I don't dip new fish I am already going to QT which is every new fish for me since everything goes in QT for at least 5-6 weeks. I also don't acclimate fish other than temp acclimate, instead I match the sg in my QT to the water the fish came in. I ask the vendor what they keep the sg in their systems at before I get the fish to have it matched ahead of time. I then allow the fish to adjust and become comfortable and eating well before I treat/dip anything for a couple of days. Since freshwater dips do not get rid of all suspected parasites I treat them with prazi. My new plan is to also start doing TTM on all new fish thanks to @Humblefish for all the very informative information he posts.
So long as the SG matches in your QT and the "bag water"... AND temp matches in all three, you can perform a 5 minute FW dip prior to placing your fish in QT. A FW dip accomplishes two things:
Freshwater Dip: Provides temporary relief for Brooklynella, Flukes, Marine Velvet disease (Amyloodinium); possibly even Ich & Uronema marinum (both unproven). Can be used to confirm the presence of Flukes.
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 tank water 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 during the dip. If breathing slows, it’s time to exit the dip. Dip the fish for no longer than 5 minutes. Multiple dips may be done, but it’s important to give your fish a day to recuperate in-between dips.
For flukes, use a dark (preferably black) bucket so you can see if tiny white worms fall out of 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.
Pros - Provides 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 Effects - Not a permanent “fix” for any disease, as FW dips are not potent enough to eradicate all of the parasites/worms afflicting the fish. 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”.
- Provides temporary relief for Brooklynella, Flukes, Marine Velvet disease. There is some evidence it does the same for ich & uronema, but both are unproven. However, a FW dip is incapable of dislodging ALL the parasites. I've experimented with this many times, and at least some of the parasites come back even after performing a FW dip.
