so basically....to start my reef i jes need to get rid of the bio balls and get a better skimmer??
how should i place the lr
rubble though? should i place it directly in the sump orr should i still put it on top of the grid (plexi wit lots of holes on it) so that the water still drips down to the sump? another thing...would it jes be much better if i make a refugium instead of using this wetdry with lr
? can anyone give me plans for a DIY refugium using a 20g tank?
