potatocouch Posted August 25, 2014 Share Posted August 25, 2014 Have you used this in your tank life? Do you like it or hate it? Do you have any issue running this as a return pump back to your DT? Does it struggle on the over head? I am considering to purchase one but unsure whether I should go with more expensive brand such as Eheim Compact+ 2000. LFS suggested Eden 135 pump. Link to comment
Speaker73 Posted August 25, 2014 Share Posted August 25, 2014 I have a DC 6000 as my return on my 50 gallon and haven't had any issues with it but the forums abound with reliability issues. I do want to say that the listed flow rates seem to be a bit high from the actual rates but I have no empirical proof of that other than guesstimates. I an looking at the Fluval SP4 as a return pump to replace my DC6000 if it ever gives out. Link to comment
jedimasterben Posted August 25, 2014 Share Posted August 25, 2014 I haven't had any issues out of my DC-6000. Super quiet and strong. I also have a DC-3000 that was for another project that got scrapped. Link to comment

Based on your guesstimates, would you say the actual rates is 250 gallons/hr lower than the listed flow rates? Link to comment

Halo_003 Posted August 26, 2014 Share Posted August 26, 2014 Was looking at this pump for my 20L actually. Would it be too much though? (I assume yes) Link to comment

disaster999 Posted August 26, 2014 Share Posted August 26, 2014 well since its controllable just run it at the lowest setting. Link to comment
Chris! Posted August 26, 2014 Share Posted August 26, 2014 I haven't had any issues out of my DC-6000. Super quiet and strong. I also have a DC-3000 that was for another project that got scrapped. I have a dc-6000 as well... accounting for head loss and it running my diy biopellet reactor I would say flow is pretty close to as stated, and it has been running for 6 months on a ~ 150g system as a return pump.... just ordered another for another similar set up I am setting up. Thing is silent! Link to comment

Thing is silent! Yep, I measured mine and it is within 5% of what I calculate it should be after head loss, so its within tolerance. Link to comment
Speaker73 Posted August 26, 2014 Share Posted August 26, 2014 Darn it. That's right. Forgot about head loss and running three reactors off it thru a manifold. Ignore my earlier post. Link to comment
jmorriso001 Posted August 26, 2014 Share Posted August 26, 2014 I own a larger one, it works flawlessly, and is quite, energy efficient too if I'm not mistaken. Link to comment

potatocouch Posted August 26, 2014 Author Share Posted August 26, 2014 So it looks like Jebao pumps, either DC3000 or DC6000 is quiet and the flow rate is as per stated in the specs. Just hope that the production batch is good (QA). No one mentioned about heat ... Does it (Jebao DC pumps) generate quite amount of heat? Link to comment
jedimasterben Posted August 26, 2014 Share Posted August 26, 2014 Heat generated in watts is equal to the power draw in watts. My DC-6000 uses 26w power at 2/3 strength. Link to comment

I can touch mine and its not bad at all, alot cooler then I expected. I run it on setting 4, I forget what the breakdown % is on that but yeah, it gets the job done. Link to comment

No it isn't It wouldn't pump at all if all of the wattage was being wasted by heat. They do have devices like that, they are called toasters. Maybe I should be the new LED World Dominator.

That energy has to go somewhere, it cannot just be 'used up'. Would you like to explain where it goes? Link to comment

bdevillier19 Posted August 27, 2014 Share Posted August 27, 2014 The skimmers impeller spins it into the air duh. Damn Ben you're slackin LOL And then when the bubbles pop in the skimmer the energy is released back into the air. Lol. Link to comment
Chris! Posted August 27, 2014 Share Posted August 27, 2014 And then when the bubbles pop in the skimmer the energy is released back into the air. Lol. EXACTLY! And then when we breath around them, we suck in the energy and that is how we get through the day, and life. Link to comment

They do have devices like that, they are called toasters. Maybe I should be the new LED World Dominator. Toasters are basically large resistors hence being called resistive heaters. Motors use large coils of copper wire which act like inductors and resistors. Resistors consume electric energy and convert it into heat. The inductance of the coil is used to create a magnetic field which in turn moves the impeller. Inductance does not consume energy, only resistance does that. Therefore you are wrong and Ben is still right. If you do not believe me, look up how motors work, inductance, and resistance. Also, the pressure on the impeller blades is what cause the power draw. If the liquid viscosity is increased, it would cause the motor to pull more current until reaching the stall torque at which point the motor ceases to turn and just pulls more and more current until the coil burns out. Edit: Also, LEDs are not linear elements, aka resistors, inductors, or capacitors. So having knowledge about resistors would not really help in the realm of LED devices. Link to comment

Not really worth arguing with them. Check out their other posts they've made so far. Link to comment
