I think it might be the little flat thingy on the outlet.

i have a 55 gallon and i use a mj1200 and 2 mj600 and i get really good flow.

Big Als has them and I have seen them at Pauls Aquarium in Surrey. They are a separate attachment that can go on powerheads or even returns. They look like a miniature version of the Tunze stream front and they revolve 360 degrees. THEY are not the little flat piece that come with the maxijets.
Hydor is the manufacturers name

I mucked around with the bio flos on my return lines when I setup my new tank, I wasn't really impressed. I found them difficult to attach to the pvc and they blocked a lot of light. I also broke one of them somehow, broke a tooth off one of the gears, I have no idea how.

However in my 12 gal I stuck one on the end of my powerhead because my anemone wouldn't settle down. It takes up a big amount of space still but it did get the anemone to relax.

I don't think I'd recommend them to most people though, by the time you get a maxijet and the flo you are about $5 shy of a sieo and have nowhere as useful. That wide output on the sieo is very effective.

I have 2 620's in my 40, and if the chance came up I would swap them out for a pair of 820's. More flow the merrier. They do have flow restrictors on them, so if you did go with 820's and found it to be too much, you could slow it down a bit.

yeah, im leaning towards two 820s or 1 820 and one of the larger ones.

i might get a chance to upgrade tank sizes to a 75 gallon once we're done renovations.

would that setup work for a 75gallon if i got a chance to upgrade?

if you are good at DIY, make a Maxi-stream. Its basicly a tunze but all you do is buy a MJ-1200 and some extra parts, maybe 10$ worth. And you have something that blows the tunzes away.

I've made a few, amazing things for next to nothing.

Take a look at this thread, its a great resource to build one of these.

damn that is a long thread...... split 4 times after 40 pages per split........ great info.....

Care to summarize for us? :mrgreen:

I have lots of maxijets kicking around I could play around with. I read that thead a long time ago, but wasn't sure where to get the propellers.

I got mine from BA online (cheaper than in store, go figure):

They fit perfectly onto my 3/4" round nozzle loc-line on my return. They're cheap and effective.
