Fish Folk Posted January 11, 2021 Share Posted January 11, 2021 (edited) Over the past year, we've really enjoyed watching some good videos on building and using Freshwater Sumps with larger aquariums. Corvus Oscen (aka Joel) has some excellent videos he put out a while ago. At our LFS, the 125 gal tank they sell plants out of has a freshwater sump. We've never used one before. Most of our tanks are small, and we haven't really been motivated to try drilling tanks, etc. But it struck me that perhaps there are some advantages I've just not been aware of. For example, can a sump be set up to crunch nitrates so well that water changes can slow down significantly? So . . . for those who've tried them, are they worth it? And what have you found to be the best part? Edited January 11, 2021 by Fish Folk Link to comment Share on other sites More sharing options...
