Hi Everyone, As my husband posted we just got our new Tideline 62 AIO the other day. We are very disappointed with the stand as on the site it shows it would be made of hardwood and this one is particle board. So we got over that issue and are looking on how to put the filtration piece together..........new to AIO and SUMPS in general so have no clue. No instructions on what goes in each compartment. We figured out that the pumps go on each side for the returns. We are ditching the socks and got some media trays to go where they are. Then the skimmer would go in on of the other open compartments. That will leave another empty compartment. So question is..........do you put anything in the compartment with the skimmer? Do you put anything in the empty compartment or just leave it empty? Or make it into a refugium??
