Need Help With Sump

[Redstratplayer1]

The sump is a 10 gallon it is 20inches long 10 inches wide 10 inches tall

The pump is a ViaAqua Water Pump it pumps 370gph and has a max head of 6ft.

The main tank is a 20 gallon and is 2ft above the bottom of the sump.

I need three glass baffles

Baffle one. 7 inches tall and 9 3/4 inches wide (to leave lots of room for silicone?)

Baffle two. 6 inches tall (This baffle will be between the two other baffals and raised one 1 inch above the bottom of the sump) and 9 3/4 inches wide(to leave lots of room for silicone?)

baffle three. 6 inches tall ? ( this baffle is on the pump side of the sump) and 9 3/4 inches wide(to leave lots of room for silicone?)

All three baffles will be made from 1/8 glass?



For the overflow box i will be using a glass corner calfo style overflow box (it needs to handle atleast 300 gph)

The main tank will be drilled about 3/4 the way up? The bulkhead will be 1inch ( I think that it can handle up to 600gph).

The over flow box will be made from 1/8 glass?

It will be
11 inches tall 5 inches long and 3 1/2 wide ?
So i need two pieces of glass.

Piece one . 11 x 5 inches

piece two. 11 x 3 1/2inches


Anything that has a ? after it means that i need some input.
Input on anything unmarked is also helpfull.

First off, have the bubble walls cut to 9 7/8" wide, you dont need a whole 1/4" for silicone

Have you seen my mantis nano redstrat? Great example of a small corner overflow there. Do NOT use glass for a corner overflow, use acrylic instead. Its a PITA to try and cut teeth into glass. If you have one, you can run the acrylic across a table saw to create the square teeth look the way I did. Also remember that the overflow needs to be wider than it is tall. Notice how short mine is from top to bottom.

i was thinking that it would be hard to use an acrilic with glass but i gues i will.

And yes ski i have seen your nano and i think i will go with that style overflow.


What size overflow should i go with It needs to handle 300gph ?

 

[Redstratplayer1]

I dont think i can get any weld on so maybe i will go with a glass flat overflow and use eggcrate to keep out fish.

Well remember, the internal overflow box can be created with silicone. It doesnt actually support any weight or load other than that of very lightweight acrylic. You're right to assume that silicone does not bond well to acrylic, but it does a good enough job for these purposes. I didn't use any weld-on on mine, just plain GE Silicone II, works like a charm. I'd aim for a 3/4" bulkhead just to be safe on the flowrate.

I have decided to use a Quiet one 1200 rated at 295gph.
After inputing all posible info into the RC Calculator .
The pump will put out 245gph at 2ft head .

The proper size drain is .65 inches but to be safe i am going with a 1inch bulkhead on a 1 3/4 inch hole.
Also the overflow needs to have atleast 4inches of area for water to flow over.So my over flow wil be 5 inches long to be safe.

in my experience, you dont need an internal overflow box if youre drilling the tank. i just run a 1.5" standpipe to the water line (in your case 1"), or if i drill the side of a tank, 90 up, and leave it open. ive never had a fish, snail, hermit, coral or ANYTHING take the plunge down to the sump. i just think it looks a lot more "clean" without the box in the display tank. but its understandable to worry so do what you feel is best for your tank!

Ahhhhhhhhhh................................

I want to have not to much flow in my sump only about 5x my tank volume.
But all of the recomended pumps are around 15x my tank.
The only pump that is the right sze is a Maxi jet 1200 that puts out 54gph at the right amount of head.

Can you use maxi jets as returns?

Sure, I use a dialed down maxi 1200 on my mantis nano. Its got some loose wiring though and cuts out from time to time, thats just cause its old though

 

[Redstratplayer1]

A maxi jet 1200 pumps 53gph at 2ft head.


Using the following input parameters
Gallons per Hour = 53

Drain and Overflow sizes are calculated as
Recommended minimum drain pipe diameter = 0.3 inches
Recommended minimum linear overflow size = 1 inches


They dont sell .3 inche bulkhead fitings so i am going with 1/2 inch on 1-1/8 hole.(edit just read an article on sumps, apparently the larger the hole the less sound so i will go with a 1 inch fitting on a 1 3/4 hole.)

The over flow will be.....(edit same as above the linear over flow size will be bigger)

4inches long (Edit 5 inches)
2 inches wide ( 3 )
2 inches deep (3 )

(I dont use 4x2x2 because i can never remember if it is lengthxhightxwidth or some other way)

I am going to go get my tank drilled and my glass cut as soon as get the answer to some Q's.

1. How far from the top lip should i get the glass drilled?

2.The two baffles that rest on the bottom of the tank are the same size right? And only the middle suspended baffle is a different height?

3. 1/8glass?

4.Any thing i am missing?

 

[SkiFletch]

1. So long as the hole is significantly lower than the top of the overflow box you're fin

2. correect

3. 1/8 is fine

4. a case of beer for when its done
