k1 & Bioball Sump


New Member
Hey guys, I have been having a headache and a hell of a time deciding on my sump as i wanted to combine the use of both K1 and bioballs. I already have 30gallon of bioballs so i would like to use it. Dimensions for the tank that I will be using for this sump is 72" x 18" x 18". Even though the picture does not show the socks but I will have filter socks in the first chamber with water draining into it from my overflow.
Any feedback would be greatly appreciated.

Pretty nice design but Ull want mechanical first before any bio to keep those compartments clean.


Keep it simple and just run a larger section for the K1.

The trickle tower wont make it any better. It only complicates it.

Sell the bio balls to buy more K1.

I am going to change mine to have filter socks draining into k1. Way easier to deal with than bio balls.
