I'm gonna C&P this so I don't have to re write it (again 
) and then "re-do" with the new numbers...
Probably should do some "math"...first...huh...? :jumping:
Backwash room first...then the fuge..then the skimmer chamber..then the return chamber...then the overflow driain chamber...
55Gallon soon to be S/F is 48"x13"x20"=12480/231=54.04
>>>75 gallon S/F is 48x18x20=17280/231=74.8 gallons<<<
We can't "use" all that, because you want to leave some room for "backwash" in a power out situation...so lets see 3"-4" will leave us..
4"x48x13=2496/231=10 gallons for "backwash" room...
>>>4x48x18=3456/231=14.96 (15 gallons)Backwash<<<
Everybody OK with that...?? (hint: check back on page 4)
>>>We may "use" some of that for TSV (total system volume)<<<
So that leaves us 44-45 gallons to "play" with...
>>>60 gallons...now we're gettin somewhere...<<<
I'm going to talk in "percentages" here...
First to explain what's "Ideal" and why...for those that are following along and may have a different sized tank...
Then we'll size it in to "reality" (what we have to work with) because not everybody can put the "Ultimate" S/F in their basement to get the room they need...although the more ambitious of you out there might...
I generally "recomend" 50% of Main Tank volume for Fuge on tanks under 100 gallons...Then 30-35% up to 180 gallon MTs...and then 25% for larger...
>>>120x.3=36 and 120x.35=42 ... So we're looking for 40 gallons...this we can do and still have 20 for the overflow drain and return...looks good so far...<<<
Obviously we cant use the full 45 gallons for the Fuge and have any thing for the sump, so we'll have to compromise a "little" ...
Leona is "close to" the 100 gallon mark so let's see what the 30-35% MT gives us...
90x.3=27 and 90x.35=31.5 So we're looking for "around" 30 gallons for the Fuge...
>>>120x.3=36 and 120x.35=42 ... So we're looking for 40 gallons...this we can do and still have 20 for the overflow drain and return...looks good so far...<<<
So..Tonight's Math quiz is...
How big will a 40 gallon fuge be in Leonas 75 gallon tank if we leave 4" backwash room in it ...??
AND How much "room" does that leave for Skimmer footprint and return pump area...??
Don't forget we need to add "baffles" as well...:thinking:
Leona...we'll need the footprint of your skimmer for the "next" step...was that going to be a Euro Reef ES5-3..??
>>> Now we know it's 11"X13"....ASM G-2 <<<
So we still have a "Math Quiz" (you didn't think I'd let you off that easy did you)...
What will the "foot print" of a 40 gallon fuge be in the 75 ...??
And what kind of room does that leave for the O/F Drain, Skimmer and Return chambers...?? :thinking:

Yep...that's about it...:yes:
Now we start laying it out on paper (or "paint") and see what that's going to look like...
We want to "pencil in" the skimmer and return pump as close to "scale" as we can get to see that everything "fits" and makes scense...
And we may have to "adjust it" a time or two to fit the baffles and O/F drain chamber in...but it's a lot easier to "Cut and Paste" in Paint then it is to glue them in and find out the skimmer won't fit...
First shot with the "numbers" ....32" for Fuge and at least 11 for Skimmer footprint..only leaves 5" for return chamber and we haven't added baffles yet...
We will need to "squeeze the fuge down 2"-3" at least (to fit pump and baffles) but we can make up a bit of the fuge size by making it "taller"....
We had twice as much "backwash" room as we needed...and we"ll gain more in the skimmer and return pump chamber, because they will "run" at a lower level to begin with...
We also want to concider "lighting" the fuge...Probably something in the 24" PC or VHO range...:thinking: (we"ll get "deeper" into this later)...
So we could go as short as 28"X18x18 = 39.7 and still get our 40 gallon "Goal"...:joy:
But make note...we will need to "reconcider/re-measure" for backwash room as we progress...
First pic...

We have to hold up on the sump/fuge just for a few posts. I need the layout for the tank.
Is everything the same?
1 left end panel hole 1 3/4"
1 right end panel hole 1 3/4"
1 Left Back hole 1 3/4"
1 Middle back hole 2 3/8"
1 Right back hole 1 3/4"
2 Standard size Corner Overflows 1 on each corner
Euro Bracing
NO center bracing? I've heard that you have to tell him this. That's what I want correct. That's the glass that he will put in the middle across the tank.
Is that it? Is that correct. I think I will also order the bulkheads through him and I will need 5 correct?
Do I need to map this out to him or If I explained it to him it would be good enough. If I have to map it out I might need help. Does it matter if the middle holes are in a straight line or triangle or spaced out.
The holes in the corner will he know exactly were to put them or do I need to tell him this. I'm assuming I need to take into consideration about my sand bed also when figuring out were the holes go. Also we will be adding steel bars under our home to support the weight of the tank.
Squidd when this is said and done you will have to send me your addy snail mail so I can send you a thank you gift.
Thanks All.

OK Fine... Let's just jump around all over the place...
You know what they say about "left brained" people don't you...??
They're not in their "right mind"...
J/K...It's all Good....and you probably should order up the tank "ahead" of time to get it in time...
You can start a "search" if you want...and give me some time to dig up some "pics"...
And then we can do a quick "layout", discuss some options for flow, and we'll "draw up" a layout you can print or e-mail Tom...
But now it's time for me to go to bed...Mondays are "early" for me...:sleepy:

Squidd,
What's is the idea of the 1 1/4" return lines on the Mag 12? Aren't the intake and outputs 3/4 id? Seems like a big time overkill to me but I'm no engineer. Can you explain?
The 3/4" is just what they "leave" you to hook up to...it's part of "their' design to chamber the pump and impeller...
If it just "squirted" out from there (0 feet "head") you'd be fine... at 1200 gph...
BUT...we need to push it up hill to the tank (4' head) and through a couple elbows...and every "tight" inch adds restriction, and a lowering of flow...
In order to maintain a "reasonable" amount (or "control" the amount) of flow we need to give it some "breathing" room...
As the line gets bigger...the more "flow" can go through...(within reason)...
So a Mag 12 - 4' head with 3-90* elbows will "deliver" ...
761 gph with 3/4" line...
942 gph with 1" line...
1037 gph with 1 1/4" line...and
1061 gph with 1 1/2" line...
You can see there's not much gain going to 1 1/2" line but there is a gain in flow from 3/4" to 1" and 1" to 1 1/4"...
That's just for this pump... and other makes and models will be more effective at other varining sized lines...
