Frag System is too loud

[DwightKeenan]

So I filled the tanks with water and started mixing salt in them. I left the caps off of the T on the top of the durso standpipes and of course they are sucking in too much air and loud.

When I drill a tiny hole in the cap, the tanks are still too loud and the water level fluctuates. I did a durso on my 75 and had no issues, but for some reason this setup is sucking in air and sounds like a toilet.

Any ideas?

Did you do the weird elbow I suggested inthe sump? Or better yet where the does the sound seem like it is coming from?

When I had a sump with a modified durso, i drilled a few different sized holes in the cap. Then, I used tape to seal off different combinations and it helped a bit.

If you can take some detailed pictures of your plumbing and where the noise is coming from, it'd really help us all figure things out. Remember that there's just no such thing as silent tank plumbing when you're dealing with a Durso (unless you use a ball/gate valve on the drain line, which introduces a flood hazard). Also, the more flow you put through a durso, the more noise you have to put up with as well.

But, that said, a Durso can be pretty quiet once you get the kinds out of it. Also, it takes a few weeks to get a good slime coating on the plumbing. My Durso was really noise during the rebuild until I just let it "be" for a few weeks; after those few weeks of obnoxious noise, it's about 90% better just because of the break-in and slime coat.

Right now the noise is coming from the two spots with teh red arrows. They are loc line connectors and every few seconds they are loud and tons of bubbles come out.

Cary, I did put the double 90 where the water enters the sump to divert bubbles up, but that doesn't seem to be the issue. It is where the top tank feeds the 2nd and the 2nd feeds the third. I guess it doesn't have to be silent, but that is way more than my 75 ever made, plus it shoots air bubbles into the tanks.

ok can you drill a hole at the top of plumbed lines? next tank up from the arrows

[schneijt]

Since Dursos need to pull in air to prevent a siphon, unfortunately you're going to see the air in the tanks that the Durso's are draining into... If you cut down on the flow through the system, it should help to minimize the noise. Also, giving it time to "break-in" will help out. Are you going to put a powerhead in each tank to give some random flow to the corals? If you're counting on the return pump and your plumbing to do all the flow inside the tanks for you, it's going to have the unfortunate side effect of moving more water through the Dursos and causing more possible noise.

Every time I've tried to plumb anything like you've set up, I end up dialing down the flow until I find an acceptable level of air/noise. Sorry I don't have a magic solution for you other than to let it break it and try to reduce the flow a little bit if you can.

I have caps on the top of each durso stand pipe and have drilled a tiny hole that was so small it kind of stopped the flow, then I made it the next drill bit size up and it still has the noise.

[DwightKeenan]

I am going to let it break in for a few weeks to see if that helps. Then I am going to put a tee on the return line so I can divert some of the flow bank into the sump and play with reducing the flow too.

I plan to have powerheads in each tank so I am not expecting to use the return pump for flow in each tank.

Time will tell if my plan works.


I am also going to pull out the pink foam and actually put a board under each tank that completely distributes the weight across the entire shelf. There is a sligh bowing from the weight and I am just too nervous about it.

Good call on the board... I was worried that it might be an issue as the stand just looked like a wire stand... If you do put boards make sure the boards are full length of the stand so that the edges of the boards are touching the outside bracing thus better distributing the weight. HTH

I had this problem once and I used a sponge filter in the pvc so the air would be muffled and it worked for me I dont know if it was luck or not but it don't hurt to try.
good luck

So I bought boards today to put under the tanks to help distribute the weight better. The issue now is that the boards are 4 feet long, which is perfect, but they are only 15 1/2 inches wide and the shelf is 18 wide in the center. I placed the top tank on a shelf and it is perfectly level, however becuase of the way the shelf is built by having hte wood on the end pieces the wood bows a hair because the end pieces are about 1/8" higher than the innner part of the shelf. Should I cut the ends off the shelf so it doesn't rest on the end pieces that way it is flat every where or not worry about it at all?

I would make it flat. Bows not good.

[DwightKeenan]

Yeah, that is what I thought.

Crap, crap, crap!!!

It is hard to build all of this stuff while on crutches!

I really need to get some help with my addiction!!!
