My Sump - DIY

[hfp75]

Well, I got a 20g long from Kijiji and took it apart, scraped the silicon off & put it all back together. Now, my silicone job was not a pretty as it could be but it will hold and it is a sump.

I then measured and had glass cut for the inside walls.

It is now siliconed together (Dap Blue 100% Silicone NO Anti-mold) & I'm waiting a day to make sure the Silicone is cured.

Dimensions are:
Tank - 30L x 14T x 12W

Chambers (R -> L) (the T (tall) height is the drop/fall to the next chamber. Include 12W for all below dimensions)

#1 - Live Rock (8.5W x 7.75T)
#2 - Skimmer (8.75W x 6.75T)
#3 - Walls to trap bubbles (3/4 apart from each other & 1/2 inch clearance at the bottem. I plan to put filter floss in between the baffles and not run a sock.)
#4 - Chaeto (3W x 5/8 clearance at the bottom)
#5 - Pump (RIO 2100)

I have a Phosban 150 with Rowaphos and a V2 Skim 400. I need some Chaeto (hint, hint if your in SW Calgary). I have a UV sterilizer to hook up also.

My debate is in chamber 1 under the live rock should I add a few inches of sand for a sand bed?

My tank above is a 55g with internal over flow - has 1-1.5" of 1-2mm sand (Fiji Pink) and a large amount of rock.

I also have an external canister filter and will run Carbon, Purigen and Matrix.

I am new to this so feedback is appreciated.

I hope for your sake that silicone holds up. I'm sure others have used it with success, but that stuff is ment to be a sealant. It does not have the same shear rating/strength as a proper silicone adhesive. There's a reason all custom tank shops use construction silicone adhesive like GE1200. For the interior baffles, no problem, as they don't really need the kind of strength the outer glass needs.

as long as you didn't take apart the outside walls you'll be fine.

I would put your refugium in chamber #5, Pump in #4, Filter sock in #1 and skimmer in #2. I also would have made the last piece of glass a lot taller so you could have more water volume in your refugium for a deeper sand bed and cheato and some live rock.

shoot me a pm and come on by. I have some Cheato you can have.

Agreed. If you just cut the old silicone from the corners, and left the structural silicone holding the glass together, and then just ran a new bead on the inside, you'll be fine. If you completely tore the tank down and re-assembled it (that's what I'm getting from the original post) then you're better off cutting it apart again, and using proper structural silicone.

Yes I totally disassembled and reassembled the sump and internal walls using the DAP silicone. The Sump is only 1/2'ish full of water. So far it has not had one problem.

I will be rebuilding it down the road. Not right away though as I'm still figuring this out. It will need a new layout for next time. I have read that some people have used that silicone to make way larger tanks with total success. I figured for a 10g sump it should work fine. If it matters I have left a fair amount of extra silicone around the edges inside the tank.

The seal on the inside doesn't really provide much structural support. All the strength is between the 2 pieces of glass. Like I said, odds are you'll be ok, but for peace of mind, next time use the construction adhesive. The internal baffles are fine with the dap stuff, but for the structural use the GE1200. There's another one that a lot of people use (can't recall the number), but I've always used the GE1200.

Heres an updated pic of my sump...

Works good, I'd modify it for next time but its doing what I want so I'm gonna leave it alone. Flow is not fast - I could open it up but it gets loud and I need time for the Chaeto, Reactor, Skimmer, ect to work... so slower than faster seems like a good way to go.

If I were doing it again, I'd make the wall on the right side (holding the Sand, rubble, and chaeto) higher, the baffolds - I'd space them better, over to floss 3" vs 1" and then under to Chemical filtration (purigen, carbon, ect) then over to the return pump......

I have 4+ inches of water over the return pump and it works fine - I do evap 1 +/- gallon a day. I can run 2+ days before I blow air if I dont top up the sump..... I have a Tunze ATO that I need to setup. Presto Problem solved - maybe next week.

Here is the updated chamber list:

Chambers (R -> L) (the T (tall) height is the drop/fall to the next chamber. Include 12W for all below dimensions)
* RED are my modifications

#1 - Live Rock/SAND/Chaeto (8.5W x 7.75T) (I'd make this a bit taller)
#2 - Skimmer/MATRIX (8.75W x 6.75T) (good height)
#3 - Walls to trap bubbles (Not effective - only waisted 2-3 inches here) (3/4 apart from each other & 1/2 inch clearance at the bottem (3/4+ clearance is better). I plan to put filter floss in between the baffles (impeded flow way to much, water just ran over it and not through it) and not run a sock.)
#4 - (NO) Chaeto - NOW Filter Floss folded in half & still no sock (3W x 5/8 clearance at the bottom)
#5 - Pump (RIO 2100) (pump is throttled back)

From #5 I have a 200gph pump that runs sump water to a Reactor (Rowaphos) and then to a UV sterilizer (9w TurboTwist) then back to chamber #2
I was contemplating a canister filter for the chemical filtration but am not gonna do that as the idea of a leak scares me. The Carbon and Purigen will be fit in somewhere.

looking good. by the way, if you didn't already know this, you can place pictures in-line with your post by using the image tags like this:

which will give you this result:

And if you don't want to type that all out there is a handy icon in the post editor that will do it for you. it's a little picture of a landscape/mountain with a square moon/sun.

Is the black pipe to the left of your gate valve your emergency over flow from the display tank to the sump? I would put ty raps on the little rubber elbows on your reactor as I've been told by J&L that they have been known to come off. Good safe guard against a flood.
