Is this also safe for sps.
Question by: Jodine on Dec 6, 2013 6:29:00 AM
Hey Jodine,
The Coral RX dip will work just fine for SPS corals.
Answer by: Bulk Reef Supply on Dec 6, 2013 6:29:00 AM
Will this Coral RX kill aptasia? I have an SPS frag, and there is an aptasia between the base of the coral and the frag puck...
Question by: Paul on Jan 27, 2014 3:45:00 AM
Hey Paul,
In my experience it works best for things like flatworms and red bugs. If you just have an aptasia I would use something like Aptasia X or you could mix some kalk to a bit of a slurry and apply it directly on top of the aptasia. Kalk isn't the greatest route for treating in the tank as it will greatly effect the pH of the tank, but treating a single aptasia external to the aquarium it would be just fine.

The 1oz Coral Rx Pro concentrated is more expensive than the 8oz regular. What are the differences? How much dip water will the concentrate make?
Question by: Phillip on Sep 5, 2013 6:40:00 PM
Hey Phillip,
The Concentrated Coral Rx only uses 30 drops per gallon (roughly 2mL) of water instead of 20mL. This makes it in the ballpark of 10x more concentrated then the standard coral rx. Its generally best for folks making large batches at a time. If your only mixing 1g at a time I usually recommend using the standard coral Rx as its faster to measure out in small quantities.

How to use Coral Rx Hobbyist Blend:

  • Shake bottle of Coral Rx.
  • Add 20 mL or 4 capfuls of Coral Rx to 1 gallon (3.8 liters) of saltwater from aquarium.
  • Mix well.
  • Using a small powerhead, keep the water moving and place coral in the coral dip.
  • If you do not have a powerhead, gently shake coral in the coral dip.
  • Keep coral in the coral dip for 5 – 10 minutes.
  • After 5 – 10 minutes, remove coral and discard the coral dip.
  • Do not reuse the coral dip as parasite may release toxins.
  • Rinse coral with clean saltwater and return to aquarium.
  • Do not add Coral Rx directly into aquarium.

  • Does what it should By Matthew on 8/7/2015

    Its hard to review a product like this if you aren't a chemist or work in a lab, lets be honest. But I can tell you that when you use it the results will be obvious. Any hitchhikers on your corals will go running when you dip. Im probably gunna use it on live rock in my next setup
  • Works beautifully By JEMM55 on 7/14/2015

    One sec in the dip and the redworms came flying out like they were set on fire.
    Nice to know the pests wont get in the tank or screw up my corals
  • great product By Jack on 5/3/2015

    Purchased this as I was getting some frags for the first time and wanted to dip first. All I can say is I am glad I did. I had about 4-5 different hitchhikers that came floating off while dipping. I now dip ever coral I get.
  • Works great By April on 4/13/2015

    Works great. Got some unwanted critters out of my corals before placing them in my tank. I even like the smell of it. :)
  • Great Product By David on 4/11/2015

    Its amazing what gets removed from your new coral after using the material. Doesn't take long for pets to scramble off your coral once submersed in a coral dip solution. I will ALWAYS use this dip.
  • Death to the little ones By MKaplan on 2/5/2015

    This stuff is fantastic. I had a red flatworm infested specimen that I needed to cleanse before I moved it to a different display tank. 7 minutes in this stuff and they all look to be gone. That and a pretty sizable bristle worm I didn't know existed in the piece crawled out and died.
  • Solid Product By Laurie on 2/4/2015

    All new corals get treated with this product before putting in our system and so far no new pests have been introduced! I do have to give one caveat, although I am extremely happy with this product, we have some nasty red planaria that think this stuff is a nice massage.

    Another thumbs up for this product is that it helped bring back a couple corals from the dead. Seriously! The corals were succumbing to slow tissue necrosis and after dipping, they are slowly coming back! That is something that will make any reefer smile...
  • Can't Live Without By CraigD on 1/30/2015

    This stuff is amazing. A total necessity for dipping for protection of pests, however this stuff is amazing to rejuvenate corals. Like a day at the health spa for corals.
  • Awesome By Paul on 12/4/2014

    I was/am new to reefing and using a product I never heard of gave me pause. I was very glad that I did order and use this, I couldn't believe what came off my corals. I won't add another coral to my tank without using this first. Great stuff.
  • excellent stuff By matt on 10/30/2014

    Coral rx is needed if you're running a tank with coral theirs no other way to put it. I used this stuff and you should've seen the stuff falling off my corals!!!! I'll never keep a reef tank without this.
  • Surprised By Alex on 7/19/2014

    Bought this as an afterthought with a bunch of other stuff. I thought, for $3 I might as well give it a try. Tried it on a piece of montipora digitata I got from the LFS with no real expectations. You should have seen the thing that came crawling out of that. Tons of tiny things, copopods, even a bristle worm. Now I dip EVERYTHING.
  • Good product By Sean on 5/26/2014

    I use this EVERYTIME I bring corals home from my local fish store. It's simple to use and important. It takes less than 10 minutes and provides me with confidence that along with new corals, I am not adding unwanted hitchhikers to my tank that will destroy it. It's a bargain!
