my new 125g.. has 2 overflows.. im going to have 1" bulkhead and 1"PVC plumbed throughout it. im buying this sump and im buying a refugium from my LFS. they are made from the same company but there not connected so i gotta plumb it with gravity or something. but i heard that u dont want ur skimmer to skim the water that is from ur fuge. and i heard u dont want 100%flow to go to ur fuge.. how can i do this. but my main concern if i can connect it in like one circuit. my return pump would be the mag drive 1800gph? is that too much after all the hose its gotta go through and the splitting to return on both sides of the tank?

With two overflows and two 1" drain lines you'll have a good match with the Mag 18 return pump...
Tie the two drains together and then split and control flow to each the skimmer chamber (more) and Fuge (less)...
Are the overflows in the corners...?
If so i'd suggest a single OTT (over the top) return centered in the back rather than spliting return and losing flow...

yea there in both corners.... so if i have them meet then branch off into the sump and fuge.. ima need 2 return pumps because the sump is a different thingy all together..

One pump..fuge drains to return chamber..same as skimmer..
Wish we could post pics...saves typing a "thousand" words...:D

Wouldn't it be better to have the return chamber in the sump and have the fuge drain into there? With the high waterflow draining from the sump into a return chamber I would think you would have a bubble problem.

hey squid i change my mind... instead of spending 500 or so dollars on the sukmpand refuge im gonna make one. i have one picked out i wanna duplicate but before i do i want to kno its a awesome one for my 125. people said ur the best for thiskinda stuff.
http://www.melevsreef.com/acrylics/sumps/f/sump_f.html
awesome or no?
will it work with a euroreef cs6-2+ skimmer cause thats what ima buy for sure. let me know.... once i get the scoop if its a awesome setup ima start building it... heh

:yes: That's part of the "fine tuning" I was talking about...
The other is the drain line layout...

Mike...that's a pretty "decent" layout and definetly one worth persuing...
However :D , I don't care for the "teeth" in the fuge divider, you can "see" the turbulance it could (will) cause and "saltwater density" will NOT change that..:rolleyes:
The other area would be "re-calcing" the sizing on the chambers...
I think you could get a lot more "usable" Fuge room without sacrificing return chamber effeciency...

well **** i dont kno where to start to change it to only improve it. i dont kno what u want in a sump/refugium and dont want... what to change? id love to hear ur 2 sense..... because i was only gonna buy it off him cause i dont have all the tools to make the teeth and stuff. but if thats not good to have... ill umm buy the acrylic and make it here if i can..
what to change.... i wanna keep the 48" long 15" wide if i can....
and chamber sizees or baffles i have no clue what to do for those....
and i dunno what euroreef ima be using now since i kinda realize my tank is 125 and after sump and stuff it will be more so not sure what is a perfect skimmer for my setup..
but once i kno ima start the project heh

greaat no clue where to find that i see flow rate... for overflow lol
well im kinda reading.. lets start my building.. keep this link i want a sump built the same.. but with ur correct dimensions..
my stand 60x18x36.
i want a sump 48inches or so. thats big enough i think..
how about 16" wide?
hieght. i got a 36" stand so lets do
like a 20" high sump/refuge?
this give u a basic start for calculating with me everything
tank is 125gallon 60x18x24 Dual overflows. 1 in each corner
i didnt calculate the power off blackwash but 20" doesnt that leave enough room no matter?
this is gonna take weeks on this forum. isnt there AOL or something AIM names we can chat.. mine is mggray87
im just trying to get my sump/refuge made and my tank fullly plumbed within the next 2 weeks so forum would push that waiting for eachother replys heh

i change my mind on the dimensions
the whole sump/refuge will be 48"L x 15"W x 16"H
just like inthat link. but will u help me calculate the chamber sizes and baffle heights on both sides.. instead of the teeth thing like u said ima do baffles on the fuge also. so how do we start.... how do we get the 125g tank 60x18x24 with dual overflows backflow on power out i dont kno how u got that.
My Display Tank 60x18x24=25920/231=112.2 gallon (suppose to be 125 heh)
Sump/fuge tank 48x15x16=11520/231=49.8 gallon
backflow from main tank:
60x18x2"=2160/231=9.35 gallon backflow on power outtage.
Sump/fuge
48x15x4"=2880/231=12.46 gallon room so that will work.
3" will be exact the same as the backflow so i need to add the extra inch in case
so 35% of the tank is for fuge.. so 50gallon-12gallon=38gallon of water
38x.35=13.3gallon fuge so it will be 17"Lx15"Wx12"H for fuge chamber?correct?
Skimmer Chamber
euro-reef cs8-2 footprint 11"x13.5"
to make sure the skimmer fits so the water blowsout behind the skimmer to be an obstical for bubbles to go around to get to the return chamber so i gotta make the length of of the skimmer 14inches
am i right or wrong?
so My sump will be if i did it right
Skimmer Chamber= 14"Lx15"Wx12"H (or can it be higher i dunno?)
Refugium Chamber= 17"Lx15"Wx12"H
Return Chamber= 17"Lx15"Wx12"H
let me kno squid im trying! ahah
so ill have 3 baffles12" high the middle lifted about 1" or 1.5" and same on the refuge side.. so the middle one will be the one dividing the chambers perfectly. and 1" on both sides of the baffle put these?
thisis allgonnabe made with 1/4inch acrylic btw and the measurments of the whole sump is including the 1/4inch

You did good.. you found the formulas and have "most" of the math right...
Now lets "fine tune your numbers (if we can)...
backflow from main tank:
60x18x2"=2160/231=9.35 gallon backflow on power outtage.
>>>Good<<<
Sump/fuge
48x15x4"=2880/231=12.46 gallon room so that will work.
3" will be exact the same as the backflow so i need to add the extra inch in case..
>>> I usually figue backwash at 1 1/2" so figuring at 2" gives you plenty of "wiggle room"...But t doesn't have to be the "top" 3" of the S/F... Fuge can be full height and we'll make up the room in the skimmer/returmn chambers...<<<
so 35% of the tank is for fuge.. so 50gallon-12gallon=38gallon of water
38x.35=13.3gallon fuge so it will be 17"Lx15"Wx12"H for fuge chamber?correct?
>>>Depends... For an "Algal Scrubber" fuge where the main purpose of the fuge is to grow mass quantities of Macros for malnutrient removal through export...I reccomend 35% of "MAIN tank" as fuge or 40 gallons... But for other "purposes" other fuges can be sized differently... Look on page 1 or two of that thread for fuge "options".... and tell me what the main purpose of your fuge is...<<<
Skimmer Chamber
euro-reef cs8-2 footprint 11"x13.5"
to make sure the skimmer fits so the water blowsout behind the skimmer to be an obstical for bubbles to go around to get to the return chamber so i gotta make the length of of the skimmer 14inches
am i right or wrong?
>>> Bout right with room for "drain chamber" to catch water before it hits skimmer...<<<
so My sump will be if i did it right
Skimmer Chamber= 14"Lx15"Wx12"H (or can it be higher i dunno?)
>>>At 12" you will need a "shelf" to hold skimmer at proper opperating depth<<<
Refugium Chamber= 17"Lx15"Wx12"H
>>> Fuge chamber can be within 1" of top (14") but you may want to rethink the "taller" S?T to get the "volume" you want..<<
Return Chamber= 17"Lx15"Wx12"H
>>>Bout the right size (in combo with skimmer chamber) for your "proposed" flow...<<<
let me kno squid im trying! ahah
>>>Your getting there...<<<
so ill have 3 baffles12" high the middle lifted about 1" or 1.5" and same on the refuge side.. so the middle one will be the one dividing the chambers perfectly. and 1" on both sides of the baffle put these?
>>> 1 1/2" to 2" spacing 2" up<<<
>>> If you read through Leonas thread..you'll see she ended up with a 75 gallon tank to back up a 125 gallon tank...and WHY...<<<

the reason for my fuge is to keep my nitrates and other testings at 0. along with growing pods and stuff that will benifit the reef. and make an attempt to take all the algae outta the main tank so my tank is crystal clear ;)
and since we do 1.5" backflow we can move the space for the sump up 1 inch so it will be 3" off the top of the s/f. so
so my changes the skimmer size and height is fine.. ill just need a lil skimmer stand to lift it a lil bit.. which isnt a problem.
the refugium high will be 14" high.
what volume do i shoot for a s/f with my display tank.
then i can recalculate and u can recheck it. just give me that answer.. ;)
if i make the sump/refuge 48Lx15Wx20H
that will be about 62gallons total.
my main tank backwash 1.5x60x18=7.01 gallons.
Fuge chamber will be 18" high
62gallonsx.35=21.7gallons for fuge.
21.7x231=5012
Fuge dimensions 18.5Lx15Wx18H
Skimmer Chamber 14Lx15Wx12H
Return chamber would be 15.5Lx15Wx12H
so with the backwash it wont overflow if im correct correct? it would fill the return and skimmer section = to the refugium hieght first.. which is. 29.5Lx15Wx6H=11.5gallons so i have plenty of room for backwash... if im doing it right
so it should backwash up to about 2" from the top of the tank correct?
is this the volume i want? ima have trouble putting it in my stand im gonna have to build it in my stand i think hehe.
but is this better numbers... and if its all good.... now explain the baffle setup..

Numbers look good, but suggest you shorten return chamber to 10"X15"X12" and use the extra 5" for the fuge brining it to 23.5"X15x18 for 27.5 gallons (much more usable)
Backwash calcs still good for your tank..
Baffle layout as follows ...

ok.. so changed to:
Fuge dimensions 23.5Lx15Wx18H
Skimmer Chamber 14Lx15Wx12H
Return chamber would be 10.5Lx15Wx12H
but with the 1" baffle space i gotta push the fuge back 4 inches cause return is getting small and i cant touch the skimmer section cause it has atleast got to be 14". and this is roughly inches cause the acrylic is 1/4 inch so the baffles and stuff and walls but thats basically it? any changes?

With baffle "spacing" ...
Turn skimmer "sideways" and make the skimmer chamber 12" then fit a drain chamber in the available space (about 4"x4") with a 1" gap from bottom facing skimmer pump intake
Then a "set" of 1.5" baffles to return pump chamber
then a 9" return chambe with "secondary baffle set in 2" and 2" up (gives you 9" of "usable" volume and will handle the lower flow from the fuge...
Then a 24" fuge chamber..
