And very importantly it increases biological filtration as well..![]()
With a sump you have alot of space for filter media. You can design a plennum in your sump for use of a DSB, you can also use the plennum compartment as a de-nitrafyer (remove nitrates even more by adding various macro algae) Basiclly a sump is like a small filter factory with so much flexibility and diversity, much better than any canister. Any way that is myy opinion.![]()
