    Good to know I am not the only tank “wack” that saves the copepods from the filter sock. Now someone tell my wife I am not nuts-at least not 100% nuts!!

    This sounds good in theory but whenever I’ve tried this all I end up with is a bunch of nasty brown water. Which I’m not all that interested in throwing back into my tank. And I can’t say I’ve ever seen that many pods in the socks. Fortunately I don’t use socks anymore (except for polishing after water change for a day)and I don’t see a difference in my display whether I use a sock or not. Are there really enough pods in the sock to repopulate the system I would think if there were your pod population is doing just fine so why not utilize the free food for the fish. The time I do see a lot of pods during maintenance is when I harvest the cheato. I place that in small bucket with some water and the pods all scatter back to the water. They go right back into the fuge.

    Filter sock? What filter sock? I quit running one about a year ago, have not regretted it. To me They are more trouble than they are worth. I am with Darren on this one.

  • Matt…I tried but she didn’t listen

    I agree, filter socks drive me crazy. I only run them for a day or two after doing some tank maintenance that stirs up the sediment pretty well. Like blowing off all of the rocks. When I clean out the socks I just put the pods into my fuge. Otherwise I go sockless!

    I not only save the pods from the filter sock (I prefer running a filter sock on one of the two overflows), but also spend the time saving as many pods as I can from the macro algae I have to remove from my refugium. I have made this a game with my 10-year-old and her little fingers are perfect for the task.
    Not only does my Mandarin thank me for any extras, I get a chance to “distribute” pods to other locations and tanks.
    It is a little extra effort, but fully worth it in my opinion

    By counting the pods in the filter sock can give you a ideal about the health of your pod population.
