220g filtration plumbing?

[Pharaoh]

I like where your going with the loc line adapters, just make sure that you will have something setup to stop the water from backflowing when you turn off the system.

Have you thought about possibly running this on a closed loop system instead of a sump?

Does anyone know the actual flow rate of a 100 micron polypropylene and 100 micron polyester filter socks? I'm seeing 25gpm to 50gpm depending on what website I check. If so, that's 1,500-3,000gph per sock... so I shouldn't have any issues using them, especially if I split the two drain lines into 4 outputs emptying into 4 socks...

Are they suggesting 25 gpm (or 50 gpm) per square inch, per square foot, per entire sock?... the larger the area they are referencing the more flow it will allow...

Also bare in mind they are referencing the fllow with zero resistence, meaning zero crud collected in the sock. If your overflows are designed to be half way decent at collecting debris then you will need to clean the socks very frequently.

This is why I do not like the idea of just using socks as mechanical media... they clog up, resistence forms, the sock gets pushed off, everythign in the sock gets washed into your bio media... bio media becomes full of physical waste causing nitrates to increse unnecessarily fast... eventually you wash out the bio media in turn removing a portion of your bacteria...

But using a series of sponges or other mechanical media allows much more time between cleanings, is much less likely to result in large quantites of physical waste ever getting into the bio media, allows for much more thorough mechanical filtration...

I would drill it. A 220 with two 1" bulkheads is ridiculous IMO.

Why? you done need 12+ X turn over for a fresh water tank and anyone who tells you this is crazy. My tanks 100% clear with 5X turn over.

2 x 1" ID bulkheads offers an absoltue maximum of 1200 gph... If he meant 1" OD then it will be considerably less...

1200 gph on a 220 gal tank is not 12+ turnover...

1200+ gph on a 220 gal tank is not "crazy"...

I plan on installing a check valve on the return lines so that they can't back flush. I did think about going with a series of canister filters (like dawnmarie is), but just using two Ocean Clear Canisters would cost me around $300, plus I'd need 2 pumps.

And I like sumps.

As far as I could tell, the 25gpm and 50gpm were for the entire sock, clean.

I'm still waffling between the filter socks and poret foam (or both).

I have 12x turnover on both my 125g tanks, and if I had any less it wouldn't be enough (probably). I have heavily stocked tanks with large predatory fish, so yes, I DO NEED that much turnover.

And like NC_Nutcase says, 1,200gph isn't 12x turnover, its only 5.5x turnover on a 220g. The pump I'm getting is 3,000gph at 4' head, so that will be roughly 13.5x turnover, which is about where I want it to be.

Any chance I can reduce a 1.5" return line to 3x 3/4" lines? The issue is I'd like to use the lockline nozzle's from glass-holes.com, but the largest size is 3/4". If I were to run a single 1.5" return pipe up the back of he tank, then have 3x T's that are 1.5" on either end, and reduce to 3/4" on the T, then connect that 3/4" to 3/4" bulkheads, then to the lockline, is that going to be too restrictive for the flow? Or will 3x 3/4" return outlets be able to handle 3,000gph?

 

[Conner]

Here's a very crude paint drawing of what I mean...

 

[Conner]

Here's the overflow and return chamber for my 220g tank. The return chamber is sandwiched between two overflows, and is 2.75" wide by 5.5" front to back.

 

[Conner]

On a related note, do those overflows look like they can handle 3,000gph, or will I need to open up/remove those teeth to increase the amount of flow they can handle?

 

[Pharaoh]

The teeth look like they should be fine, but you'll never know until you fire up the system.

You should be fine with the 3x 3/4" lock-line. Have fun fitting those T's in there. I think that's the first overflow I've ever seen that was separated like that.
