Mathdoc’s Reef Sanctuary

About the Owner

I am a pediatrician and a math teacher and have loved and kept both salt and fresh water fish for over 20 years. I have a Koi pond at home and a 180-gallon reef tank in my pediatric office. In general, children are very afraid of doctors and shots. The tank calms them down and helps so much. They also learn about fish and corals so it is an educational experience as well. Before I see patients, they have to sit and look at the tank, and then after they are seen, they spend some more time watching and relaxing.

Additional Notes

  • Problems Overcome With System: I have had many problems including Red Cyaobacteria. I found that when the lights are overdue for a change, the Cyanobacteria starts to grow. I also used Ultralife Red Slime Remover and it works well. I have also had problems with Flatworms. Have not figured that one out yet. Good flow has helped overcome many problems and is an absolute must, in my opinion.
  • Things You Like Best About System: I love the wide spectrum of colors I have and I love having a few soft corals, some LPS and SPS all mixed. It is not easy, but it is well worth the work! Mostly I love that every day 25 or more children can see and enjoy bits of the reef (aquacultured) from all over the world in my office! They learn, enjoy, and appreciate coral reefs more because of this tank.
  • Anything Special Unique About System: Mixed system (LPS/SPS/SOFTIES) and they all get along (well, most of the time, at least).
  • Overall Positives: Great coral growth and I have had many fish over 3-4 years. Amazing colors and textures. The water is always very clear.
  • Overall Negatives: I feed heavily, so I need to skim quite a bit. I also need to use lots of Phosban, carbon and Purigen as well as water changes to keep the SPS happy. The MH lights are very hot and I am thinking about changing to LEDs someday.
