Ok so I plan on running a 75gal mixed reef. I have two sumps one is a 20gallon long which will mostly be taken up by the skimmer and return pump the 2nd sump is a little less then a 10gallon tall. I'm open as to what to do with this tank. I was thinking of putting a deep sand bed in it but I know these come with risks. I'm going to run an ATS for sure so is it worth the risk of running a DSB as well or is that over kill? I also have piping set to run two reactors. I'm going to run carbon in one for sure so if an ATS couldn't keep up I could run GFO. Just not sure about the DSB. I keep going back and forth on it.
