pweesng Posted January 27, 2010 Share Posted January 27, 2010 Hi Guys, Need some help. My tank is an approximately 300 litres tank (Main and sump). Currently the return pump is an Ehiem 1262 which should be aroudn 3000 litres / hour before headloss. the flow returning to the main tank is too strong. The difference between a wave maker and the return pipe is that the return pipe is a lot more concerntrated and forceful. This resulted to current at the front of the tank being too strong (IMHO). The fishes are struggling to keep themselves at the same spot. I am curious why they are not hiding in the caves and shelter created by the live rocks. But if i want to reduce the current but not slow down the turnover rate for the return pump. Is there a "return pipe" diffuser that i can use, so that the current from the return pipe is more uniform or more diffused? Thanks for any advise thatis forecoming.

SRC Member onizukaa Posted January 27, 2010 SRC Member Share Posted January 27, 2010 what i can suggest is to put a T joint on your return to "seperate the output into 2" therefore reducing it by half Quote Link to comment Share on other sites More sharing options...
Moderators thomas_lim Posted January 27, 2010 Moderators Share Posted January 27, 2010 Bro onizuka suggestion is good. Coz it may cost u more harm than good by restricting the flow of the pump. It mean more back pressure on your pump and may lead to a hotter pump and shorter lifespan. Quote Tom Link to comment Share on other sites More sharing options...

SRC Member digibee Posted January 27, 2010 SRC Member Share Posted January 27, 2010 Hi, mine is eheim 1260 pump for my 2 ft cube tank. The return flow is just nice and gentle. Yes, I have a T joint that split the return into two sides. Quote () Happy will do ... (o_o) Link to comment Share on other sites More sharing options...
FuEl Posted January 27, 2010 Share Posted January 27, 2010 Why not just change the pump to a 1260? I got a 1260 which I don't mind swapping.

Solo77 Posted January 27, 2010 Share Posted January 27, 2010 Face your return to one side of the glass, use rocks to diffuse the flow or drill holes at the return..help to reduce the flow and also act as a safety feature to prevent back flow. Take it as reference and need confirmation from more snr reefers. Hi, mine is eheim 1260 pump for my 2 ft cube tank.The return flow is just nice and gentle.

SRC Member tian1974 Posted January 27, 2010 SRC Member Share Posted January 27, 2010 i am using eheim1262 and drill a hole by the side of the return, and though can see the flow is strong, but my fishes can swim from left to right and hide. even my small nemo can swinging around. maybe i should consider a y-joint and see how Quote God Blessed all who appreciate His wonderful and beautiful creations. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ my first reef aquarium 15jan2010 3x2x2ft EOS 10mm tank with sump//deltec sc2060 skimmer//arctica 1/10hp chiller maxpect g2 170w led//vortech mp40w wavemaker//eheim 1262 universal pump eheim compact+ 3000 chiller pump//caribsea ocean direct live sands 40lbs and other misc...

pweesng Posted January 27, 2010 Author Share Posted January 27, 2010 Thanks to all, I shall go grab a T or Y joint. I assumed it can be found in C328? I am reluntant to change the pump because at this point of time, i gather the turnover for the tank is probably about 9 to 10 times per hour. If i change the pump to help the current, i might inadvertedly create another one next time. Thanks again.... Quote Link to comment Share on other sites More sharing options...

Thanks LaW, Actually i was looking at it, but i am not sure how it works, and from what i read, there wil definitely be some restriction in the flow... have you used one before? can review?

SRC Member teebs Posted January 28, 2010 SRC Member Share Posted January 28, 2010 hee hee... thanks... will have to check it when i get home... office blocks all streaming videos... Basically what a SCWD does is that is alternates the flow between the two pipes that it is connected to. How fast it alternates depends on the incoming flow. It actually works like a wavemaker providing alternating linear flows to your aquarium.

pweesng Posted February 2, 2010 Author Share Posted February 2, 2010 Only Reef Depot has this product. You can go there to take a look. Hi Peter, Thanks for the advice. I was at ReefDepot over lunch. The SCWD idea, although woudl have been a perfect solution, it won't work. The SCWD is supposed to be sitting on the floor of the tank, directly connected from the Return pipe. unfortunately my return pipe is all the way up at the top of the tank. Coupled with that, the device is also too heavy to be hanging in the middle of the tank. Will have to resort to other methods, such as a T or Y split.
