Sanjay,

No one responded to your question about the space requirements of the Dart pump. Although I don't have this particular Sequence pump, the motor frames are comparable. I estimate that you will need 30 inches to accommodate the pump, fittings and ventilation space.

asnatlas Oops, I didn't see that!! :o

Thats a big box of fittings ! :eek:

Greg,

Thanks. Those pumps + fittings do take up a lot of space. May be I can put in a bigger intake from the sump, put in a 90 and run the pump+ fittings parallel to the sump.

How wide are these pumps ?

I am seriously rethinking the closed loops now. The cost of the pump + true union ball valves + fittings is not too far from a Tunze stream or a Vortec pump. I will get about the same amount of flow at less than 1/3 the electricity. !! with no ugly plumbing and 35 lb pumps to hide and mount.

Sanjay, the Sequence Pump (MDMC Inc.) web site has all the measurements of each pump they make. It is a great source for researching specs. on a variety of pumps and very useful when comparing to other brands as well.

Seriously though, I am going all Vortech for display flow. Not just to save on electricity but to also allow me to move the pumps around as well as giving a higher level of safety. Lets say you have a pump malfunction. Would you want it to be a Hammerhead driving a 4-way to returns, or one of 4 Vortechs? What about when the power goes out? That is a real rpobelm where I live, and even if Eco-Tech doesn't produce the battery backup as is the current plan, I can always use a UPS to drive the Vortechs and maintain flow.

I use a Sequence pump for my return, and I will use one to drive my NW skimmer, but either one of those can go down temporarily and not crash the system. I realize that upfront cost is steep, but they will pay for themselves rather quickly.

Jnarowe,
Any reason you'd choose the vortech over the tunze?

Well that's a good question. Primarily because I don't like the way the Tunze look inside the tank and I don't want any wires in the water. Also, it really gripes me that they charge extra for magnet mounts.

I am also a bit partial to American companies I suppose. I think the Tunze performance is good but I think the Vortech is a better value.

IceCap is going to charge extra for the battery backup...

Just another idea if you decide to go with the Streams.
Have Will build a little partition out of smoked glass in your tank to hide them.

Great Idea. ANd I love the wood on the stand! :)

wow that tank it insane lol

hey Mantis! That tank has been up and running for quite a while. got any recent pics?

Unless I am missing something at that web site, I did not find the dimensions for the Sequence Dart.

I too am planning on just using the 2 Darts for circulation, feeding the chiller, etc. The size of the pump and the large size plumbing requirements and space requirements makes it a less attractive option for anything else.

You know I went back and looked and I can't find it either. Sorry! I know I saw it somehwere though. I'll check my links and see if i can find it again. Also, you could PM SPAZZ since he has one and can measure it for you. I only have a 4300 and a Hammerhead so my measurements wouldn't be exact.

It seems to me you should have enough room with that big tank room you have, but I understand why you want to know.

Found it on the customaquatic site:

"Cost effective dimensions: 7 inches long by 6.57 inches wide by 11 inches long."

But that sounds a little confusing to me.

Take over half the garage already... your wife will never notice:rolleyes: . You could say she has the option of losing part of the garage or the bedroom next door:)

Ohh.. I wrote first time in Cirilc code page , sorry, so the question for mantis, off topic, I wish you can provide a link from a tank you show.

Sanjay, are you using sketchup for those 3d drawings if so id like to ask how your posting them, I am trying to post a drawing on a local forum and I cant find a online file host for skp. files and thus havent been able to post the pics.......ovcourse if your not using sketchup then just void this message.....btw....things are looking good and I cant wait to see the tank full!!

Thanks

Jordan

No, i used Pro Engineer for the models. Saved them as JPEG files and host them on my website.

sanjay.

Ok thanks anyways, i guess back to the drawing board

Sanjay, sorry for the hijack

The clam in the distance is 14 inches long.

What are those two angels that you have in there?
Do they bother your corals?

why did you put your clam in the back of the tank? Can you see it back ther?

-alien

It's not in the back of the tank...

The clam is located on the "left" side of the tank (above the built in bookshelf)...

I just love Mantis' tank, can never get enough of pics of the display & equipment ... sorry Sanjay ... just had to say that ... I'll return to lurking now ... I am enjoying watch your system develop as well :)
