Good water flow for goldfish tank

[Agus]

Hi guys, I'm looking for a better way to make my goldfish tank clean from the fish poop. I'm using canister filter for my 45g bare bottom tank and the water flow like this:

Inlet position is 4" from the bottom. The aim is to make a flow that will make all dirt goes to the inlet, but I have to reduce the current that comes out from the spray bar so that the goldfish can swim comfortably. This bring consequences of heavy waste will gather in the red area of the tank and I have to vacuum it twice a day just to please my eyes

Any thought or suggestion on how to make an effective flow?

I keep an HOB at both ends if my tank. My goldies actually play in the flow.

Hi Deanasue, there's no dead spot in your tank? does it suck all the waste effectively?

 

[FishGuest5123]

It does. I also siphon with a python once a week.

Nice, can I see your tank setup?

Sure. Excuse the yellow tint to the water. I just added some Furan-2 for cloudy eye in one of my fish and tints the water. Notice I also have a sponge filter in the center so they have a lot of bubbles to play in.

Thanks for the picture. I've tried using sand, stone and plants as a decor but some foods and waste always getting stuck in there, make it difficult to siphon. And my fish seems don't care to play with bubbles, she just focused on begging for food all the time

Perhaps my gravel is bigger but I never have an issue vacuuming. I get gunk up pretty easily. My goldies hated sand. Stayed away from the bottom until I changed it back.
