Sand Wall

Like most people, I chose to make the middle of my sump a refugium. I also wanted to use finer sand as a deep sand bed. So in went the sand, probably equivalent in size to fine sugar and after awhile it looked like this:

The sand kept blowing up as the water came down from the baffles. The issue was that I swapped the location for my baffles with that of the return pump... which was great because it expanded my evaporation space, meaning less frequent top off. However, I didn't foresee the water trickling down the baffles and kicking up the sand. Not a big issue... I just needed to create a "sand barrier".

Once installed, the result is the following:

Now, the sand is no longer where the water comes down.
