Eheim 4+pro canister running now and will be adding 10g diy sump in a few days. Does anyone have a recommendation on heater/controller that will be short enough to put in 10” wide chamber? Also recommendations on how I should do the refugium. Sand? Rubble? Bio blocks? Mix? Looking to keep some macro in it for nitrates. Some pics of Larry, Susan, snappy the smoocher, and violet.
