Just curious with the houseing off should i put both pumps on each side of the tank and face them to each other???? i have 2 620

I've seen quite a few people do it that way. Won't hurt anything to try it.

Hi Steve,

It's a 48"x24"x24". I'll have about 2 to 3 inches of sand. I would like to keep clams and some various types of monties, shrooms and maybe an acro or 2.

I will be running a mak 4 for a return and then i was thinking a seio 820 and a couple of MJ 1200. The MJ's would be on a wave maker.

let me know what you think and thanks for the help.

regards

I hear u cant run SEIO Pumps on a wave maker

Hmmm.... Interesting.

Where did you hear this?

read it on the sites that sell the pumps.

Thanks. I didn't know this. :smile:

im trying to find out if j&l will bring one in for me. thanks for the pic gigy, that looks like the best way to mount them hey?

i think they cant be run on wavemakers because the constant on and off demagnetizes the impellors.

I can verify that they can't be run on a wave maker. I had 2 820's, and a MJ 1200 on a wave maker in a 75g tank. It made for really nice chaotic flow in the tank but the 820's lasted less than a month. There is a plastic tab on the impeller (inside somewhere). The constant on and off just chews up the tab and then the pump won't start. The plastic jams against the magnet and won't let the impeller rev up. If you take the pump apart and physically loosen the plastic from the magnet, the pump will start once and continue spining until power is removed. It then will not start until it is taken apart again. I am lucky. The store where I got the pumps is replacing the impellers under warranty. These pumps are great, but definitely not for use on a wave maker.

i called j&l, they said they wont bring any of the larger ones in untill they sell the smaller stock off :frown: might be awhile before i get one. maybe jack can hook me up.
