DC water pumps

Been using jebao/jecod for the last 3 years I would say. Currently have 5 reef tanks running them ranging from 30 gallon frag tank to 210 gallon display tanks. Great pumps for the money. Surprisingly well built as none of them have failed me yet. I have backups just in case.
 
I've been using DC for about 4 years now. But whether I'd recommend DC depends on what you want to accomplish. I love my L1 but would not have purchased it for external, it has no fan or heat sinks. I like most people with AC pumps put in a manifold and choked it down to the flow I wanted for my tank. This throws away a bunch of energy and puts unnecessary heat in the water. This is why I switched to DC, my 1st pump waveline and 2nd pump RODC 5500 were made in China, no complaints but I have read some from others. I mainly upgraded to the L1 for maintenance, I over fill the sump and run about 2600goh to my 150 when I stir up the bottom, then crank it back down to about 1250gph after it clears up, replace the sock and drain about 2 gallons from the sump.

I got in a couple of pretty heated engineering debates on RC, a few good engineer guys chimed in and a few less savvy folks jumped in to defend their wives tales. Anyhow if you search for AC vs DC you can see some pretty interesting actual test cases, you just have to look past the non factual contributors.

I'm using a Jebao DC6000 and like it for the most part.
Pros:
Reasonably priced.
Adjustable with 6 speeds
Feed mode and auto-restart
Soft start and ramps to set point
Fairly quiet

Cons:
Feed mode shuts the pump completely off and water flows back into sump - higher end pumps (vectra L1) ramp down to the point where the water nearly stops flowing, down to a trickle, to maintain the same water level in sump - but remember this pump costs 75% less than the L1
Not completely silent - silence is golden for me

As far as long term reliability, hard to say. I picked this one up second hand and the seller had another of the same model that had failed, so they do break. I think having a spare pump is good practice regardless.

I run a dc12000 and only run up to 2nd setting because it would empty out my sump before my tank drains into the overflow causing and overflowed.As for the feed stop comment.Yes this is with all power interuptions or manual stops.So, a failsafe inplace stops water to flow into the sump when power is lost or feed mode.Stopoing the siphon at the return line like a small drilled hole to achive this and maintaining water in the tank at desirable height. Thus when the pump is started it will overflow and go into the sump.My tank water lvl only drops about 1/4 when the pump is stopped

Also the dc12000 in my opinion runs silent

I used waveline and swapped it out for Vectra M1, swapped my reeflo hammerhead for L1. Silent and couldn't be happier
