I have a 45 gallon tank, with live sand and close to 45 pounds of live rock. My ph as of today was 8.2, ammonia was 0 ppm, nitrite 0 ppm, nitrate 40. Last week I just started using ro water, I do water changes every other week of 10%. I was using tap water for everything with a water conditioner which now I have stopped. I have a total of 5 small fish (2 clowns, 2 demsels, and a small regal tank), and I can't get my nitrate down the last few weeks, and up until now it was always close to 0. I had a small yellow tang die a few weeks ago and it must have died during the day and by the time I got home the crabs had gotten to it, but everything else is doing fine. And I also had white on my live rock. I also have a protein skimmer and sump. My questions are am I doing enough to get the nitrate level down (I'm guessing I should do more water changes), and what are things needed to be done to keep all the levels where they are suppose to be?
Thanks
Mike
