They look nice! And with a little sanding and paint they will look pro! Good job Willie :thumbsup: .
So these things are supposed to make your flow shoot out faster and at the same time smoothly? Can you explain a little in layman's terms for me Willie?

i gave a general description of the fluid dynamics involved in these on the previous page:

basically, the flowing water inside the pvc is at a lower pressure, so cutting input holes to the outside of the pvc causes a pressure differential between the inside & outside. this pressure differential causes the water outside to be forced inside, where the flowing water picks it up & shoots it out the end...free extra flow

just from holding my hand in front of the flow,they seen stronger,some of the mushrooms on the bottom seem to be moving more than before.....I don't know for sure but they seem to be working....I'm gonna paint 'em and use 'em like that,I like the look even if they're not
if I ever get the hammerhead plumbed in,I'm gonna try these 6 more times with bigger fittings :lol:

thanks,
James explained it better than I could,it didn't make sense to me either before he explained :lol:

I just tried something,I aimed the nozzles straight across the tank,I can see the flow across the surface....with the nozzles on there,the stream was going about half way across the tank and a wide pattern......without them,it was only flowing a third of the way maybe........so yep I think they work,I don't know if they are pulling in more water or if the reduced output is causing it to spray farther,but it is spraying out farther and seems to be a wide flow......I like it a real lot..... :lol:

yep I'm gonna try to dremel out the inside more and maybe take more off the back of the outside,I'd like the output nozzle to be flush with the back of the large section,that would open the holes up more,but I don't want to weaken the stand offs between the two.....
I already painted these 2 before I started thinking again,so I will make another nozzle and try cutting more out of it

Don't blow the epoxy off of the walls with that hammerhead
I added a ball valve if it's too strong,I don't want it to etch my glass either with these super high output nozzles :lol:

:lol: I didn't think about that. Those mushrooms are going to have to grow some hands so they can hold on to the rocks. :lol:
You can open that valve wide open and simulate ocean storms and hurricanes.
That pump is going to be great. Your new SPS corals that you will soon have will love the flow.

do you think I'll need the polario with the hammerhead,that would only be about 11000gph....12000gph with the little giant....about 40x turnover :lol:
