About Reef Threads

Reef Threads is a podcast and blog that discusses the most interesting subjects from the various forums, blogs, and magazines supporting the reef hobby. Reef Threads is produced by Gary L. Parr and Christine Williams, two veteran reef hobbyists.

Gary has been keeping aquariums for most of his life, starting with a 1-gal. bowl of guppies. He has kept reef aquariums for the past 15 years. His current tanks are a 65-gal. LPS and leather reef and a 40 breeder that contains azooxanthellate corals. Gary’s other hobby is photography. He specializes in macro photography and currently spends most of his time photographing coral and marine fish. You can see Gary’s work in the Reefs and Animals sections of his website, www.gparr.com. You can contact Gary at [email protected].

Christine Williams started keeping fish while she was still a fetus. While the aqueous environment did lend itself to the hobby, it limited her to freshwater species, and so she decided to be born several weeks early. Through sign language, she demanded that her parents convert her crib into a reef aquarium and thus started her illustrious career in marine ornamentals. After completing her studies in biochemistry and molecular microbiology she went to work at β€œAnimal ER” where unfortunately she was not filmed for the Animal Planet channel (though her feet did make a cameo during a rescue segment). Β She frequently lectures on reef topics including marine animal disease, fish husbandry, human-tank zoonosis, and fish cognition. Contact Christine at [email protected].

    Friends….. I am new to the site. I am the principal of an elementary school in Poland, Ohio. After several years of planning, our school’s library now has a 120 gallon acrylic reef aquarium. It is thriving and completely transformed our school.

    Our school has close to 400 K-2 students who obviously love their aquatic friends. I knew they would, but have been surprised by the amount of support our project has received from the saltwater community.

    Donations have poured in from around the country. The generosity has been absolutely amazing and very humbling.

    Our students help in the care of the tank. An after school program is in the works that will include high school students. Together with our 2nd graders they will work together to research and learn more about the proper care of our fish, corals, and invertebrates.

    The tank has had a huge impact on many of our special education students, too. Seeing their reactions to the tank make every second of time we invest in the tank worth it.

    This project has also increased the amount of fathers interested in volunteering in our school. Their involvement has been amazing.

    Hi there….had posted the following on Manhattan Reefs forum. Very few responses. Had an interest because I travel quite a bit and this fellow GlennF claims other people have started to give this a try with good results. Apparently GlennF has a dosing calculator of sorts that is used monthly…..I think:) Dutch Synthetic Reefing=DSR. This was the post I put in MR:

    Hi there was an article back in Jun 2013 about Glenn F’s 1500 liter reef using his “DSR Method” he is a Dutch reefkeeper.

    So intriguing especially because for me as someone who travels often for long stretches would be great to have limited water changes and adjust with supplementation in place of water changes.

    Does anyone have experience with this method? Seems like very limited info about this method.


    and thanks for listening……love the podcasts as always!

    I wanted to say that you guys are doing an excellent job. I own a LFS /Service Company and from time to time I play your pod casts on my stores speaker system. I have had lots of customers stay in the store alot longer just listening to the pod casts.

  4. Jodi says:

    Would LOVE to share your podcasts, and site with our Ladies only frag swap group! Looking forward to listening and learning!!
    SO glad we found you!

  5. Christopher says:

    Sorry, I forgot the entire point in replying to this thread. I know you guys are busy and have other more important things to do with your lives…But the reason why I enjoy “ReefThreads” and listen is… the information, relative topics, good content and great guest. Plus the two hour commute I endure every day… So if possible, could you guys have at least two more POD cast a week… Thanks again, keep up the good work… we are listening.

    • gparr says:

      Thanks for listening and I’m glad we can chew up 45 min. of that long commute. Chances of us doing two more podcasts a week? Absolutely zero! πŸ˜‰ But we made this week’s podcast an hour and are recording next week’s tonight so we’ll try to add a couple of extra minutes for you.

    Gee, I met Christine for the first time just about three years ago when I started getting involved with the BRS, which must have been pre “ReefThreads”. Had a great time talking in the car to and from the meeting. This past spring we had Christine up to Boston again to speak at another meeting and had the pleasure of being cooped up in the car for another two hours driving back and forth to our clubs meeting. I had a great time just talking with Christine about different topics. I never really knew about reef threads until this last meeting, so I started listening early this past spring. Christine had mentioned coming up to Boston and speaking at our meeting and eating our regionally famous “FISH GOO”… BTW Gary, we have an engraved spoon with your name on it for the meeting we are having in November… Do not let the hobby and the USA down… Anyways, I thought it was funny that some of the following topics on reef threads seem to be related to a good portion of our two hour ride conversation. Aqua culturing/Mariculturing, LED’s, Christines Brother, Christines Father building the cabinet and several other topics as well. Either way, it is good to know that you guys have an idea of what is going on in the hobby. Keep of the good work and I look forward to bending Gary’s ear. I made sure we booked the venue and hotel four hours away from each other… Just kidding Gary. Look forward to seeing you soon and conversing. Jeremy you are always welcome to come up to Boston with Mom for a visit with the Boston Reefers Society… we are all family. Good Luck! Continued Success with reaching 500 POD Cast! Stay well!

    • gparr says:

      Christopher, Thanks for the thoughts. Looking forward to my Boston visit and will do my best to taste the goo. However, I have a very quick gag reflex. πŸ˜‰ See you in November.

    Discovered your podcasts about 2 months ago. I listen to a different podcast everyday as I go for a walk here on Long Island. Just love the podcasts and thanks for doing them!


  8. Brad says:

    Hey guys! I came across this link on the MSN homepage and thought it was interesting. North Americas largest privately owned Reef Tank. Keep up the good work, I love the show.


  9. Macca75 says:

    Hey Guys,

    I’m an aquarist from Down Under in Australia.

    Came across this little series of video clips you might be interested in from a local (well domestic anyway) supplier of fish and inverts. I think Ep 8 sums up exactly what you guys support in sustainable fishing.


    Hope you enjoy.

    • gparr says:

      Thanks for the link. We’ll check it out. Also, thanks for listening. Good to hear from a listener from the other side of the world.

  10. Doug says:

    I had a question……do you have a listing of your podcasts by topic to identify past podcasts of interest?

    Thanks, Doug

    • gparr says:

      Doug, Thanks for listening and subscribing. We don’t have such a list. You should be able to find most by searching for key words. I try to tag each podcast with as many key words as are appropriate. Also note that, due to server space constraints, a good number of the earlier podcasts are no longer available. Some day we’ll have funding that allows us to re-post all of the podcasts.

  11. Manuel Briz says:

    I have found your podcast two months ago and I love it. I have actually listened about fifty of them!!, and because I’m starting on this hobby (I only have a year of experience…) I would like to thank you for your work…
    keep on doing it!!

    greetings from Spain,

  12. Jan says:

    Wow, I just found out about your podcast. I just listened to podcast 101, 102 and 103. I really enjoyed the discussions. I will spread the word. I’m looking forward to the next podcast. I’ve asked that my club consider having Christine give her lecture on “Hazards of a Tank”. Thank you for having these podcasts.

    • gparr says:

      Thanks for listening and we’re glad you enjoyed the podcasts. We appreciate it if you spread the word. I’m sure Christine would be happy to give her talk. It’s a good one. Also consider her new talk on how fish learn. It taught me a lot.

  13. Matt Little says:

    I recently found your podcast and love it. Keep up the good work!

  14. terry siegel says:

    Craig Bingman just told me about this — very interesting indeed!

  15. Randy elmore says:

    How would I contact you regarding having you speak in the future at our clubs meeting?


  16. Helpy says:

    Hi Gary, how is Sara doing?? is she already out of bed?? it will be nice to hear her even when she is out of the hobby.

  17. Gary Parr says:

    Thanks to all who have asked about Sara. She has recovered and is fine, but has left the hobby. It’s unlikely she’ll be returning to Reef Threads.

    • Alex says:

      Sorry to hear about Sara leaving the hobby. I’m sure she has her reasons and I wish her the best. I just started getting into the hobby and I’m going through all the podcasts as I find them invaluable. Christine is doing a great job as a host and I enjoy her viewpoint as a scientist. Thanks for keeping her around.

  18. Jake says:

    Christine is doing a great job but I’m concerned/worried that we haven’t heard anything about Sara. Is she okay? Is she still part of the show? Will she come back?

    Thanks for all you guys do!

  19. Patrick Eddy says:

    i was playing the podcast at work today and got to thinking, there is no talk of sara any more. how is she doing?? updates please.

    thanks Patrick

  20. Jake says:

    How is Sara? Get well soon!

  21. Mike says:

    Sara get well we miss you!

  22. Marius says:

    Gary and Sara,

    Thank you so much for your awesome podcast. I listen weekly while changing the water on my 90 gallon reef tank. I’ve learned great reef and photo tips from you two!

  23. Alexandre George says:

    Hi Gary and Sara,

    Thank you for placing my Reef in this great site!
    In this site great reports exist and certainly I’ll be an assiduous visitor.
    Best Regards
    Alexandre George.

  24. quickfinger says:

    Just wanted to let you guys know I am a big fan of the show. It’s the best reefing podcast out there by a long shot. Keep it up and thanks….

  25. Tim says:

    Just wanted to let you know that I really enjoy your podcast and I’m not even a reefer (and don’t plan to be!). I keep a freshwater planted tank but find your topics and delivery interesting nonetheless.

  26. Tal Sweet says:

    Just found you guys. Guess I have some catching up to do. πŸ˜‰

  27. Just discovered your site…a pleasure. And generated by two wonderful people. Wishing y’all the very best of luck and life. Kindly, Anth-

  28. Dr Lopez says:

    I love the podcast. Look forward to downloading then every week. I listen to the casts in my car driving to the hospital or whenever i’m alone.

    Thank you

  29. Mike Weston says:
