I have read the sticky about the basic equipment and dont see sump/refugium under "basic equipment" on the link Stock list and tips for maintaining your SW tank.
I am researching a lot of aspects of the hobby and am curious what the benifts of such a setup is? It isn't mandatory, correct?
My understanding is that the filtration should be enough from the skimmer and LR
, so what does this sump system do?
I just purchased a 56gallon cube tank with stand and am researching online and buying books about reef tanks and this seems to be a great source of knowledge to help me better understand the hobby.
Thank you for your help,
