Master Reefer

Master Reefer (8/13)

  1. Hello, everyone, I'm moving soon and I'm going to use this as a chance to take a temporary break from the hobby. I have a complete 28 gallon set-up with livestock and a ton of supplies that is free to a school, or the like, to be used for educational purposes. WAMAS has helped me a lot over years with this tank so I'd like to give back. Is there any interest? If so I will post more details. Thanks! Jeff
  2. There is nothing wrong with your thought process. Two points: 1) there are tons of cruise controlled awesome reefs whose reefers don't worry about this, and 2) use data that you collect and not what a company tells you. At the the end of the day -- its all marketing. When you make up fresh saltwater with RC and test it -- do you get the same values that's on the package/table? If not, why trust the table? Tom's last post is spot on -- as usual! Jeff
  3. Thanks! Yeah -- I haven't posted in while!!
  4. I don't think the actual brand of salt really matters. Instant ocean has been around forever without changing its recipe (despite the knowledge boom over the last 10 years) and people swear by it. They key is to just be consistent. Like most reefers (like Spidey) I pick my mix based on how well it dissolves in the water. For me, Instant Ocean left a lot of residue which doesn't hurt anything but isn't as clean as I like it. I use Red Sea Coral Pro. Are you worried that a WC is causing your params to jump around? You can test that by: 1) testing the tank water before the WC, 2) testing the tank water after the WC, 3) test your freshly mixed water, and 4) testing your new saltwater just before you do a WC. I used to test my new mixed water params on occasion, and when I open a new bucket, but all I learned is that it really doesn't matter. There is no reason to think the values you pasted above are true or will be the same when you mix it up.
  5. That was most likely the culprit to the short life span.
  6. I agree with all above. pH probes have a limited lifespan and proper care can extend it. Tons of info on the interwebs on proper ph probe care. The pH probe is an electrical device. When the pH probe reaches its end of life, the compensation voltage offsets exceed the operating range and so the probe can no longer be calibrated. If you are really keen on observing pH, then I recommend having at least 2 (one on apex and one stand-alone) to maintain your confidence.
  7. Great project -- I can offer this link for one perspective:
  8. Reefdvms on YouTube just posted an awesome vid on this topic.
  9. We should definitely have these for MACNA
  10. I think she meant that they don't have a respiratory system. Jelly fish are cnidarians the same biological family as coral so they get their oxygen by diffusion through their tissues. I don't think they need much oxygen, but they need it. But anyways -- I want that tube.
  11. I use this one. http://www.plastic-mart.com/product/2460/20-gallon-upright-rectangle-flat-bottom-tank-sp0020-om They have different sizes: http://www.plastic-mart.com/category/28/flat-bottom-portable-water-tanks
  12. Nice Rob. Has anyone tried to pre-coat a frag plug with coralline algae before attaching an SPS frag? I wonder if it would speed growth and healing of the fresh cut frag.
  13. Yeah - I don't disagree with that. I think that out of all my tank worries hydrogen sulfide would rank pretty low. And if you have pods that like stinky black crud, then you should be good to go.
  14. It's probably an low oxygen area that was colonized by sulfate-reducing bacteria. http://reefkeeping.com/issues/2005-12/rhf/
  15. I'll add one other variable to the mix. Slow tissue necrosis can be caused by bacteria (possibly vibrio). If it is bacterial, then you can either frag the coral about a half inch above the necrosis line (to make sure you are fragging healthy tissue) or reduce the amount of light on the frag until heals. By heal I mean stop dying. Low nutrients plus high light PAR stresses the coral (so much light -- so little food!) and that may inhibit its immune system to defend against bacteria.
