This is my 75 gallon Display Tan. It is a mixed reef predator tank and right up front I want to say I run high nutrients and it seems to be a method that works well for my tank but all of our tanks are different. I only water change monthly if not every other month nd as needed on calcium levels. I try to use my reef octopus skimmer as a dry skimmer and get as close to a chocolate milk skimmate as possible. My skimmer helps me on the water change because its rated up to 201 gal but my entire sstem is only 105 gallon. enough with the chatter though here comes the candy Sorry for the link but I couldn't quite figure out how to do a picture post like I see all the time on here https://www.facebook.com/ricky.cole...1073741826.100000094668731&type=3&uploaded=98 I have lots of sweet stuff rastas, lots of palys and zoas, chalices, montis, euphillia, a gold wall hammer, jellybean chalice, mummy eye 3g, j fox and wwc leptos, blue polyped green monti etc.
