Would those work on a Seio? :neutral:

you can get the props at any hobby store.. In fact you can get everything you need there except the pipping. Its really quite simple. And depending on how much flow you want, you can use your 400 , 600, 900 or in my case a 1200.

apparently the 900 is best for watts used vs flow. But I am using the MJ1200 with a 1.75" prop.. the power the comes out of it is unreal. I may need to use a smaller prop cuz its just too much flow for my 50 gal.

The seio already has a difused flow like that, so it would be redundant wouldn't it?

wow! those seios offer a lot of flow.
Where is the point where a lot of flow becomes detrimental?
I have a 75 gal, standard size and was considering 2 seio 800 series.
im currently using 4 aqua clear 201

But it says that these rotate 360 degrees?? Wouldn't that be different from a Seio??

I think the only way flow can become "too much" is if it's harming corals that don't require a high flow. SPS would love it. That's why SPS keepers try to cram in as much flow as possible.

tomini it is difficult to compare the flow from a sieo directly with a classic powerhead like the maxijet. There is more water moving, hence the gph figures but the output is spread across a much lager area. Feels about the same when you stick your hand in there. There is no question that the larger streams are often much better for reef tanks though.

thanks for your imput guys =)

Try to imagine 30 tons of water being displaced every 5 seconds or so... (a SMALL wave in comparison to the big picture), then think of what goes on in our tanks... the powerheads being referred to offer very different flow patterns - the Maxijets almost straight sheer flow, which wouldn't be good if pointed directly at ANY coral. Seio's & Tunze's offer a wider sweeping swirling vortex kind of flow aimed more at volume than being directional, a much more natural "current" solution.

As for the money, you get what you paid for... period, the end. Maxijets are a good value for the $$$ and you can run them on a wavemaker. Seio's move way more water (read FEWER ph's = MORE flow), in a very natural way, again are good value for what they cost but you can't use them on a wavemaker.

Tunze - well, I already said it, you pay, but wow... :surprise: With a six foot tank, they're not too obtrusive, and they are remarkable in what they do. Instead of just steady laminar flow or back & forth like with a wavemaker, these amazing powerheads make my reef come alive. I will have flowing motion one minute, then a gentle pulsing the next before a new flow pattern emerges. Every portion of the tank gets "sloshed" with a good current, and I couldn't imagine being without now. The ones I have are controlled and variable speed, (6100), but there are cheaper ones. Pro's - they're simple, easy to install and provide amazing natural water flow. Cons - Price of course, maybe a little on the big side but something this good has to be built right as well at the prices.
