I have a 240 tall with a huge sump, what is better to fill the sump with
Rena Filstars
Ehiem Substrate
bioballs
or can i use all three money is no object.
I am thinking filling it up with 20 gallons of Ehiem Substrate would be cool and amazing filter setup. Same with black rena filstars would that also have way more surface area than bioballs.
Also i have the ehiem sponges they look like scour pads for pots, well i have 20 of them where do these go in my huge ultimate filter
ps it has a skimmer and refuguim but since i am making it an amazon river setup should i just not use these things.
Need tank to house 4 Payaras all 15 to 18 inches!
