Turbelle 3000/2

[InsaneClownFish]

Roger, thanks for your responses regarding the 43 gallon L shaped tank I was initially going to setup. However, this plan has changed an I'll be ordering a 40 Gallon AGA breeder on Sunday.

This tanks dimensions are 36x18x16(high). I want to use somewhere between 80- 100 lbs. of live rock and a 4-4.5 inch southdown dsb.

I realize after receiving your reponse regarding the original setup that a stream would be too large for this tank.

I am however looking at Tunze again because I want ONE powerhead that will provide all of my constant flow needs, so I'm now considering just a 3000/2.

Will the 3000/2 reach the other side of a 3 foot tank?
Are these identical to the electronic pumps with the exception of wave making ability/multicontrolling?
Do these pumps have the same run dry protection as the eletronic ones(and how does this work)?
I've seen a few pictures of these pumps mounted partially above the water line, so I'm a bit confused about how they should be mounted. Is this just one option? Are they 100% submersible(this was my initial understanding, and that they are water cooled)? Is the cord insulated for proper submersion?
I read somewhere that these 3000/2 might actually be underrated and may surge to 1000gph- is this true?
Forgive my ignorance as I haven't ever seen one of these pumps up close, or in action, but what is the long green cylindrical extension protruding from the botttom of these pumps? I'm assuming it's the water intake. If so aprox. how long is this piece, and how much distance does it require from sand/live rock? Is there any type of prefilter or paraphanalia that prevents the pump from clogging...or small aquaria from destroying themselves/the pump?
For the outlet, if placed a few inches from live rock will the flow successfully spread around the live rock, or must the powerhead be placed above/behind the rock?
Are these units also compatible with the magnets?
Are there any innovations within these pumps which would make them less susceptible to the effects of heavier calcium concentrations in the water(the reason I am NOT looking at SEIOS)?
Do they require any special maintanance? What is the normal maintanance routine you would recommend?

Where can I buy a 3000/2? Your three online venders don't list them on their sites.
Thanks for your patience... :rollface:

The 3000/2 has a flow pattern that is about 5ft long and flares out to about 12" around, figuring the bounce back I think it should meet your needs.

They are identical in basic drive unit and construction but it stops their. Their is no run dry protection- that requires the electronics. They cannot be turned off and on more than once an hour- no wavemakers.

The pumps are submersible and water cooled but they can stick out slightly and run fine. The cord is a grounded cord with PVC double insulation, it excedes the standards.

I think 792 gph is pretty accurate.

The green cylinder is the intake screen, it is big to diffuse the intake and handle the intake capabilities of the pump. It is about 7" with the coupler required to attach it to the pump. Their are easily a dozen filter options and intake options available from very fine prefilters to cartridges for carbons and phosphate removers.

They are compatibe with the magnet holders.

Our pumps use the least electricity of anyones, the 3000/2 uses 23W. The power consumption translates to low heat production. Heat and vacuum are what precipitate calcium by degassing CO2. On the downside, they have very tight tolerances to get that level of efficiency and they cannot handle alot of buildup. I would still not go crazy, you do not want to be running 500 ppm and 12KH, just keep good constant levels, 380-420ppm and 10-12KH and you can clean them every 6 months but I would clean them the first time aat 3 months and if you do run high levels you will have to clean them every 2-3 months, fine sand can also cause them to lock up so any sandstorms mean- clean the pump.

I have some on the way, no one stocks the 3000/2 except a couple LFS's. I can get it to you though just place an order with the vendor of your choice and I will arrange it. They are out of stock but already on their way to me.

Roger, do the dozen intake options come with the intake screen?
How far must the bottom of the intake be from a very fine sand bed, and is the 7 inches in addition to the length of the pump...so this would be aprox 10.5 inches in total length- that would only leave about 1 inch between the intake and the sand bed.....16 inch tall tank...4-4.5 inch dsb....any thoughts?

Thanks for your time and quick response. This pumps sounds perfect, but I want to make sure it's not going to mess with the sand bed...

Maybe there is a shorter diffuser?

Thanks! John

 

[rvitko]

Yes, about 10.5" total height, the intake is very diffuse so I doubt it would take in sand if it was an 1" above the sand, the prupose of the big intake is to make it safer, it isn't perfect but it is less likely to suck a fish in with such a big intake area. Their is a shorter diffuser but they are for smaller models of pump and it will limit the performance after they get a bit dirty and grown over.

 

[InsaneClownFish]

Roger, thanks for all the help, can these be mounted side ways with the magnet holder- so that the intake is parrallel to the tank top?

Thanks John

 

[rvitko]

Yeah, you could but I think the flow is better if the intake takes water from low in the tank.

 

[InsaneClownFish]

Roger, sounds good. If I have an issue I'll probably mount it on a slight diagonal. I'll probably be placing the order with Premium Aquatics some time this week...so I'll keep you posted..

I'd also like to get the magnet holder if those are available yet.

 

[rvitko]

We are really behind on magnet holders.

Roger,

Can they be used for a closed loop? I have 2x3/4" Sea Swirls and I was considering a closed loop with them. It seems that the 3000/2 might be a good match for the SS which handle 850gph. If I can plumb them into a CL and lose maybe 50gph to pipe friction and bends - just a guess - I can run approx. 750gph at 22w through a SS which helps to increase the directional flow. Double the setup and I can run 1500gph through 2 SS at 44w. It seems that their low head and high energy efficiency would make them a perfect pump for a CL.. Must the 3000/2 run submerged? if so I can place them in my sump and run the CL from there?

The pump is not rated for head pressure. The only pump we offer that could pump near tha much with any back pressure is the 1073.04
