Worm's 180 build

[worm5406]

OK Quick question for those following.

I am positioned to get a friends 265. It is not drilled.

He is using OTB for drains and feed.

I was thinking of drilling the back and making it a C2C overflow. Feed... Humm IDK yet. Looking for ideas.

Ready to pull the trigger.

Man 265? Are the dimensions 84″ x 24″ x 30″? If so I like it! That a whole lot of swim area. Also I would love to see a new "worm build"

This is big news, I say go for it but I doubt anyone will say otherwise.. Lol

Me too. LOL...

It would probably be called worm 640.

I have a 180DT+120DT+75sump so add 265... oops and two 75g sumps. Now it is 790.

Hummm... What am I getting my self into? I might just leave the 120/180 separate from the 265.

Yeah I know, still thinking though. Hair trigger though.

You know the owner.

Oh thanks.. so much for a conscience.

Oh thanks.. so much for a conscience.

Oh I thought you would combine a few into it.

I think that's when science is used to con someone. :hmm5:

Sounds like Republican logic.

Conscience is an aptitude, faculty, intuition or judgment that assists in distinguishing right from wrong. Moral judgment may derive from values or norms (principles and rules). In psychological terms conscience is often described as leading to feelings of remorse when a human commits actions that go against his/her moral values and to feelings of rectitude or integrity when actions conform to such norms. The extent to which conscience informs moral judgment before an action and whether such moral judgments are or should be based in reason has occasioned debate through much of the history of Western philosophy.

Love your bristleworm gif, btw. That should ease the fears of those who think these must be eradicated from reef tanks.

[worm5406]

I keep trying. As long as you keep them in line they are good. LOL

Thanks!

 

[worm5406]

Well I took the safety off.

Finger is on the trigger.

If I pull it I will have to do a LOT of work to get it ready for the 265.

Drilling the back wall of the tank too for a C2C overflow.

I was thinking on the C2C to make it tooth less.

Ideas?


Uuugh... New thread may called:

370g TV upgrade to 777g TV

IDK... Ideas for that too... LOL

 

[iced98lx]

LOL Go for it. Drill the back, do CTC.

OR

Take the opportunity and take it to a glass shop, have a slot ground, external CTC...

You know, in case you didn't have enough thoughts.

 

[dave.m]

I thought we had had it out on c2c toothed vs non-toothed on pmrogers' thread.

[worm5406]

Yeah... but.... well... let me go ready again.

I was thinking of... well let me just go read.

 

[worm5406]

Well that is horrible.. Typed a long response. Lost connection... did a back.. and it was all gone... UUGH.


Let me paraphrase.


OK... I re-read all of the thread and the lifting pictures plus some. LOL

I agree the weirs raise the water level slightly to allow detritus to flow out of the tank. A non-weir has a slimmer profile water height. That being typed. Agitated water surface (not roman rapids) will allow for varying water height across the lip also.

OK though.. I will get a weir, but I am going to see if it can be removable for cleaning, and get a spare, in-case I break it. I am afraid that is going to be more trouble than it will be worth, the removable one. It will probably be just a standard weir. I do like toothless though, He is a Night Fury, btw.

I'm confused by your terminology. A weir is a straight fence with no notches/teeth. That is what it is referred to as in terms of flow dynamics. One of our mechanical engineers has a Flow Dynamics book and that's where I got my equation for calculating the necessary dimensions for a true C2C weir for a given flow rate and water height over the weir.

A notched weir is different, same calc but you have to throw in a constant to take care of the flow restriction created by passing the water through notches. Essentially you add up the width of all the notches and then multiply by 0.55. So if you have a notched overflow with 1/4" notches every 1/2" (so 1/4" teeth, 1/4" notch, etc) and that overflow is 48" long, that's 24" of total width but only 13" effective.

So if you have, say, 1/2" of water above the bottom of the notch in the 48" notched overflow, you would get the same flow rate across a weir that is only 13" wide.

If you make a really long weir, you can push a ton of water across it via a very thin profile (small water height over the top of the weir)

I think most people forget this and think if I have 1" of water on my notched box it's going to be maybe 1/2 that on a flat weir, because I'm just removing the notches. It's more like 4x less.

 

[worm5406]

I meant tooth vs toothless or notched vs notchless or comb vs combless.

84 inches long sound a bit better? (no she said jokes here)

Beananimal drain out the back.


Without having to go look, what is the height of a normal overflow (top to bottom) and what is the depth (back of tank to edge). Just curious. In a meeting at work on cell. Harder to switch and not seem obvious. LOL Hope things are spelled correctly.
