Amazon measurements are usually including the box
Quick Recommendation on Return Pump

I saw the same dimensions on Amazon, and I found some dimensions somewhere else that were different (smaller) than what Amazon said. The Amazon dimensions were probably the box that it shipped in, as the pump is smaller than that. I'll try to remember to grab some quick measurements when I get home today and will post them up for you.
As far as my review of the pump, I'm really impressed with it so far. It is super quiet, the soft-start feature is really nice. I really cannot hear the pump at all, and compared to my Quiet One 4000 pump I had been running since I setup my tank 2+ years ago, it is COMPLETELY SILENT. To be fair, I've heard plenty of people say the quiet one pumps are silent too, although mine was used it was NEVER silent (far from it). I had gotten used to the noise it made, so when I installed my Deepwater pump, I was really amazed at how quiet it was.

Hopefully this helps I have the BL DC 12 I cannot attest to its performance because I have not installed it yet but I did take physical measurements of the pump
This is smaller than my waveline 10000 in my reef tank so far I am impressed keep in mind the box has to contain the driver and controller so Amazon is dimensions are large

Thank you guys very much for taking the time on this, this definitely helps a lot, go figure I even sent out a request to Marrine Deppot about the dimensions and they gave the same ones from Amazon. By looking at your pictures this pump should work for me no problem. Are you planning to use a strainer on the intake side? Did you find one that will work?
Thanks again.
Thanks again.

I like using 90's with one male thread on the side so I can point the intake down lower in case sump level goes low less chance of burning up the pump

So a couple notes on this, since I'm using mine already. The 90° fittings that I could find all put the intake way too close to the bottom, and it would not get enough flow. The manual recommends not doing this as well. Reason being, if the water level got that low, the pump would not be submerged and could overheat. Even though there is water flowing through the pump, the way the manual reads is that this isn't enough and could trigger the low water cutoff.
Also, I did not take my pump out, but tried to get close dimensions from inside the sump. After seeing the pictures above, the BLDC5 appears to be the exact size of the one tcarter posted above.
@tcarter1936 - I've always used 90° fittings before now, but currently I'm just running my return section water level a little higher. Have you done this successfully on this pump? Just curious, as a way to further prevent microbubbles.

I simply cut the other end shorter on my miter saw. The goal was never to run a low water level, just a precaution I haven't really needed

Gotcha - I thought about doing that, but didn't get a vortex sucking water @ my "low" water level, so I didn't worry too much about it. I may try it though as my sump does have a little turbulence at my weir that creates some microbubbles. That may be an easy way to prevent them. Thanks for the reply!

Same situation here when I upgraded my skimmer to a Tunze......skimmer pump went from I think 70 watts to 15 watts. All was well until deep into winter when a cold snap hit, I noticed the tank temp dropping slowly. Ordinarily the temp doesn't move at all. I added two 100w heaters to compensate for my upgrade.
Thankfully I didn't do that for the power savings either.

It that pump submersible only, or is it supposed to be able to run externally?
Curious since the ecotech clone apparently has a big thread about overheating when run external.
