Hello, after doing a bit of research on refugiums and discovering how benaficial one may be for my aquarium I've decided to make one.
I found a few links of people modifying aquaclear filters into them so im going to be taking that road and even managed to pick up a aquaclear 150. Now this is where my questions arise as to what exactly do I put into the refugium, Ive heard cheato? but what exactly is this and how is it benaficial? would the refugium need a sandbed? and how deep? is deeper better? or should it be shallow?
should the subtrate be fine or course?
Im sorry for all the questions , but this should serfice for now
and for your time...
