I am glad you got it tuned in (not much trouble at all was it!)

The tank is in the living room right next to the TV, and before you always had to turn up the TV a little extra to drown out the noise of the 55g tank... Not anymore!

You know it's good when the only noise you hear is the water cascading over the top of the filter sock :lol:
 
I just upgraded a Velocity T4 to a Reeflo Snapper. I can hear the hum of the pump now (and the damn ocean runner needle wheel). Before the OR and the Snapper, you could HONESTLY not hear the tank even standing next to it. The T4s were nice pumps but did run a little hot and needed cleaned more than I liked.

The Snapper is a great pump, but I am not happy with the noise. It hums... it drives me nuts.

I've been avoiding this thread because I knew it would require in depth reading...

However, for your pump situation, did you put SpaFlex on the input and output yet? And keep in mind the pump will quiet down as it slimes over in the next few days. Aaron recently installed a Barracuda pump and had the same problem, but it has gotten better in about a week's time.
 
Thanks for dropping by Marc. I used spaflex on the intake and output and have also supported the pump on an isolation platform (rubber feet) on the tile floor, not attached to tank or stand. I have had it up and running for about a week. It is a bit better but still nowhere near "silent". The skimmer pump is louder so at this point I am ignoring it. Future plans are a melamine foam lined box with a fan :)
 
What would you recommend for the eheim pump in the sump... I have heard of people using mousepads, but I am a little weary to add one of them to my sump... Right now I am attempting to create a pad out of silicon in a carboard mold... Any suggestions?
 
McMaster.com part number 8608K12

It is 1/8" closed sell silicone foam rummber. 12" x 12" for about $12

Whatever you choose, choose a closed cell foam or silicone rubber with a somewhat soft texture. Many mousepads have the proper base material but also have glues and fabric and are not really suitable.

what about a piece off eggcrate under your pump, thats what i do and it doesnt vibrate at all, i have a mag 9.5

egg-crate? Really? I figured this would transfer vibration, not silence it... but I have a ton of it laying around maybe I'll give it a shot...

Sorry Bean, didn't mean to get off topic on your thread.

Also, Thanks for the link.
 
Thanks for the kind words!

I have been spending some time working on my touchscreen controller project, my dosing pump controller and a few other things. I am just finishing up the PCB design for the dosing pump unit. I will post them (and the silent overflow details) on my website soon.
 
I have a couple of ideas to run by you too, when you have the time. I have a distinct mental picture on how to build a proto-type for an automatic frozen food feeder that thaws, rinses, and dispenses frozen food.

Just no time right now to get cracking on it. Can't wait to see the doser.
 
I just got wind of it today...I haven't been paying much attention to RC lately as I am very busy with business and life in general. After a slew of bannishments and thread closures I got pretty down on the whole deal.
 
I have seen a tank running with 2 vs. 3 and it was indeed dead silent. I like the added assurance the 3rd pipe provides. After having a noisy tank in my TV room I'd like to achieve silence with the 150g that I'm currently working on. I have installed a calfo-style toothed overflow and the tank was already drilled for 2 - 1.5" bulkheads. I am planning on drilling a 1" bulkhead as the 2nd failsafe.

Are there any concerns w/ using 1.5" vs 1" bulkheads?

I noticed you went from 1" at the tank to 1.5" to the sump. Do I need to step up the pipe?

I'm not planning on running high flow the the sump aprox 1200gph before head loss.

Thanks in advance.
 
There should be no problem with the larger bulkheads. You do not need to step the pipe sizes for the proposed flow. Everything should run silent. I only had 1" bulkheads to work with and the 1" pipe is too restrictive for air AND water at the flow rates I am using.
 
Hey Bean...

I figured I'd post some pics of the build, and system in action for anyone who was interested.

Here's the plumbing...

Standpipes emptying into sump under the water's surface.

Cool shot of the calfo and standpipes in action... you can see the height of the water level in the calfo which I had to adjust via the true union valve on the syphon standpipe to dial it in.

And a shot of the front of the tank... you can see the calfo and the two standpipes which are submergered and the upturned emergency standpipe which remains above the water level.

I think the only differences are that I T'd off my syphon standpipe to feed the intake and fuge... The flow to the fuge is controlled by the ball valve.

Also I purchased my tank used, so the bulkheads were already drilled into the back of the tank... not at the straighest line as you can see.

As I stated earlier this works amazing and the only noise I get now after lowering my filter sock, is some vibration from the pump.

Once again... and I can't say it enough...

Thanks Bean!
