This has nothing to do with this thread BUT
I just came across this thread, Have any of you ever tried the sugar/vodka method. The way this works is almost like the DSB bucket but a lot easier. When you add sugar or vodka ( They both do the same thing) to your tank it feeds anerobic bacteria. They eat the sugar , then the sugar is gone, so now theres a million bacteria in the tank with nothing to eat. So they eat your nitrates, at the same time your skimmer skims out these bacteria that have nitrates. Therefor lowering your nitrates
I have a red sea test kit and my nitrates were off the chart. I'm guessing at least 60-80ppm, the test kit didn't go up that high. So I decided to add a little sugar since water changes were useless. In 2 weeks my nitrates were down to 0 ppm and have stayed there ever since. I did not do a water change in the sugar period and haven't done one in a loooong time. Now in my 92G tank I have a few damsels, 2 clowns, pajama cardinal, and two medium size tangs, I have never had a nitrate problem since. I have started manyt threads on this and steered many people in the right direction. Also I do not know one person that has lost any livestock including corals doing this. If any people are interested let me know, I'm here to help
