i dont really maintence it well. just claen out the protien skimmer and add water. i have a few different corals going strong. to my surprise the other day im looking in my tank and see little arms sticking out of the gravel. my anemenie had babies. i got 3 little guys and they eat cut shrimp like champs. just excited because in all my years of fish keeping (even guppies) nothing ever breeds.
