what does everyone use to change water movement?

[fungia]

i am trying to redo my water circulation and i want to see what you guys all use, please let me know if you dont like what you are using. if you use more then one please pick the main one. tia

In my new 150 I am going to use three returns, one through a seaswirl and two at the corners returning through 90 d elbows with the wide spout on the end. I am also going to add a tunze stream to one end of the tank and place sps there. I am trying to creat different reef zones in one tank. On the front where the current is blowing strong the forereef and behind the first rock pile the back reef and the second pile of rock will have softer currents and a low flow area like a lagoon down by the sand. Of course these areas will be hard to all create in one tank but will be popualted with different corals according to the flow. I am also placing frags of the same pollciipora in different flow areas to see the different growth patterns of the coral. It should develope thin branching in fast current and thicker more spaced branching in soft currents.

hmm, I use a sqwd on my 5g with a maxijet 1200, works extreemly well.

and a neptune controler on the 75, that too works really well.

You might want to check out www.wave2k.com for another idea too.

What is a better option for you may not be the most popular one. One of the main consideration you need to know is the size of your tank. The appropriate option for a 20 gal is very different from a 600 gal tank.

Hmmm. I never realized so many people used SQWDs here. Neato.

I had a seaswirl too, stupid POS, it finally blew out the motor, when I opened it up, it had rubbed an arc across the case so bad it was almost at the point of cutting threw the plastic. That would not have been good, probably would have caught on fire, or at a minimum blown a fuse.

From the looks of it, the part that rotates was no longer rotating, but the motor was still going strong, and finally died out. I wont be blowing another 200 $ on one of those that's for sure.

In fairness, I voted SQWD but as of the moment I've only got "stagnant" PH's... I'll be moving my tank around a couple times here soon and the 2nd move will be an upgrade to quite a few areas of the tank (including water motion which will include SQWDs..)

If $$ allows, I may also wind up utilizing both SQWD and a PH timer of some sort. This also depends on how I decide to set the tank up on the 2nd move.

I will probably be trying a Tunze Stream (or equivalent DIY) on my 60. I'd try a SQWD, but I'm waiting for a larger diameter option. The current one is 3/4".

Believe it or not, my PowerSweep has been working great for the last 2 years without maintenance.

As a centerpiece on my coffetable, it helps remind me of how MAD I was after buying it. I am now more careful about every decision I make for my reef, and in life.

In all seriousness, I voted for wavemakers and powerheads.

 

[dwall174]

All I have for now is two 3/4" return lines & two powerheads. I do plan on getting a couple of These to run on a closed loop system that I plan to set up on a 90gal tank I plan to set-up this summer.

 

[goshel]

Pardon my ignorance, but what the heck is a SQWD?

 

[Unarce]

You'll find the makers of SCWD here:

There's even a video you can watch.

I'm currently in process of setting up my 180 gallon tank after I moved (will be inwall tank, building fish room now). I was thinking about using two SCWD's on it. The hotty in the video was nice... but what about you ugly folks :wink: do you like your SCWD's? Love to hear how long you've been using them and your results.

I already have a tunze stream lined up. The two SCWD (or more) wil likely be on either a Ampmaster 3000 or Iwaki MD70RLT.

I used SeaSwirls on the old setup and frankly I got tired of mailing them back for repairs. The insides are just to fragile and each time I get the "it's your fault" feeling from SeaSwirl. I'd rather not use them.

Hey Rich,

Do they make anything bigger than 3/4" yet? Last I knew they were only rated up to about 1400 GPH...

Been using a Digital Oceans LightWave for a few years now.

 

[reefland]

Hey Rich,

Do they make anything bigger than 3/4" yet? Last I knew they were only rated up to about 1400 GPH...

I think they are still at 3/4" and thats why I was going to use at least two of them.

 

[ChrisRD]

Some time ago there was talk of a 1" version, but I haven't heard anything lately. Anyone know what the deal is with the larger model? Is it still in the works?

 

[Anonymous]

Can someone please explain to me what makes the Tunze stream pumps so desirable? They seem so popular, but I really don't like powerheads in the tank.

Also, is "turbelle" just another name for these pumps?

 

[liquid]

The Streams are desirable because they produce a LOT of flow for little electrical input. Someone w/ the right tools and some DIY smarts could make something similar if they wanted to. It's essentially an aquarium pump with a boat propellor on the end instead of an impellor.
