You will get a consistent output from an AC pump. Some people don't seem to experience this issue - I've seen it myself, a lot. I no longer use DC pumps for returns on siphon-style drains.

Explained very well, had same issues with controllable pumps

Default Thanks

Guys thanks for the ton of responses

This forum is awesome.

It almost looks like AC pumps are outdated and most companies are not putting money into them anymore.

DC could be a risk but I think I may be leaning towards that side of the fence.

Jabeo, ecotech, reef octopus, and the new core look pretty great.

I wouldn't say AC is outdated;
More like tested old technology.

While the tech may not change, it still has its place.
For example I need an AC return pump because DC cannot handle the pressure of my system.

And that's a blanket statement, there might be a DC option for me but if I recall correctly, that option would also cost thousands more.

Had a Dart as a CL pump so directly below tank. Quiet but far from silent, still okay for the living room with the TV on.

I still have a brand new, unused Blueline T4 kicking around for sale. Never ran it but everything I read on it said really quiet.

Nah, it's just about consumers wanting something new and fancy. I don't buy into new and fancy. I like tried and true. I have no use for a controllable return pump (or skimmer pump). I'm all for controllable powerheads though - my Tunzes are all 5-10 years old.

All the European brands are still putting out good quality AC pumps - Eheim, Tunze, Sicce.
