    Like the title says, are there any off the shelf nennie safe powerheads?

    I don't like the closed loop system so that's no option.

    I'm saving up to buy a decent set of wave makers but a nennie is definitely part of the future plan so I would like to benefit from buying the correct power heads now and not again later, if they exist...

    Thanks

    no

    Vortech is better, but not foolproof. I still gets floating pieces of Nori stuck to the sides and that is what will happen with Nennies.

    no, as not standard. You can modify the inlet parts to distribute or enlarge the inlet areas. So that there are less suction per slot or hole and the slots and holes are so that the anemone cannot cover most of them, thereby increasing the suction power. Or you can use sponges filters around the inlets.

    What you can also do is put a piece of glass in the corners at 45deg angle like in the pic and drill a hole in the centre more or less the same size as the pump nozzle that you wanna use. Put the pump at the back of the glass with the nozzle in the hole. Just make sure nothing can go over the glass, you can cover the top with egg crate, mesh or something. You can also put the glass a few mm from the bottom for water to go through. This way nothing can reach the suction side of the pump - nennie safe :)

    Forgot to mention, only downside is you won't be able to adjust the direction of the pump.

    A CLS is something to consider for a anemone system, it makes use of 1 inlet to feed the pump and the return flow can be multiple outlets (dependant on pump size)..

    alternitivley what tobes has illustrated is a good way to neni-proof a pump, another option to consider is a wavebox of somesort.. as the exit section of the pump is also the intake (water fills through the same cavity as the pump is switched on and off)
