that is it next time im in Winnipeg im coming over for a visit pm me your cell number and address buds i could have fun at your place drooling lol

This looks to be a VERY innovative way to build a drop-off tank!

I can't wait to see more pics!

ashr 01-26-2012 06:18 AM

very cool idea, cant wait to see it done!

Done.

Gripenfelter 01-30-2012 06:43 PM

Added 2 young black clowns, 2 azure damsels, and a GBTA along with 50 lbs of rock for the drop off.

Then added a 1350 GPH circulation pump to the area under the drop off to keep debris from building up there. I could have gone to 2000 GPH even.

More aquascaping and rock transfer this week.

Skimmerking 01-30-2012 06:45 PM

loving it man and that is it 1 pic Hmmmmmmmmmmmmmmmmmmmmm im not coming over now :mrgreen:

Gripenfelter 01-30-2012 06:48 PM

I'll post more tomorrow. Tank is a mess of rock right now. No aquascaping yet. Just moving rock all over.

Gripenfelter 01-31-2012 03:47 AM

Moved most of the coral over.

GSP will be at the bottom of the tank on the other side of the drop off.

Could you take a pic of the plumbing from you overflow for me please. I am planning a coast to coast in my 8' - 300 but I want it to be completely silent with no vertical pipes inside the tank.

Sure, I'll do that tonight.

I think a long tank would really benefit from it. I know in my setup the debris tends to circle around the return nozzles from the sump. It eventually finds it's way to the overflow but a coast to coast would work MUCH better.

lastlight 01-31-2012 04:01 PM

Nice to see some life in there! Will there be more rock added to the upper portion?

Speaking of overflows... I have a gyre in my tank and I can watch crap blast across the back, round the bend and make it's way across the front pane towards the overflow... only to turn that corner and drift within 3 inches of the overflow! Luckily things go around the tank all day so eventually it works out lol.

jjntm 01-31-2012 05:22 PM

this is a very cool Idea, out of curiousity tho, why not treat the baffles like a second sump/refugium? then live foods can venture into the tank at free will. also can be a sweet breeder area of the tank for inverts and smaller fish. personally I think you have a sweet lil Idea there, I'm gonna follow this thread, as I am curious to see if the 350gph will be enough flow... after all you don't need a hell of a lot of flow for a refug...

There will be a little more rock in the upper portion but just to mount coral to. I went a bit overboard in my 120 gallon and had 200 lbs of rock...too much. Not doing that this time. Most of my rock will be in the sump and refugium with just enough in the display tank to look cool.

No light will penetrate the baffles once there is sand on the top so nothing will grow there. I was thinking of making it a refugium at first too but it's not a viable option. I could have filled it with live rock to make it a refuge for copepods but I already have a ridiculous amount of them living in my sump and filters.

lastlight 01-31-2012 07:01 PM

No reason you can't have a light shooting into there from the side under the overflow =)

I doubt it would penetrate all the baffles. There is a good amount of grime and dust already on the glass.

And you don't think that'll cause nitrate problems in the tank?

Not with a 1350 GPH pump circulating water in there.

I tried it without the pump and within 2 weeks I had a layer of crap in there so thick you couldn't see the glass.

After 2 days of using the pump 99% of the grime is gone.

TimT 01-31-2012 07:22 PM

Hi Grip,

Looks great and love the idea.

Only one small concern.
The submersible pump under the shelf will be a nightmare to service. I would either move it above the lid or use a Korallia blowing down into the first chamber next to the overflows.

My recommendation would be to put some fist sized chunks of live rock in the chambers. Have a Korallia or two blowing water down into the first chamber next to overflows. Put some egg crate on the holes in the last chamber to stop snails, crabs and fish from getting in. That area is a great place to have the bio filtration happening. As an added bonus you could have the korallia's on a computer UPS so that in case of a power failure you don't lose the tank. A computer UPS will run a Korallia for a long time.

Cheers,
Tim

Thanks Tim. I'll look into moving the pump above the shelf and hiding it with rock. Thanks again for all your help with the plumbing supplies.

Gripenfelter 02-01-2012 02:27 PM

Even though it's 314 gallons I'm a little scared to add my false perc clowns to it with my black clowns in there. My black clowns are still young and do not host anemones. They just do laps of the entire tank. Hopefully the mirror trick will work otherwise I'll have to fish 2 of them out.
Anyways here are some more pics. Still need to add about 75 lbs more rock for aquascaping and get some more cool rock from Fish Whisperer.
Anyways, turned the lights 90 degrees around for the corals. They are too close to the surface so I don't get a nice spread of light. The lights over the deep end will be length wise.

Cool thanks for the more detailed pics of the OF, that is exactly what I thought it was :biggrin: and helps with my design greatly.

Skimmerking 02-01-2012 03:05 PM

I would add the clowns right away just to get them in there serious thou since they have young and wont be bothered so much

Here is an exploded pic:

This is the secondary siphon.


The primary siphon is identical to the secondary except that it doesn't have the tube fitting on the top. The emergency siphon is identical to the primary siphon except that it has it's elbow turned upwards.

I didn't draw those particular ones but I always use Google Sketchup for 3D renderings. It's free and there are lots of video tutorials on how to use it.

hmm, is there an extension to have these plumbing parts??

OIC.

Yeah you can download the individual parts from the Google Sketchup library and modify to your own.

I wonder how I can make this work on an 8' long overflow?

What would be the problem? I connected 3 tanks together...150 gallons. All three pipes dump into my refugium.

The Grizz 02-01-2012 07:00 PM

My question would be where to locate the drains, how many drains. Would I do 4 main and 2 emergency or just 2 & 1?

Gripenfelter 02-01-2012 07:04 PM

You only need 3.

At 5700 GPH my main siphon is 95% open. If I made it 100% open it would suck the overflow dry.

The way you set it is to set the main siphon so it is slightly slower than the flow of water entering the overflow.

Then you set the secondary open so it will suck up just enough to keep the water level from rising. If the water level rises to the point where it reaches the airline, the secondary also goes full siphon.

If for some reason the first two are clogged the emergency, which is never used, will go full siphon.

So really there are 2 fail safes. Anymore drains than this are overkill.

The Grizz 02-01-2012 07:13 PM

OH OK, that makes sense now and great explanation of how it works. What I had originally thought of doing was to put a drain at each end of the coast to coast and have the c -c split in half, 4' feeding each overflow but doing this i could just put it in the middle of the tank with maybe 1' between each hole.

I really like how this look and it sounds like it works well to. I want to be able to feed my skimmer, reactors and if needed my chiller off my overflows so they get as much of the yukie goodness they can.

You'd want all the drains going to one place. Or at least your main one. The other 2 will have a minimal amount of water going through them.

Doesn't matter where in the coast to coast overflow you put the drains. I would space them out as much as possible but you can also put them right beside one another.

The Grizz 02-01-2012 10:13 PM

All the drains will be going to one place, thinking of putting in a short 3" piece of pipe at the end of all the drains to collect in and then take off for my skimmer & reactors.

Thanks so much for the info!! What kind of flex pipe did you use? Was it fairly easy to work with?

I am really digging the drop off you have going :thumb:

I would recommend not connecting all the drains together. The point of this fail safe system is that if one pipe gets clogged you still have 2 back ups. If you connect them all together and they clog at the point where you connected all of them together you will have a swimming pool in your house.

Gripenfelter 02-02-2012 01:46 PM

Moved over 75% of the rock from the other tank. Did some aquascaping. My apartment complex (caves on the drop off) for the fishes is starting to take shape.
http://i329.photobucket.com/albums/l...h/0cc6ecb9.jpg
Half of a tower/bridge I'm building.

Looking length-wise into the tank.


http://i329.photobucket.com/albums/l...h/891a7711.jpg
The apartment complex.


http://i329.photobucket.com/albums/l...h/c0e034d6.jpg
Slowly getting there.

Still need a lot more rock for the drop off. I'll be transferring more over today and hopefully some fish today or tomorrow and finish aquascaping this weekend.

Then add sand.

The side panels should arrive in 2 weeks. Went with black aluminum. A buddy of mine races circle track and uses black aluminum for the body panels on their race car so he's going to snag me some pieces.
