Not to sound rude. please dont take this as a attack . just stating a fact.

Nope that isnt true. please show me one example .. and going from a 40 gal to a 80 gal isnt considered a actual upgrade.

If you are stating that a increase of 80 gal tank to a 120 gal tank maybe a bit but not alot.

If you are stating that a upgrade from 80 gal to a 200 gal nope you wont see it happeneing.

Agree this is why we have not rushed into the DC range yet. we will of course supply on demand, but lets see what comes.

I spoke at length with Bubble magus late last night and right now they are releasing no details at all. What was seen was a "thought in motion" rather than a pre production test.

No doubt these products will arrive, but I am not hearing any time soon.

No worries, I appreciate your response and feedback. I have never used or owned a variable DC pump. How is going from a 40 gallon system to a 80 not an upgrade?

Higher the pump is turned up the more water and air it would draw, therefore skimming harder if I understand them correctly.

From what I understand the body size and pump match so your debris ends up in the cup. Not just collecting in the neck. So a large skimmer turned down seems to me that it's not a effecient device. Some think you can't have to big of a skimmer I think otherwise.

I am one of thoes, but there is a differance between running a large skimmer on a small tank and running a large skimmer that has been turned down on a small tank.

i don't think the purpose of having a VDC pump would be for upgradability (and yes going from a 40 to a 80 is a upgrade) but rather for fine tuning, and also some power savings.
