I need a tutorial.

The advantage of a dual-overflow is the amount of water you are able to move into your sump. From what I have read the max flow for a 1" PVC overflow (Similar to the one seen in the DIY Sticky) is somewhere in the neighborhood of 650 gph. By adding a second overflow you essentially double your gph flow capacity.

For example: Lets say you wanted to cycle your 220 tank 5 times an hour (which I realize is probably not enough to handle 12 large piranhas' bioload BUT...) Thats 1100 gallons per hour. So you find a Pump that can move 1100 gallons per hour at X ft of head height. A single 1" overflow could only empty 650 gph into your sump, so you would need a second, bringing your flow rate out of the aquarium up to 1300 gph.

DISCLAIMER: I have never built or used sump style Wet/Dry filtration utilizing overflows, and do not fully comprehend all of the logistics. This is simply how I understand the process. If I am wrong, please correct me, I will not be offended, and I plan on building a wet/dry sump filter in the future so by all means....

yes, of course what you wrote makes perfect sense. what do you think a good urnover rate would be for a tank of 20 caribas (I say 20 because my shoal is growing).

thanks
 
Today I bought a 100g glass tank to use as my sump. I think I know how to build the sump thanks to help from my buddy jb. I need 60g of bioballs, 2 overflows, a pump, et cetera.
 
please scratch the last post and read this one!

I have a 240 gallons tank.
I want a turnover rate of 6.5.
The top of my tank is 4.5 feet off the ground.
So i need a pump with a head at 4.5 that has a flow rate of 1560.

1. is this above pump assesment correct?

2. suppose i want to adjust the turnover after i buy the pump; may i do this by adjusting the valve on the tank inflow and tank outflow or will i do this by adjusting the pump, (if the pump has a power level option)? Do some pumps have power (output) options while others do not?

3. Are "supreme mag pumps" by Danner highly recomended? I think the 18 will be good for me.
 
what is a shim? do they put out a lot of heat? are they reliable for running long term, as in years? do yo know what the average working life is for a model 18? thanks.

I've been using Danner pumps in my systems for some time, they are a bit noisy, but if use shims so it does not touch the bottom of the sump they do a good job. For a model 18 you will get around 1200Gph. That would give you a 5 times per hours turn around rate.

I use a scrubbie under the pump just to move it off the bottom of my sump. Long running ... I've got a 250 running for the last 2 years & a 950 running on my 108G for the past 9 months without any problems. The only thing I keep on the ready is a new impeller since thats the only part that could really go wrong, cheap insurance ... As far as heat, since my pump is in the sump any heat that is made is use to heat the water.
You can look at my gallery to see my system !

what percentage of the area of your sump is scrubbies?
 
What I recommend doing is reading every post under the stickies in the top of the DIY and Filter sections. I know its a lot, but trust me its worth it. Click on my link in sig and you can see what I did for my 210gal...slightly different than most but I like a challenge. In my post I state that I would make a smaller DIY wet/dry for say like a 55gal use a 20gal or so. You can work out small kinks like section sizes, heights on sections, and best materials to work with. Reason I say this is once you start that big boy there is a LOT of water moving and it can make a big mess.

Hell, I was using my wet/dry SHOP VAC to suck start the 1 1/2 overflow I am using.

The info is very easy to find here and it will make sense as you work your way through it.

Good luck and give us a shout.

i will begin by making the overflows for my wet/dry.

theoretically speaking, i pretty much know what i am doing in building a sump and overflow. like you, i i enjoy more complicated or challenging projects. i think making a 100 gallon sump for my 240 is a great idea for many reasons, primarily, it will never overflow and i can expand my fish tank size and not be forced to expand my sump along with it.

my sump will cost a total of about $550.

sump supplies:

20 red manrove plants
100 gallon glass tank
egg crate
70 gallons of black bio balls
mechanical filter media
overflows
flexible vacuum tubing
acrylic lids
glass pieces
sillicone
acrylic pieces for suspending top and bottom egg crate shelves
mag 24
mag pre-filter
:nilly:
i have read quite a few of those stickies! thanks bro!
 
I've got about 1 cubic foot of scrubbies
