Tunze VS VOTECH

ok gust some comparison, I know there is some data telling Tunze is below there reading, however I have to agree with what the video shows.

the Tunze is more under pressure vs vortech, resulting the tunze pumps whatever flow thy have, clearly shows that that flow makes it to the other side of the tank.

the votech on the other hand has more flow as thy claim, but this flow shows clearly to disappear as soon as it gets resistance from present water in the tank.

comparing it with a needle ore a stump point, I know what makes it further into something.

thing is that compare it with a long thick rod (the stream of the tunze) all the surface of that rod is moving one direction, creating friction with the surrounding.

meaning that if the pump is rated for 2000 gph, it in fact can move much more, because the stream itself creates friction / turbulence

the vortech next to it is the stump point that looses its power under its own power, and as a stump stick in the grown, it will go in, but only if you keep pushing, ore in other words, the votech needs to run longer to mix a tank than a Tunze douse.

for the information, I don't have a tunze nor a votech, I don't criticize any findings, but this at this time is how I would se the entire comparison

I have expressed my concerns on this test on reefcentral. The equipment used for the test was not appropriate. Further more, they did not eliminate a number of uncertainties that they equipment used will provide.

Sorry, I posted before I read your link. I was referring to a different study (the one put on using the FlowTracker as the measuring device).

pretty interesting stuff......well not really but good to know....sort of.

Tunze or Vortech....you cant go wrong with these pumps. Myself I prefer the Tunze pumps but that's just me.

I don't care about any tests..going to have to try to pry my vortechs out of my hands.

No thanks...
got mine full of tunze's

You can get the programmer for the tunze too.

I have tunze right now, but did have an mp40 for a couple days, I got real tired of it sounding like I left the vacuum on in the other room.

Ha Ha. I dont find my Vortech loud or bothersome as far as noise goes. Probably too many concerts and hours with the headphones on....

after reading all the responses Im glad so many people realize the value of a quality pump and lets face it both vortech and tunze put out a great product IMO.

Curious on the up keep of vortech? I usually go a year before cleanings on my Tunze's.
