The device mentioned and pictured in the article
was demonstrated by Eric last year at a meeting
held at Aquatic Design.

Too bad I missed that meeting. I knew it was Eric's surge I never had seen a picture and in trying to read the article on it here on MARSH I was confused. I'd love to know how loud it is.

I too wish I hadn't missed that meeting. I would like to see how much salt spray results from the device. I'm used to noise, having multiple tanks, three kids and a parrot. It's silence that bothers me nowadays. :D

Although the unit he demonstrated was cobbled together for a
presentation at MACNA, it was relatively quiet (quieter than a
sump, quiter than the average overflow device and quieter than
a primary pump).

The exit pipe was longer as the unit was placed higher above
the tank and had a larger reservoir. ergo it delivered a
longer more powerful surge. Include an overflow in case the
flapper doesn't open.

Quite impressive. If you decide to build one use a 5 gallon paint
bucket instead of a pitcher (it holds more water and has more
room inside to work). Let me know, I would like to see the final
product.

Cakepro,

You must have posted while I was composing!

The surge pipe entered below the water line and
there was negligible disturbance at the top. A variable
height pipe with an ell at the end would control the
surface movement and the direction of the surge.

My tank backs up to my kitchen so I could drill a hole through the wall and put the surge tank in a cabinet. My biggest problem is that the tank is already set up and I need another hole for the closed loop. I could possible try the suck and blow closed system that was designed by melev.

This was my next project to remove the power heads.

I may still do this instead because it is so much easier.

Shouldn’t this thread be moved to DIY?

I have seen similar flapper surge devices and most include an overflow. This one uses the stand pipe that is connected to the flapper for this purpose. This is a clean implementation.. just as long as the water can be drained thru the stand faster than it is pumped in. Now I just need to understand the ‘S’ bend for the back pressure. I hope to build one eventually.

I'm going to see if I can build / test one of these on my euro-braced tank. Only thing I can see that I would need to change is the width of the neck "S". Any physicists out there who can tell me whether this will dramatically change the hydro dynamics of the thing?

Thanks!

Altering the length of any of these pieces will not dramatically affect the hydrodynamics of the system unless it were to lengthen any of them drastically (from a few inches to several feet for example). Also, adding bends can decrease flow significantly, whereas decreasing the number of bends can increase flow somewhat.

If you want faster drainage (an therefore increased surge) you can increase the heigth of the container above the tank by lengthening the final drop tube (20mm PVC pipe).

Why do you think they make pumps and other equipment so loud?? So you notice it when a pump stops from a dead sleep. :D

I'm not positive, but it seems to me that if the S bend was not there, water would start to flow out too quicly, creating a strong suction at the exit, which would suck the flapper shut. That's the only thing I can come up with by picturing it in action in my head.

surge

please forgive a newbie at saltwater but what would i use this for?
