Freshwater Dip

What It Treats
Provides temporary relief for a wide range of diseases:

1) Marine Velvet Disease (Amyloodinium ocellatum)
2) Brooklynella hostilis
3) Uronema marinum
4) Flukes (Monogeneans)
5) Black Ich (Turbellarians)

Can be used to confirm the presence of Flukes (see video below).

How To Treat
Fill a bucket with RODI water, and use a heater to match the temperature to the water the fish is coming from. Aerate the water heavily for at least 30 minutes prior to doing the dip, then discontinue aeration while performing the dip. Fish aren’t overly pH sensitive for short durations like this, but you can squirt a little saltwater into the dip just before the fish goes in to help bring it up.

Place the fish in the freshwater (FW) dip and observe closely. It is not unusual for them to freak out a little at first. Also, tangs are notorious for “playing dead” during a FW dip. The important thing is to watch their gills; they should be breathing heavily at all times. If breathing slows, it’s time to exit the dip! (It's also important that the fish remains upright & swimming at all times, so chase him a little with your finger if he lays on the bottom.) Dip the fish for no longer than 5 minutes. Multiple dips may be done, but it’s important to give your fish 24-48 hours to recuperate in-between dips.

For flukes, use a dark (preferably black) bucket so you can see if tiny white sesame seed looking things fall off the fish (especially out of the gills) at around the 3-4 minute mark. The worms will settle to the bottom, so you can use a flashlight to look for them there as well.

ProsProvides temporary relief for a wide range of diseases in a chemical free environment. Can “buy you more time” until a proper treatment can be done.

Cons/Side EffectsNot a permanent “fix” for any disease, as FW dips are not usually effective enough to eradicate all of the parasites/worms afflicting the fish. (So, followup treatment in a quarantine tank is a wise course of action.) Some fish can have an adverse reaction to a FW dip by appearing unable to maintain their equilibrium once returned to the aquarium. If this happens, hold the fish upright (using latex, nitrile or rubber gloves), and gently glide him through the water (to get saltwater flowing through the gills again). It is also a good idea to place the fish in an acclimation box until he appears “normal”.

I have a ? I had two clownfish a wyoming white and a davanci in my new tank I was using them to help cycle my tank. both fish are now dead .my tank is empty other than livesand and some rocks which are not live. I was originally told they died from gillsfllukes now one of the local fish stores is saying more than likely it was Brooks . my ? is what do I do with my water now ? and how long does it take to kill either one of those diseases ?
thanks in advance Denise

You will need to go fallow (fishless) for 6 weeks to starve brook out of your DT.

@Humblefish I have a question as a new reefer, obviously there’s a difference between best practice and what is accessible. I was wondering the effectiveness of using freshwater dips to treat fish with marine ich or other diseases.
As a new reefer cycling and water parameters were an issue, so proper quarantine of anything wet was more problematic than practical.
I’ve employed ich management with a UV and tank husbandry. But I was wondering when I see signs or to remove flukes etc. would freshwater dip without QT and treatment promote positive effects or excess stress? (use of fuge as acclimation after, until equilibrium is right)?

Check out peroxide dosing. That would fit your management much easier, and likely more effective. Use the search box in upper right. You won't have to attempt catching all of the fish that way. Peroxide is essentially an aqueous oxidizer like uv and ozone. But, instead of being limited to just the small reaction chamber, it can reach most all of the wet surfaces. I've used it myself for alage, and also to buy a few days time to set up a QT, but never as a full management protocol. Others have shared thier experiences under the Peroxide dosing thread.

I'll post a few links below for you to read:
