Tccompwiz Posted January 19, 2014 Share Posted January 19, 2014 I am helping a couple who moved into a house that has a built in aquarium. It has 2 2" pipes in overflow and 2 output of I think 1.5". I don't know what size pumps to get. How much water should we move in an hour. It's set up for two pumps. Tank is 58"-31"-31" sump is about 40-50 gallon where water lvl stays.

victoly Posted January 19, 2014 Share Posted January 19, 2014 What are they wanting to keep in the tank ? Quote Link to comment Share on other sites More sharing options...

Tccompwiz Posted January 19, 2014 Author Share Posted January 19, 2014 Reef. Mostly Sps annenomies and fish. From what I've read I'm seeing 750-1250gph. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
nvrEnuf Posted January 19, 2014 Share Posted January 19, 2014 http://www.hamzasreef.com/Contents/Calculators/PumpTurnover.php Generally accepted flow rate of at least 10 X /hr gets her done as proven by Redsea max, biocube, etc. However, I think if I had two pumps to work with I'd go with 20X/hr times 2 pumps. Then add in some sort of flow control. Either at the pump or in line. Why not have the redundency? Sounds like the tank was set-up for it in the first place. This will also give you plenty of power for anything you want in the future provided you add in a union or two to provide easy acsess at a later time. You'll find all the calulators you need on that site BTW. Quote Link to comment Share on other sites More sharing options...
+Grog Posted January 19, 2014 Share Posted January 19, 2014 If that is the flow you want and have dual overflow lines, I'd say put in two Eheim 1262. That is what I'm running and they are quiet and reliable. They are rated over 600 gph with 4' of rise. If you want a little more flow (and a more heat and noise), or save some $, add a Mag 9.5 or 12 in place of one of the Eheim pumps. Plumb them with unions so you can remove easily for cleaning. I'd go Eheim though. This is just an off-the-cuff general suggestion. The space available in the sump/return area may dictate you get one pump over another. Measure first and make sure things fit.

Tccompwiz Posted January 19, 2014 Author Share Posted January 19, 2014 I was thinking 2 of these http://www.marinedepot.com/Iwaki_WMD20RLXT_Water_Pump_(American_Motor)_Up_to_1000_Gallons_Per_Hour_External_Aquarium_Pumps-Iwaki-IK1223-FIWPEPZT-IK1225-vi.html also they have a chiller but being as it was left in house I don't think it works. I assume they had a in sump pump for the chiller returning to sump. The lift on the aquarium would be about 6 -7 ft. I thought about running chiller through a main pump but I worried about loosing to much flow for the aquarium height.

Timfish Posted January 20, 2014 Share Posted January 20, 2014 Depending on the corals you keep you may want pretty high flow rates in the tank but through the sump just a few turnover per hour are acceptable. Personally I would go with two pumps, redundancy I would consider more important than having a high flow rate through the sump. This system had at various times 20X to 30X turnover in tank but only had 5X going through refugiums and 10 X through a final sump: I would encourage your friend to get a copy of Delbeek and Sprungs "The Reef Aquarium" Vol III (it's available on ibooks) it does a excellent job of covering water chemistry and the various filtering methodologies used (from the sumpless, pumpless, skimmerless systems by Lee Chin Eng and Dr. Jaubert to the complex mesocosm by Dr. Adey). I would also encourage them to get a copy of J. E. N. Verons "Corals of Australia and the Indo-Pacific if they are going to get serious about corals. Many corals live in mutually exclusive habitats (like Acropora listeri which is found only on upper reef slopes exposed to strong wave action compared to A. horrida which is found only in turbid water around fringing reefs compared to A. tortuosa found in lagoons) and so far Veron's books are the best I've come across for helping to determine a species environmental preferences. (They may often hear various species of coral lumped together as "SPS" or "LPS" or "softies" which have no scientific validity and no releavance regarding husbandry.) The relationship between pH, Alkalinity and calcium is critical for aquarists to understand and Randy Farley Holmes articles on the subject are the best in my opinion starting here: http://www.advancedaquarist.com/2002/11/chemistry The below links to the research by Feldman, et al, on activated carbon (GAC) skimming, skimate analysis, total organic carbon (TOC) and bacterial counts in reef systems I feel are important also. http://www.advancedaquarist.com/2008/1/aafeature1 http://www.advancedaquarist.com/2008/2/aafeature1 http://www.advancedaquarist.com/2008/8/aafeature3 http://www.advancedaquarist.com/2008/9/aafeature2 http://www.advancedaquarist.com/2009/1/aafeature2 http://www.advancedaquarist.com/2010/1/aafeature http://www.advancedaquarist.com/2010/2/aafeature http://www.advancedaquarist.com/2011/3/aafeature 2 Quote Link to comment Share on other sites More sharing options...
