Which Powerheads are considered "the Best"?

[TheReefGeek]

As for one or two, I would go with two smaller seio's, one in each back corner pointing upward towards the middle top, intersecting each other, for turbulent flow.

so maybe 2 Seio 620s or 820s??

620s probaby?

i assume the number is the GPH rating or something...possibly...maybe... lol

[TheReefGeek]

Yes, 2 620s would be awesome flow for your tank.

I've got two Seio 620's in my 55 gallon and am very happy with them so far.

A friend of mine is using mj-1200's with those Hydor diffusers on them.....very cool and creates alot of mixed flow

What's a Hydor diffuser look like? Sorry, I guess I should know this, I just don't remember and I didn't find any useful hits in the 10 seconds I alloted myself to google it.

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

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.
