On my 180g ive got 1 fx5 and 1 xp3 and 2 huey heung 560l rated sponge filter.
On my 100g ive got 1 fx5 and 1 560l huey heung sponge.
On my 60g ive got one 5piece eheim aquaball and 1 560l huey heung sponge filter
and on my new 350g when i get it ,it will have a 4ftx18x18 sump and whatever else i decide to put in,i think the sponges will go in just as a precaution and dont really want them to dry out .
I use mostly DIY filters in a sump, but I do have three Eheim canisters and an Aqua Clear HOB. For my saltwater tank I use an Emperor Aquatics protein skimmer.
