Red dragon speedy 50 watt as return
Hi Slief ,
Is it possible to have a red dragon speedy 50 watt as a return for a 130 gallon tank with head pressure height at atleast 5 feet ? I cannot have high flow through sump as am restricted by Theiling roller mat as it can accept only 500 gph input to it . Regards, Abhishek |

Forgot to mention that the returns will be divided to feed return loc lines at either end of the tank with 3/4 inch schedule 40 pipes .

f your total head including friction loss is really 5’ then you would be OK assuming 900 gph is enough which in most cases it would be but most don’t take into considering friction loss when determining actual head pressure. You can use the calculator in the link below to get a better ball park of your actual head less. Just select the Royal Exclusiv RD3 50 in the pump selector pull down and fill in the rest of the fields to get an idea of the actual head loss. If it were me, I would likely go with the 100 watt and run it at a lower wattage unless the total headloss is really 5’ or less in large part because I’d rather have more pump than I need and run it at a lower power than one that is right at the edge that needs to be run at full power.

Hi Slief ,
Thanks a lot man for the calculator . With all the vertical and horizontal head losses and taking the 90 degrees and ball valves and unions in view , it's actually exactly 500 gph leaving no room for error . So like you said - might have to look into 100 watt . You might have just saved me a very costly mistake Regards, Abhishek |

Thanks Scott, But I think too late for me to change the pump already bought and I not sure if have time to change or cancel the shipment. Beside I need is a submersible one. The 90elbow should be only 3 but I add one to direct the flow away from direct down inside the tank that blow the sand out. So any alternative? I wonder if I can re do the 0.75 inch pipe to 1.25”. Something I need to ask the tank maker . Look at my overflow box spaces: 564817116.259905.jpg 564817105.566572.jpg Cheers, MD 從我的iPhone使用Tapatalk 發送

That said, this isn’t Royal Exclusiv related let alone RD3 50 related and while I am always there to help you, especially since you’re a RE customer, this topic is much better suited for the Lighting, Flitration and Other Equipment section of this forum. Then you could get other peoples feedback too. http://www.reefcentral.com/forums/fo...play.php?f=212
