Sump Refugium for Water Changes
Sump Refugium for Water Changes
I use my sump refugium for water changes. I have a 100-gallon system. For a 20% water change, I use the 20-gallon return compartment. The return pump is stopped, the compartment siphoned, new water and salt is mixed in the compartment, heated, and the return pump restarted.
For a 33% water change, I remove the chaetomorpha and use the entire sump refugium. As I am siphoning the water away, I will remove the standpipe to drain the overflow as well.
