can you find these at homedepot, i looked for a short time last time i was there, and didn't see any pop up sprinklers, maybe i just missed them,
here's a page that shows it plumbed
http://www.lunchbucket.org/Equipment.htm
do u think u could mount it the other way completely submerged and attach it to a powerhead in tank rather then a return pump, or would that mess something up with sprinkler

I probably read thru that link too quickly... but sure sounded like there is a TON of metal in those sprinkler heads... NOT a good thang around salt-water!!! I would be worried about what might leach into my tank with all those various metal springs and screws.

Hey Ed I am sure they removed all the metal parts incuding the springs before they installed it into the tank..

Yeah they went through step by step removing all the metal springs and screws from it and then plummed it as a closed loop with a mag 7.

i was more worried about it operating completely submerged, though i don't really understand how it works, i just thought about it u don't even plug it in right, so it should be fully submergable

Correct

Yep just a plastic rotating powerhead really, once you have it plummed with a pump. I like it I think I am gonna do it but instead of itsitting at the surface like his i am going to drop it its full length into the water andlet it do a 180 degree sweep of the tank from the back middle of my 90.

lol, so essentially it's like a tall one of these, where u can control the sweeping angle?

There is a screw on top that controls how much rotation the sprinkler does. I went to depot today and found this sprinkler head but in a different package. I also think that I will do mine with flexible clear tubing and nott hard PVC i find that its easier to go behind my tank with it. I do have one question though has anyone used a Mag pump externally and if so how do they perform, I.E. heat issues etc.

mine is not rotating, i've done the mod, i'll post pic later could it be that i don't have enough pressure, i'm running a maxi 1200 on it

 

[MarineTeng]

ok so i did the mod, i'll post pics tomorrow, though it doesn't work for me because my pump is not strong enough, it needs probably at least a mag 7 to actually make it spin, my maxi 1200 is not doing this, so if anyone's got an extra pump they'll sell for cheap...

 

[MarineTeng]

here they are, first here it is as i tried it with the maxi jet, doesn't rotate cause there is not enough pressure though

Here is the filter, i didn't use the pvc parts snailman did, i used a sch 40 male adapter 1/2" it only works with the filter in which is good cause the lunchbucket site says they clog in a couple weeks with out it, however the filter did have a part of plastic sticking out in the inside which i cut out with a wood carving knife and scissors, here it is put together (the adapter and filter)
