how does the hob fuge work?
Water is brought in by an overflow and flows through a chamber with a sandbed, some LR
and some macro algae, then is pumped back to the tank. This was a HOB
fuge made for me by another member, I do not have any pics of it and it is a pain to try and take any cause of where the tank is situated and then the fuge is behind the tank, sorry. There used to be some pics of it in the DIY
forum, but think the pics have been deleted.
There are a few models available on the market, the most popular being the CPR aquafuge, it works the opposite, water is pumped in and overflows back into the tank, like a powerfilter..
