should it be alright to put just one header that pumps like 3000l/h behind the btn module with only sphongle media inside? or did i need to put more pumps, should be so nice if i could hide everything so nothing is seen when look into the tank
intake on the bottom of the module and outtake on the top of the module? should i add anything other than sphongle inside the filtration system?
for air i thinking of going with an airpump into airstones.
i found a pump that pumps 5000l/h, i will put blue filters with diffrent size of holes and then bioballs, should the bio balls be last in the filter chain before it goes back to the aquarium?
