Tank size question

Im gonna get the custom 180. If im doing the closed loop which i probably am, does that change the number or placement of overflows?
Also, once its set up and running am i stuck with it forever? can i change to powerheads once the tank is full if for some reason i want to?

The CL will be able to shut down if you wish but I don't see why you would ever want to.
Now I'm really confused! Why get a custom built 180? You have one in your town and can just get it drilled with a stand and probably pick up a 100 for a sump/fuge for the same price.
Am I missing something? :notsure:
See now you've got me second guessing.......

For what it will cost me to buy it and get it drilled locally, i wont save that much from the custom. With the custom, i can have the eurobracing and starphire glass. To me its worth the difference i think. Plus thats what my wife wants me to get and shes the boss as usual. For a few hundred more i might as well get the absolute best, thats not alot considering the total $ ill drop into this.
I figured i wouldnt want to change the closed loop but who knows.
Is it that easy to find a place to drill it locally? Its hard enough to find the tank, to find a place that i would trust ti drill it also isnt worth the money id save, at least i dont think so. Ill call around tomorrow and check.

if u want a 180 with starphire that would be awesome! i got mine all done up but i used Lee Mars version of low iron glass called clear view and its flat polished a lil cheaper than starphire but still great quality glass
nothing like a great tank .... i can just tell the quality of all seams and all the beveled corners and such makes the tank

Gotcha! thats cool, check out my signiture I know who runs the show!
Look around for a 125 or a 100 for the sump fuge, Or see if the builder will make one to fit the stand. Then we can do the calc's and such. 2 OF's - 1.5" or 1.25" drains will work nicely and get you good flow through the sump. these should handle 2000gph+. 3" or 4" x 6" OF boxes will do or what ever they suggest. Then we can go another 2000 through the CL. I'm thinking twin mag 24, Now that will move some water!

Isnt that really big for a 180 sump/fuge? 120 or 100? Its gonna be one tank then hopefully? Ive seen some of your sketches of it i think, basically sump-baffles-return pump-fuge, right? I was figuring it would be more like 75, what are the dimensions for a 125 or 100?
You thinking two overflows and 2 CL returns or 3?

Here's what I know, it'sa 180 2-3 years old with factory metal halide canopy, ($1k investment alone there) also power cpmact in lighting.....full wet dry pumps, loads of rock, heavy coraline running system. Stand...Breeding pair of maroon clowns (breed weekly).
Full running set up ready to go... I'd take it myself for the halide alone, He's looking at $1500. Let me know asap.
sent you an email

50 gals will be for the fuge alone the rest will be for a big skimmer and big return pump. Yes it will look like a lot of room but you're putting 2000gph through this thing. Any thing smaller may led to micro bubbles getting back to the tank. Besides the bigger the better more water volume can't hurt anything.
Tim
BTW, I would go look at that tank!

If I'm not mistaken, I think 60"L x 18"W x 21"T is a 100. I think these are standard. I could be wrong though........
So if we cut it in half, one side for the fuge and the other for BIG skimmer, baffles and return pump.......
I would still go look at that tank, sounds like a steal!

I'm gonna try but now at least im excited knowing i can actually probably get this done, well at least ordered by saturday if i dont like this tank.
Would almost rather set up my own system from scratch though. At least have you build mine from scratch i mean.

Sounds like a good size, How many gallons would that "actually" be. Say i have 175lbs of LR and a 3"sand bed. Do you know about how much water that would displace of the 280 between tank and sump?

Nope, very difficult to calc and I see no reason too. You won't have 100 in the sump/fuge b/c you will need to have backwash area for power out situations.
IMHO a 3" sand bed is kinda in between and will really not do much. I would stick with 2" in each MT and fuge. The macro aglae will provide plenty of malnutrient export.
Yes, I hear you on building the tank you want but overall it will be a lot of work and money. I see no reason to start with what someone already has and modify to what you wnat. You can always trade in corals and fish for store credit which you will always use. It sound to me like the equipment alone is worth what there are asking. IF its already cycled and has all the good critters in it your way ahead of the game.

Still waiting to hear from the guy but probably will still go custom unless it is awesome. I looked around 1 last time today to see on size and i think ill definitely go 180g 72x24x24, closed loop (2 or 3 returns?, what do you think?), 2 overflows offset or in corner, probably offset, like that look better unless there is some advantage to the corner overflows. Also, the 100g sump/fuge, So i think we can actually get to sizes and measurements whenever you get a chance

OK! I have to think about the CL :thinking: . I prefer the offset OF and returns in the corners.
Are you sure????????
I think i've heard that before! :hilarious

Yeah, im sure

The 30"h is just too high to work in and the 30"w makes it to hard to get a stand and would be a little too big for where im putting the tank.
The closed loop seems the easiest since i dont really want powerheads in the tank. The only question i still have is you said that its not really about flow but turnover. What about corals that need a med to high flow? are they gonna have to be in front of the cl returns or will the cl and overflow returns give the entire tank a fairly high flow?

No I said its not about PRESSURE, Its about FLOW and TURNOVER. If you have the right amount of turnover 15-20x the water has no choice but to move. as long as you don'y block the flow or create dead areas where the water can't flow then all will be well. I just don't like the single nozzle loc-line pumping out 200 gph to make sure the water can get around the tank. You will have at least 4-6 outlets and that should serve the purpose......
You're really sure!

Keep an open mind if you go look at it. Think about the cash and what it could be.
Have your self a vision.......
No worries either way!

I will but will probably go with the custom and most likely glasscages. They are BY FAR the cheapest and can do the stand and sump/fuge. Shipping is the only pain but they may be coming to south florida soon they said. I know they have some bad reviews but a ton of people have said they do good work so i guess ill trust that.
