I used to do water changes every two weeks on my reef. As time went on i tried to reduce it and found it didnt have any effect on the corals growth or the tanks health. If you look back on the thread you will see my tank before i moved it and the sps corals in there are different then the ones i have now. When i moved the tank it crashed and i lost everything except the two lps corals i have and half my zoas. this tank has been set up since august and there hasnt been a water change on it yet. The skimmer and the filter pads in my sump remove the bulk of the excess nutrients which always me to feed the corals a bit more to help with growth. I do add trace elements and lots of iron, iodine, and potassium. Also i have to dose a ton of calcium, alk, and mag to keep up with the corals demands. Dont get me wrong i am not saying i will never do a water change i am just saying i dont see a need yet. Maybe for spring i will do a big 20% change just to be safe and to replenish some of what i cant test for.
