Nah, looks pretty tidy to me. I don't know what mess you're talking about. (I have kids. Shaddup.)

I don't mind the bubbles. It's just reminiscent of .. an actual wave crashing. :lol: If you wanted to reduce the bubbles, have you tried drilling a small hole in the pipe just above the water surface so any air trapped in the pipe can escape out there as the pressure increases? It won't eliminate them altogether but can work to reduce them. The only thing with so many bubbles, methinks, is the salt creep potential.

Hmm. If you put an open riser somewhere on the surge outlet of the CSD before the surge reaches the tank, would that give the bubbles a chance to break? It would probably work best if it were just before the tank (on a horizontal length of pipe)... but I have no way to verify this, I don't have a pump lying around to test my theory.

There's actually a small hole just below the water level (if you look you can see some bubbles coming out of it) gets rid of the big "bloop" from the surge. Above the water line would act as a venturi (tried that) I'm good with the bubbles as is - i know many hate them, and yes salt creep is already a royal pain in the arse - but the surge motion is really neat in comparison to the more laminar flow patterns we're used to seeing in a tank...

Tony - you'll notice you never see shots of the rest of the basement :lol: the other 500 sq feet is the 6yr olds playroom... I'm contemplating buying a nice skidsteer so I can clear a path to the tanks :)

I could play - but I don't think a T'd riser would help out - in fact with the rush of the surge - I'd almost bet it would act as a venturi... If I really wanted - I could switch to the toilet bowl style surge system - eliminates the tail end bubbles of the syphon breaking; but I like the simple physics operation of this configuration.

Ahh, I hadn't thought of the venturi effect.

Bad Fish Tank! No donut!
 
Ok... So a quick 'tuning' got me in trouble tonight... :cry:

Drilled a new hole in the stockman, and 'waited, listened and watched' to see how it would change the system... Seemed like 10 minutes went by... Well that was 8 when I drilled the hole - I come back upstairs - it's 9:30 and the fiance is ****ed :lol:

Hmmm Maybe I should play a stop smoking hypnosis tape in the background or something when I stop to enjoy the tank :lol:

This weekends project - the new stand...

We'll see how it turns out... Going a little - um... Different (Yes it's me - y'all should expect that by now) :mrgreen:

Updated FTS later this week... Been a little hectic with the wedding and all - went extremely well, currently chilling in fairmont BC :)

AndyL 07-26-2009 05:51 PM

Well I'm dogging it as usual :) But Heading down for a topoff I suddenly realized - better get a shot up... Didn't get a chance to clean up or anything - but it keeps me in the contest :)

Added some locline to replace the big fugly 90 - 32$ (plus/minus change)

FTS due!! :biggrin:

AndyL 08-18-2009 04:08 AM

Gah! But I'm not ready yet!

Can I have a day or two to finish one or two things... And give it a cleaning? :D Wont get around to the fragging from the 10g that I was planning to do... But at least get me into the less ghetto range :mrgreen:

Yeah it's been a heck of a summer...
