More sump discussion, really good stuff in this thread: http://www.barrreport.com/showthread...p-basics/page3
I noticed some higher nitrates lately, and I'm wondering if it is due to me changing the design of the sump. Just recently I removed the drip tray portion as it was badly designed and caused sump malfunctions (floods). This meant that there were no longer any pot scrubbies exposed to drips/air, all submerged. It's entirely possible this reduced my sumps filtration capacity, and coupled with the new batch of fish (dirty platies!), raised nitrates from 10 to 30ish.
Real quick sketch here...water line in the first dump section will be higher...I think.
