JBJ 28 External Refugium/Sump Question

[chadgarner]

I am planning on adding a external sump/refugium to my established JBJ 28 gallon. Since it is full of livestock i don't want to drill the tank.

 

Any body have experience with attaching an HOB overflow to the JBJ?

 

Or experiences with external sump on a JBJ?

 

 

I am thinking of a small 5.5 gallon sump/refugium with some baffles to compartmentalize it. Like anyone else I am just worried about the varied flooding situations that can occur. If possible i would like to make a flood proof system.

 

Any help or suggestions would be great.

 

Thanks in advance.

No experience with the JBJ. But it should be possible depending on how far you want to go to add a HOB overflow. A drilled type overflow will generally be safer from flooding than a HOB type.

 

To make any real difference you should try to increase the fuge size to around 20% of total tank volume. So a 10g would be better than a 5g.

 

I just drilled my BC29 and added a 15g sump with half as a fuge. It is a pain I know. But more piece of mind for me that the HOB doesnt air-lock and cause a flood.
