I'll see if I can dig up the article about using 5g buckets in a sump as a DSB alternative, basic idea was that bucket had x# of inches of sand and sat in the sump, then a maxijet 900 PH pumped water from the sump into the top of the bucket. I can't remember if he drilled holes in the side of the bucket or just let the water spill over the top, either way it's good for aerating the tank and if you have heat issues it could help lower temp, but evaporation is going to be a problem............The guy came up with the idea because his DSB crashed (don't they all at some point?) and this way he could simply yank the bucket out if there was a problem.......I also think he had some macro and livestock that actually stayed inside the bucket with a small 9w light for lighting...Oh yeah, he actually had 2 5g buckets...I'm actually going to install this on my newest 80g frag tank that goes in next week, I'll post pics
