Dan's 150 Rebuild

[Sobo's Reef]

Well the tank is fully operational. Just have to quiet it down some and I'll be set. Hopefully all my coral and fish make it. But I think I put in a good 12hrs today so I am going to beddddd... So exhausted

Drill a hole just big enough for a piece if airline in the 90 on top of the standpipe and put a piece of airline in until it stops dumping. Or cut the stand pipe down and build a durso with a T a cap with a small hole drilled and a street 90. Like this:


Either way should fix the issue

 

[kschweer]

Also you can get new 90's for your returns without the hole for a siphon break. Just keep your return nozzles just under the surface of the water

 

[Sobo's Reef]

These pipes already have the hole drilled in em with airline coming out Lol

congrats on getting the new tank up man

 

[Sobo's Reef]

Thank you! Now I just gotta make it shut up! Lol

 

[Sobo's Reef]

Yeah I didn't think about just replacing the 90's on the returns Lol I think I have em but not sure if I have threaded ones for the locline. That'll quiet it down a lot. But the whole dumping thing really needs to stop. It sounded a lil better this morning, but then again I could have just gotten used to it already Lol when I get home later tonight I'll post a pic of the standpipe so you guys can see what I'm talking about

I thought you were setting up a Herbie?

Anyway, the siphon action going on with right side is likely from the little hole in the top being clogged of the height of the durso not set right. Check the hole, and if that is not it, raise or lower the durso to adjust the siphon action.


EDIT TO ADD: Just saw your other set of pictures above....that in not a durso??? I'm lost....I don't know what you have.

Yeah they're not dursos, its whatever product comes with a Marineland RR package.

You may have to dial down the pump a bit. I use the megaflow from aqueon. Very good IMO and pretty quiet unless you try to push too much water.

 

[Sobo's Reef]

How can I do that now that all my plumbing is in place tho?

Are your drains flushing? How do your drain lines dump into your sump? Are they above or below the waterline in your sump? I'm guessing that they are below and that the lines aren't letting the air vent which is causing them to fill up until a siphon starts. The siphon drains the lines until they hit that siphon break and the cycle starts all over again.

Not sure what you mean by flushing but the left drain drains straight down into the sump about 4-5" below water level, this one is okay. The right side is coming down into a 45 then into another 45(reversed) and angled a lil bit about 4-5" under the water level.

I originally had it set up just with 1 45 and an angle but it was right up against the baffle. Thought maybe that was the reason why, so I took it off, put another 45 on and reversed the pipe towards the other end of the tank and still have the same result

EDIT: the pics I posted a few posts back show how the water level is moving near the siphon break. What you said about the cycle starting again sounds about right but how the hell do I fix that? Lol

I concur. Drill a few small holes in PVC where it enters the sump right above the water line. I did a series of 1/8" holes and this will help. Also the air line coming out of the to is there to push up or down. This will also help to quiet it down. Lastly as I said before you can do all this and it will still be loud and still flush if you try to push to much water through. While they are capable of handeling 700GPH they won't do it quietly. Did you install ball valve on the return lines? If not then try to use one of the other lines off off the manifold to cut down on some of the flow going to the DT.


By "flushing we mean the water going up and down in the overflow chamber.

Start by adding some holes in the pvc where you said it goes about 4-5" below the surface. Better yet if you can remove those pieces cut some slits in them ending about 1/2" above the surface of the water.

He has a manifold.....just take one of the manifold lines, put a short hose on it, and run it back into the sump. Adjust the valve to reduce the flow to the DT.

Alright I'll see what I can do when I get home tonight, unfortunately I won't be home til 730 tonight.

John - I did not install a ball valve(always thought you shouldn't restrict the return pump flow?) I barely have any PVC for the returns, its mostly all flex PVC other than the actually pieces coming out of the bulkheads and the manifold.

Paul - will opening up a valve on my manifold really help with the amount of water coming down the drain? Wouldn't it just reduce the flow going into the tank?

 

[jgraz]

Yes it will cut down in flow to the tank. Which is what I said as well. IMO you have too much flow going to the DT. You can restrict the pump though it is not the best thing to do which is why I suggested running a line off the manifold to the sump. That will pull off some flow to the DT. That said you still should add some holes to the overflow lines right above the water line in the sump.

 

[Sobo's Reef]

Alright I'll definitely do that then, I'll let you guys know how it goes later on tonight! Thanks for being patient with me!! I'm just glad all my plumbing is leak free doesn't look the best but it works lol

I have one T off of my return so no fancy manifold thing it goes to TLF reactor and back into the sump, the Mag 12 was just too much flow so either it flushed or you got the waterfall sound. The less water you have pumped into the DT the less water through the overflows basically.
Manifold should help same way.

 

[Sobo's Reef]

Yeah I'm hoping so! I have a mag 18 and to be honest, I didn't think it was going to be this much flow considering on my last tank I had it going thru 3 separate loclines on the return, I guess I just assumed it would have the same amount of flow but I was wrong lol

 

[Sobo's Reef]

Just got home. Stopped at Lowes to pick up a few 90's for the returns. The tank is a lot more quiet as far as dumping into the sump. Any reasoning behind this? Maybe it just had the break in?

I'm still gonna either open the valve and/or cut slits into the drain and see where that leaves me
