I have a questions regarding those refugiums with a HOB
What happens when the power goes out? Does your HOB
trickle unit spill water?
Would your refugium start to overflow water too?
Is there a risk of water overflows with these systems?
Can I use a regular tank without those wall dividers as oppossed to the ready to use refugium off the shelf?
What is the common knowledge when it comes to making sure that water doesn't overflow (meaning fill with too much water and spill out of) from the HOB
trickle unit? Or does physics of the setup guarantee that water will not overflow out of your refugium below?
Is a refugium OK to place fish in or would it be too dirty(for a lack of knowledge, sorry for this word) and stuff?
