I am using 5 Litre Ehiem substrate Pro, 3 Litre Lava rocks, 30 scubbies, and 5 gallons of bio balls in my sump tank.
I am going to take out all the bio balls in my sump tank because I have heard that bio balls are not good to submerse. Replace the new bio media as the chamber is limited space and I want to improve bio filtration.
Which one should I buy? BioMax or Ehiem Substrate Pro? or More scubbles?
Thanks
