Water quality

I am just looking for some feedback on the water side of my enclosure ( I can also increase the percentage of water to land if this is suggested). I do use a whisper filter but I am noticing a tainted color to the water which is from the eco earth substrate run off. I do have a build up of rocks underneath the land portion to keep the substrate from being in contact with the water but it still does not prevent the water from looking tainted. I included a link to a picture of my enclosure. Is this an issue to be concerned about or is this fine as long as I keep up with water changes? Any help with this issue would be much appreciated.

Its ok if it does that, but do a 50 percent water change every week
