine environment, and in the case of Trematodes, (Black Ich) I could see this happening. Trematodes may be better handled with PraziPro.
* 6) Dips should be done daily or every other day depending upon the fishes’ response to it. If the fish is very weak, every other day may be all it can stand, but if still strong, daily affords more complete parasite eradication.
You will be dipping for a 14 day period, so get out your galoshes.
If you treat with copper, and can confirm that you have maintained the copper level at 0.2 ppm, and the fish is still not well, then stray voltage may be playing in the case.

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.

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.
