I just realized that they won't work on anything I own since all the glass on my tank and sump is 5/8 thick, so you might be on. I was hoping to use them to add extra flow to my water change and frag chambers, but the dry side just falls right off

I've got one of the original MP40's. It's a good pump, lined up as perfectly as possible, but since day 1 it's been noisy. Flows a ton of water, random flow is nice, but I just can't get over the noise in my living room. Bzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz

I've started looking at my replacement options.

So to me it sounds like other than noise, the reason people are selling them is mainly because a lot of people own them now and it's only natural for more to be for sale as more people adopt them in the market.

When I looked at Vortech vs. Tunze I found a lot of complaints (here and on RC) about noise, but also reliability (as fishytime mentioned). The common thread was most people seemed to like the performance but were shocked by the amount of noise vortechs produced and the amount of tinkering required (even on working models).

I went with Tunze and have never looked back, I've had a power supply fail on a 5 year old 6055 and that's been the only issue out of 2 6055s, a 6045, 6025 and Tunze Wavebox. All are/were dead silent and set and forget.

Tunze 6105 for 3 years and no issues(hardly audible), MP10 1 year also no issues(excpet for noise). I almost traded my tunze with MP40's but I heard my buddy Peter's so call symphony of the Vertech pumps and instantly changed my mind.

i once turned off my mp40s for a few hours and it felt so weird.

once you get used to the noise, you dont notice it as much.

I don't really hear mine. I have it at about 70%. Not in pulse though.

I've never had a Tunze so I can't really compare but I think Vortechs are awesome and well worth the money. I could certainly never imagine going back to Koralia. They're like putting footballs in your display tank!
Like some of the others here though - I think I just got used to the noise. That, or maybe its because my living room (where my tank is) is so rarely anywhere near silent anyhow.
