Sounds good. Sometimes my paranoia gets in the way of sound mechanics and physics.

No,just the silicon.I am not at all worried about it falling.The overflow when in use,still has quite a bit of air above the water level in the overflow.In theory,this should provide a little buoyancy thus creating an upward force from the water below it.Probably just a crazy theory of mine.Being that tanks are constructed of silicon,and have tremendous pressure near the bottom.The amount of pressure exerted on the overflow up near the top shouldn't be that much.

Dave -

Do you have anything besides silicone fixing the overflow to the back wall? Are you worried about the glass being too heavy for the silicone to hold long-term?

Thanks!

ah, fab pics Dave. Much thanks for sharing... I'm going to post a thread with these links for the benefit of folks looking to search for/chat about this (off)topic specifically.

Here's the horizontal overflow i built for my 75gal i just setup.I just used 3 pieces of glass siliconed to the back.After useing one for the first time,I can now confirm that these are the quietest/best overflows i've ever used.

Kelly, Thanks for the response. We live in the same city and have to communicate VIA a national forum. Oh well. Ordered the tank today from glass cages. 4 - 1" drains, 2 - 1" returns, 2" CL feed. They are going to build and install the horozintal overflow across the back and eurobrace the tank. Talked to Todd today about a sump/fuge and skimmer. He had some good suggestions. Should be able to have it up and running by the meeting in may. Also i have replaced the 72 bow in the livingroom with a 120 - basement sump setup.

Victor,

Glad you joined MarineDepot.com!

I am pretty sure I know what Anthony would recommend about the overflow box - 3 sides. You can build one yourself. Terry S built mine. Ican post some pics if you want.

Use a manifold and you can useball valves to adjust the flow to the tank, fuge, skimmer, etc

Can't wait to see your new system at an upcoming LMAS meeting at your place.

I think I am going with a 50gl (36 x 18 x 17) for a little extra hight. Ordering from glass cages. Will talk to them about 4 holes in the overflow, which woll make 6 across the top back wall with the 2 returns. If that is to many holes, wouldnt it be OK to go with 3 and use 900ghp pump. BTW Anthony, they say that they will not install a horzontal overflow, no support, won't hold. I can get one built local. Do you reccomend 4 sides with holes to match the tank holes, or 3 sides siliconed to the tank. Now to the sump fuge setup. Will have it custom built locally. 3 compartment, skimmer, fuge, return. Confused about gentle flow through the sump loop and strong flow through the fuge to get the ball rooling. Possibly use a larger than needed return pump and t off a return line into the fuge section for added circulation. Thoughts.

See, I don't have a bubble problem at all. I have a 120 gallon display with a 50 breeder sump/refugium with two Mag-Drive 1200's as return pumps and no bubbles make it out of the first chamber.

I will have to take and post a picture sometime.

RE: 40 breeder project

davejnz — Thu, 16 Feb 2006 00:26:36 GMT

Personally,I think 1200gph is too much flow through your sump.I also have a 40breeder,I use a 30gal(36"L)tank for a sump.My return pump is a MAG 12 and i estimated after head loss,I'm around 900gph.In hindsight,I would of went with a smaller pump.My sump has 2 sets(3 each)of baffles dividing the return chamber from the skimmer chamber.I still have a microbubble problem.

RE: 40 breeder project

Anthony Calfo — Wed, 15 Feb 2006 21:32:39 GMT

yep... agreed... two 1" drains for 1200 gph is scary. Just scary.

RE: 40 breeder project

Steven Pro — Wed, 15 Feb 2006 16:31:32 GMT

Yes, I would use four 1" bulkheads for drains. Each 1" bulkhead mounted horizontally is capable of quietly handling 300-400 gph. Beyond that they start a siphon. Imagine the noise of a toilet bowl flushing 24/7. And then after about a day or two of that, imagine your significant other beating you senseless in your sleep because they can't get any rest from the racket.

A pressure rated pump is fine.

VicMiller — Wed, 15 Feb 2006 15:52:50 GMT

Thanks for the advice guys. Steve, you are reccomending 4 - 1" drains in the overflow? Im thinking 2 - 1" drains should support 1200 gph, isnt that enough flow through the sump with a CLM with up to 2000 gph. On the pumps needing aprox 2000 gph are there any reccomendations. Would a dart at 3600 gph(throtled back to 2M be overkill) Iwaki md100rlt is pressure pump (not correct for circulation application?)

Anthony Calfo — Wed, 15 Feb 2006 09:12:23 GMT

thanks Steve!

Cheers Vic -

I agree... the two feed lines are less desirable than one large intake (2")... I also very much agree with the choice of a japanses Iwaki (time tested long term performance and value)

I'd also step the CLM plumbing up to at least 1.5" here (though you can still reduce to 3/4" at the tees... but use 1"X3/4" reducers for the option to use a larger pump in the future).

As for the use of flaring ends... not likely needed. Use them only afterwards if/as needed to tweak specific problem spots or to reduce tees with excess flow shares.

I inserted my recommended changes in bold type.

These questions were partially asked at another thread but decided to start my own. Want to do this one right, smaller tanks less room for error. 3 X 4 X 16 horizontal overflow, 4 1" drains, Iwaki MD40rlxt return, (excess flow will bleed off from a T back to the sump instead of restricting the output). 1" bulkheads in rear corners for returns each with t's for 4 outlets. CLM, 3 outlets across the front 1 on each end. 5x300to400, need 1500 to 2000 gph pump, possibly ampmaster 2100. Feed the pump with 2 1" bulkheads, from rear center of tank.

Questions, 1/ CLM feed 2 1" or 1 2" which is better? - Probably doesn't matter much except that the plumbing might be easier with one hole, but you also need access to two holes saws too.

2/ CLM pipe and outlets, 1" pipe with 3/4 outlets to flairs? - Sounds fine to me.

3/ Pumps, are these good choices or do you have other recomendations. Will have more questions about sump and fuge configuration as project progresses. - I really like the Japanese made Iwaki's, but have no experience with the Ampmasters.
