Topic: SEIO Pumps

vortex is the down side, Try adding a small powerhead to blow current over the top of the seio to stop a vortex from forming
 
I did have a vortex problem the first time. Then I redid the mount by drilling the hole 3/4 inch lower than shown and now have no vortex problems.

You can fix the vortex problem by covering up the upper vent holes on the seio.

not a bad idea, It probably wont make much difference in flow with just two inlets covered. What did you use to cover them?

i never actually did it but i have seen tons of people on rc do it. I also saw them do it on the maxijet mod. I saw some of them glue like a really thin piece of acrylic to the top with super glue. If you can find the post on maxijet mods there are some ideas in there about it.

You don't need to cover them. If you set it up right.

you can't if want to run them near the surface. If you have seen any of the tunze they have the top vents blocked off so it doesn't cause that problem.
 
It works for me. In the link I posted before you will create a vortex. In that mount design the screw head to hold the pump mounting base is on the back side. You can get it lower. I left my camera at work but I will try and explain.

There are two parts to the mounting system as shown on the link.
Part one is the shaped like a hook that clamps on the top of the tank. Part two is the pump mount. The screw holds them together.

Put the two parts together just like you did in the link. Now looking at the backside (the side that will be against the tank) side the pump mount down until the existing screw hole is 1/2 from the bottom of the tank mounting bracket and mark the hole from the front side and drill a same size hole as the screw there. Now put them together screwing the screw from the front side.

You now have lowered the pump by 3/4 of an inch. It makes enough difference that the pump will not vortex.

I know this not the best description but if you look at the parts you will see what I mean or come over to my house and I will show you.
 
ya i know what you are saying. What i was saying is that if you want to run it right near the surface to stir up the surface water or something you can't without getting a vortex problem. That problem can be fixed by covering up the top holes on the intake.

nikonosis, while reefkeeps is chasing his fish around to do surgery I tried raising a seio and covering some of the intakes. It is not worth it. It can create a vortex from the sides. Better just to lower and be done with it. Then you can spend the free time going to the store for reefkeeps and get him some super glue remover.

HAHAHA, What the heck did he do? Im not worried about cause after running our old seio and with how expensive and massive tunze are, we are going to run a closed loop on the 180. Im not messing with power blocks anymore.
 
not a fan of the closed loop. Anyways mike that mod for the seio works great. I have not had a vortex problem. I have high surface flow so I think it prevents one from forming

why don't you like the closed loop? is it cause of the possibility of the bulkheads leaking?
 
that, takes up room, you have a huge pump when you can do the same job with a few lower watt tunze or seio's. If you are going inwall you cant have a room divider tank unless you close loop on the sides which is cool but alot of work. Its just something else that can go wrong when you are on vacation. but this is just IMO I have seen great tanks w/ closed loops
 
when we put our 180g inwall im def going closed loop. i don't want the look of the big powerblocks in the tank and i can run a closed loop off of 1 big pump instead of several tunze or seios.
