Honestly, unless you go heavy SPS, you should be fine with constant water changes. I would up that to 10g though because I don't think 6g won't be enough to replenish the trace elements sucked up by our corals.
Yeah I'm going to do 12 gallon water changes, get a riding unit. Also since my waters good and my birdsnest is doing good I got a Montipora cap for forty dollars and its pretty big, a bird of paradise birdsnest for fifty and a Montipora undata for 10 dollars its not huge but for ten a good deal. Pics tommorow.
Ok here is the monti it looks like its white in some areas but its the angle:
Here is one of my montipora undata, anyone know a really good spot to put it? :
Here is my dads birdsnest:
Here is the bird of paradise:
And a picture of all except the monti undata.
