Bypass the controller on a DC pump?

[FishyFishy!]

Well....been a long night. Swapped impellers with the good one, still no change. Runs for about a second then stops.

So.....onto frankenpump! Took the mag24 from my water change setup.....and it was just too much power! ! Drains couldnt keep up. So I swapped in my mag 12 from my manifold. Everything works great!

But.....the big thing here is, if the mag 12 rated at 1200 GPH is about the same flow as the DC10000 return pump (rated at 2640 GPH)....what kind of flow are these DC pumps actually putting out??

Totally rethinking these pumps. I was going to buy a new one. But why? If these are putting out terrible GPH for what they are rated...whats the point? Id rather a $120 workhorse Danner Mag than an adjustable DC that puts out half the GPH rating for double + the money!! Didnt even think about this until I plugged the Mag pumps in and saw the difference in flow.

Anyways... frankenpump system to the frag/fuge system is up and running... but no more manifold pump. So I will have to add some carbon in a media bag somewhere to compinsate.





So brutal! Random pipes everywhere. Lucky i'm a total horder and kept a tonne of random piping around. Also had to make stock piles of RO water for top up because I tried using the top up/water change pump.

OH YEAH...and my RO/DI unit just stopped working....no flow whatsoever. GREAT day in the hobby for me!

I had one of the DC10000 pumps and it did the same thing yours is doing. I called JL Aquatics and they took it back under warranty. Credited me the full amount toward a Reefflo Dart Hybrid. They said something about an issue with the dc pumps.
