Guest Bemmer March 28, 2006 March 28, 2006 Hi, I am working on setting up a 270g (72 x 36 x 24H) FOWLR tank and I am trying to figure out the water movement setup for this tank. I understand that the water movement on a fish-only tank is not as critical as a reef tank but I want enough flow to move around any detrius and fish waste up to the Calfo-style horizontal overflow trough. So, what do you have or what would you do if you were me? Drill four holes for a closed loop with a 4-way OM system or purchase two 6200 Tunzes and a controller. I have not priced them but I believe they are close in price. Looking for the best way to move the water. Thanks for your input.
dhoch March 28, 2006 March 28, 2006 Rebecca, I can't say anything about the squirts (I don't have one), but I do have 2 streams and as water movement goes I really like them... In particular I like the broad flow not narrow flow of the streams (plust the flexibility in porgramming). Dave
flowerseller March 28, 2006 March 28, 2006 I have been using Tunze streams since they came out. They are great, however, in a calcium enriched environment, they need to be maintained to get full flow. Well worth a soak and run in vinegar a couple times a year. Get either the magnet holders, or make a custom bracket to mount well.
Eve March 28, 2006 March 28, 2006 Don't know anyone using one now - but the OM's seem to need a lot of room and use a lot of PVC
mutley29 March 28, 2006 March 28, 2006 4-ways rock The plumbing can be a bit tricky, although i think it is just me I suppose it all depends on how much work you want to under take, i'm glad i went with 4-way over streams, not only because of cost, they are well made, less cabling in/around tank, ruins the clean look of the tank and the after sales service is excellent as is before sales. The 4-way is about $340 after shipping i think, sorry bad memory, and i may be wrong, and probably am (my PC connection at work is slower than dial up so got bored of searching) but my first try at a 6200 came up on Premium Aquatics at $451 Although everyone i know that has them says they kick arse, but for that price they should Check out the Oceans Motions Forum & Water Pix for ideas and suggestions.

Gatortailale March 28, 2006 March 28, 2006 For CL with a OM 4-way you are looking at $300+ and another $200+ for a good pump and 100+ for plumbing = $600ish For 2 tunze's with controler you are at $700-800 with mags I think My short experience haveing both on my new 215, I would go for tunze's. Less to fuss with and no worries of bulkheads leaking ... & get a much wider flow the way the tunze spreads out vs. concentration of a CL outlet noz. HTH,
ErikS March 28, 2006 March 28, 2006 Both? I use both streams & a CL. In truth, if I had it to do over I'd likely use the streams - just more energy efficient. They are pretty big & ugly though.
dzekunoi March 28, 2006 March 28, 2006 I'm dealing with the same dilemma. :( But 20% OM group buy on RC made my mind. I think you can not go wrong with any. The only thing I did not like about getting Tunze - I do not like how they look in tanks, fairly bulky. If you hide your OM all you see in the tank are nozzles.
Guest Bemmer March 28, 2006 March 28, 2006 dzekunoi, I wish I would have seen the thread on the OM group buy last week. I sent them a PM in hopes that I might be able to get in on the group buy but have not heard back yet. Anyway, currently I have the Tunze 6200's w/controller AND the 4-way OM on my new reef system. It is not completed yet so I have not seen either one in action. I figured since this tank will be a FOWLR the 4-way OM would work just fine. I don't need the full turbulence that the Tunze's can give off in a tank.
traveller7 March 30, 2006 March 30, 2006 IMHO: Tunze's first so they can be run on back up power incase of disaster...then the OM on return line.
londonloco April 1, 2006 April 1, 2006 Check this out: http://www.ecotechmarine.com/products/vort...tteryBackup.htm and then the long thread on reefcentral: http://www.reefcentral.com/forums/showthre...threadid=672444 I'm considering one for my 120G, but not sure if it's "too much" for a 4ft tank....
Guest Bemmer April 3, 2006 April 3, 2006 londonloco, Thank you so much for sharing these links. I spent the last hour reading about these Vortex pumps. I am very interested. Another possible option. R-
