    Refugium lighting...

    What light cycles does everyone run o their refugiums in relation to their main tank. Mine is simply on when tank is dark, off when tank is lit up. Opposing cycles. Folks with meters, test-kit madness and keen powers of observation are aware of daily variances in chemical, physical and biological phenomena in their systems. Redox, pH, animal activity are all tied together with time and lighting. Inasmuch as our small seawater volumes fluctuate more than wild reefs, there are definite considerations to off-setting the same with an opposed light regimen on a biological refugium/sump. At itís crudest, all this involves is an alternating set of timers over the main-display and refugium tanks; when oneís off, the otherís on. Voila! No oxygen minima, low calcium, Redox and it helps stabilize the Ph swings at night...

    Just my 2 cents worth and I'm sure it will spark a thread here....hahahaha

    The only thing two reef keepers will agree on, is what the third reef keeper is doing wrong!

    I don't grow macro algae but use mine for culturing amphipods, mysis shrimp, copepods, bristleworms, etc. I don't light it at all but it does get some light from the tank it's next to.
