Filter for 5' x 3' tank

[Tig Phish]

So acrylic 5' x 3' x 2' acrylic tank. Stock is 2x BD rays, 3x datnoids, 1x VATF, 1x kelberi pbass, 1x arowana. I'm using a 75 gallon sump. K1 or wet/dry with pot scrubbies sump? Also where should the intake and outtake holes be? I'm thinking on using this pump:

Stand will probably be 3' tall.

Okay what if I took a 5 gallon buck. Drill holes in the sides. Put bucket in the 75 gallon tank. Fill the tank up to the 4 gallon mark. Fill the bucket with 2 gallons of K1. Airline inside the bucket. Thoughts? Would I still need baffles? Im thinking about adding bio rings on the outside of the bucket

I would build a full k1 moving bed.make one baffle beside your pump and your done.
What I have done as you can see in the picture, one piece of acrylic with about 600 holes that are smaller the the k1 5/16 (.3125) so the k1 can't get into the next chamber and behind that is a piece of glass to designate the water hight before my drip tray. It works great

I've heard that K1 is best in a cylinder container though

Not true you can make it work you have to keep the air flow directed so the k1 will not get stuck in the corners. I have no issue with k1 getting stuck in the corners in my filter it took a while and a few different air stones to get it right.

My chamber is 24x22

K1 is loud. I have bio balls. I'm old school didn't even know what k1 was until I joined here.

 

[millerkid519]

K1 is noisey but if you cover it properly it is not noisey at all my pump make more noise then my k1. I don't know why lifegard aquatics called there pumps quiet ones lmao

I have a 65lpm pump on my chamber

Yeah I guess just depends on the setup my tank is dead quiet can't hear anything. My 10 gallon is louder because of sponge filters. I have filter floss with custom tray to take out and bio balls and plants and fry in my sump
