spazz is very smart to have done the riser neck like that...it is much easier to adjust by reducing the riser diameter and making it higher...much less touchy. There are two types of foam rising action with skimmers. The wet skimming is when the bubbles rise in the neck by their own density and accumulation before they can pop. If a skimmer is collecting the foam at this stage, its a very wet and light skimmate. But as the bubbles rise in the chamber, then the dry skimming part comes in...where the amount of air passing up through the neck it what carries the foam up and into the collection cup. By lengthening and making this area narrower, there is a longer duration where bubbles can dry as they rise due to the updraft of air.
Making a wetneck on this is also harder than with a wider neck, but since the wet foam will rise quicker the neck wont get as dirty. I wonder...where did you get/ how did you make those reducing cones? I need. |

this is after 48 hrs of opperation. the first 24 hrs were breaking in peroid. so this is 1 days worth of skimmate. the cup is 10" diam. 6" tall. so in 5 days the cup would fill up and shut down the skimmer. |

Good luck on making the wetneck work on such a narrow neck...need a wider one for that. If this is a DIY deltec, you should be looking at making a SCH...self cleaning head anyways! Making the brush would be simple, you could fix it to a shaft, a motor and a timer from above to come on for a few minutes every few hours.

its a temporary stand thats comming down when i rebuild the tank. it will only be there for a month. its tied to the wall so it cant move around. i needed something quick and easy. its stronger than you would think being secured to the wall. i put my weight on it first to make sure it wouldnt move aound. the stand on mu 120 holding tank is tall enough to put the skimmer under the stand. hopefully i will be finished with the plumming real soon.

Hey Spazz,
Great work! Where do you get your OR pumps? What would you think the dims of a 6" skimmer with a single pump would have to be to work well? Thanks Steve

Awesome job dude! Looks better than Deltec or H&S. Do you really have to use needle wheel pumps for the skimmer to works?? The reason I am asking is because I heard that you can actually create the same effect of needle wheel pumps by sticking airline tubing (with or without DIY venturi pictured above) down to the intake pipe of the powerheads. Where do you stick the DIY venturi in your design, the intake of the pumps or the outlet??

Have you tested out the 4" pvc riser yet? to see if there was any better performance?

for a 6" skimmer to be efficent i would have it at least 30" tall main chamber with 2 2700 OR pumps. this should run a 75g tank with out any problems. or put 1 3700 OR pump in the place of the 2 2700's. i feel an 8" main body would do a better job skimming the same size tank. im a firm believer in building a skimmer for this tank and the next tank. that way you are not spending your hard earned money on a second skimmer you dont need. |

there are alot of pump makers working long hours trying to make pumps more efficent in there bubble production. even sequence is testing there dart with a needle wheel. |

HEY SPAZZ
VERY INTERESTING WORK......WOULD YOU LIKE TO BUILD ONE AND SHIP IT TO CANADA? I HAVE A 24" 16 DIAMETER TUBE THAT I NEED TO MAKE INTO ONE. YOU COULD MAKE THE PARTS AND I COULD JUST ASSEMBLE THEM. AND I COULD ORDER THE PUMPS....4 OF THEM COUSRE I WOULD NEED YOU VENTURIS....... LET ME KNOW AND WE CAN TALK FURTHER |
