Gross 17g tank + 12g sump, 58.6GPH return, is it enough?

Hi guys, i have a 17g tank + 12g sump and in order to maintain as quiet as possible my return i will run 58.6GPH return (measured fairly precisely), is it enough?

I have a x-aqua in/out style return (blau aquarist internal overflow) that is basically a durso.

I have put a tiny hose in the little hole of the durso air intake as you see in photo, i do not have gurgling noise it's just the water entering de sump. Water go down pretty straight, no curve, just a straight 20 degree tilt. Return pipe is a 32mm 1-1/4" corrugated pipe entering half a inch in water (i have tried different levels). I have some "splashing" in the sump unless i reduce flow as little as 58GPH.

Is a curve better? or pvc piping?

The short answer is no. You want a turnover of 3-5x your total system volume, or between 100-150Gph.

La réponse longue est .. Oui, vous pouvez le faire avec le débit que vous avez tant que vous avez suffisamment de roche vivante et de mouvement interne (fabricants de vagues). Fondamentalement, vous transformez votre écran en puisard. De plus, les tubes ondulés ne sont pas vos amis. Il réduit le débit et recueille les détritus. La plomberie dure est excellente (PVC), mais les tubes en vinyle renforcé conviennent. <--- I hope google translate did its job...
The above is French/Italian humor...
The long answer is.. Yes you can do it with the flow rate you have as long as you have enough live rock and internal movement (wave makers). Basically you are turning your display into a sump. Also corrugated tubing are not your friend. It reduces flow and collects detritus. Hard plumbed is great (PVC) but reenforced vinyl tubing is fine.

Thanks guys, i've seen that 3-5X is the perfect range but 2.5X is doable. I can go up to 4X without having too much noise during the days and then if someone will have to sleep in the room were the tank is i will dial it down to 2.5X (lowest setting) where pratically you can just hear the AC pump hummm. Seen the price of pvc piping i will try also the hard plumbing, if it's better, why not.

Do you guys advice in doing one 90degree or 2 x 45 degree bend or as straight as possible is better?

2x 45s is the same flow reduction as a single 90, so it's really personal preference, aesthetics and/or whatever you have room for. Silicone tubing is also fine.
