Im picking up my new 260 gallon tank with corner overflows and cannot afford the $400 for a refugium sump so I would appreciate if anybody can direct me to the right diagrams for a DIY. I really like the Trigger Systems elite model because you can adjust the flow to the refugium section, although I'd rather replace a cloth/sponge every other day instead of filter socks.. I will be using an "in sump skimmer". Thank you.
