You could use 6mm, you wouldn't see any deflection from that thickness. I've made a few rimless nanos that are 36 long and 8-10" tall with 6mm. Use 3/8" if you want overkill, but I personally...

Currently, gotta be my closed brain, I've had it for over 6 years and grew it from a baby. For an idea on size I would say it's currently pretty close to the size of an actual human brain. And yes my...

Yes very good but that's over 8 feet of head pressure, it's significant but its a pressure rated pump so flow losses are minimal with added pressure. How much power is that using? Around 300W, ouch!...

Yes and no, same flow rate different velocity. The lower velocity and greater spread creates an advantage as simulates natural water movement better.

Tunzes and Vortecs push flow outwards in an expanding direction, this results in a larger area and therefore a lower velocity. Velocity is not that same as flow rate.

Interesting, did you notice that repeatably mentioned the 10x flow is general guideline tank flow but obviously some tanks require more. I just think it's easier to run 10x through the sump and then...

Like I already stated, it takes more experience to run higher flows through overflows properly, it's not for everyone and it's not necessarily better than lower flow. That article is for beginners,...

Mr. Wilson got me curious when he mentioned the temperature his pump ran at so I checked mine tonight.

Would definitely agree, reef tanks are more of an art form than a science. The science is the easy part but making it all come together is what makes or breaks a tank.

And for good reason, quite often skimmer bodies are very thin to cut down on costs and acrylic can become more brittle from extended use.
