Can Chaetos go without DSB in the sump??
And what's the purpose of the DSB??
Lastly, why coral-chip have to be removed??
Currently, my Sump Tank:
1st compartment - Coral Chip
Center comartment - Chaetos only (No sand and No LR)
Last compartment - FR, Skimmer, Chiller, UV, Return Pump to Main Tank.
Is my SetUp OK??
