Simulated Fish Posted December 6, 2015 Share Posted December 6, 2015 Hey guys I am going to start prepping for a larger tank that I will be setting up over the next few months. I want to get a 75 to 120 gallon tank and I know I want to do a sump. As much as I LOVE my AIO tank I can't justify dropping 2, 3, 4 grand on a larger AIO tank. Plus why miss out on all the DYI fun! SO I know I want to run a sump but in all my googling glory there is a big question I can't find an answer to - how big do I need the return turnover to be & how much water is the siphon going to pull? So if the siphon is only pulling 150gph can I use a pump rated at 150gph or can I go bigger? Please excuse my ignorance but this an area of reefing I know little to nothing about! Thanks in advance!

Mojado Posted December 6, 2015 Share Posted December 6, 2015 Just make sure your pump doesn't push more than what your siphon can pull. I'm sure you've accounted for headloss too. You can always add a valve at the pump output to reduce its output. Folks incorrectly think doing that is bad for the pump, but it's not. . .actually it reduces the work the pump has to do. 150 gph seems to be on the low side for a tank that big, tho. Is your siphon rated for a tank that big? Also, you if you're planning the tank out now, i'd go with a drilled tank and overflow vs siphon method. Link to comment
nismo_sky32 Posted December 6, 2015 Share Posted December 6, 2015 http://glass-holes.com/1500-In-aNd-Out-Complete-System-1500inandout.htm I would look at the overflow kit. I have the nano and love it. http://synergyreef.com/product/16-synergy-reef-overflow/ Here's another a lot of people like http://reefsavvy.com/the-reef-savvy-difference/ And probably the best of the best Link to comment
righttirefire Posted December 6, 2015 Share Posted December 6, 2015 So in my research you want a sump to turn 7-10 times volume, I assume display, for filtration. A pump will "lose" flow to head height and fittings restrictions. So I say research! Link to comment

I was just throw in a number out there, I do plan on drilling, is a over flow not the same as a siphone :s Link to comment

Mojado Posted December 7, 2015 Share Posted December 7, 2015 I was just throw in a number out there, I do plan on drilling, is a over flow not the same as a siphone :s Well, some overflows use a full siphon, but when I hear siphon, my first thought is a hang on back with a syphon that goes over the top of the aquarium top. The glass-holes box you linked, for example, can suck upto 1500 gph. As long as you pick a pump that is less than that, you'll be OK. The more gph the pump pushes, the higher up the grates the water level will be. That is how the overflow box will self-regulate the drain gph to match that of the pump automatically. For example, if your pump pushes (including head loss) 500 gph, then the display tank water level will rise up appx 1/3 the height of the overflow box grates. A pump that pushes 750 gph will result in the water level being appx 1/2 way up the water grates, etc. 1200 gph, the water will rise appx 4/5 up the grates. Link to comment

Thank you, I now under stand flow vs return rate! Link to comment
