Seio Super Flow Pump M820

[arcanehacker]

Hi Hi.. I need some info on this Seio Super Flow Pump M820.

I've read aound and I think its flow rate is not controllable... am I right? Can anyone confirm?

If thats the case, then should I get this for my 4 x 2 x 2 tank?.. I'm afraid its too strong and might mess up the sand and all.. Will it? I intend to get 2 for both sides..

or should I get M620?

Thanks Thanks in advance...

for a 4 footer

i suggest u get a Seio M1100 instead

i am using 1x M1100 and find it two weak already

[hammy]

yup , i use seio 620 for my 2 feet

too weak? .. so it doesn't stir up really bad huh?.. Thanks.

Im using an 820 for my 3.3ft.....had comments from reefers that the flowrate isnt sufficient...think some reefers are even using the 820 for their 2ft. I find my flow alright, doesnt stir up my grade 0 sand at all.

It depends on the amt of water moverment u want and need in ur tank.

I have a 820 and a 620 for my 3ft but i am not satisified with their current.

Maybe a tunze can replace those 2.. and i believe the movement by tunze is better than seio too.. and lower wattage.

i am using a M820, the flow rate is actually controllable, but very troublesome, because the control is actually limiting the intake slots of the pump

not advanced like tunze, which can tune with the controller

yup. i am using an 820 in my 2x1x1.5 . i like the flow this way. though there is like still dead corners, but i guess that cant be helped, if i am not gonna install another seio into the tank...

anyway, i feel that for 3x2x2 tanks, a M1500 and a M1100 should suffice. maybe get 2 M1500... haha.. that is wat i am gonna do for my upcoming 3x2x2... i am a sucker for fast waters...

anyway my take is that you should get something faster... at least a 1100. bare minimum. no harm having fast waters... haha...

[arcanehacker]

yeah.. thanks.. Probably will get the 1100 and control the speed if its necessary.. But how about heat issue? I heard somewhere that seios generate heat as compared to Tunze.. then wouldn't 2 seio M1500 in a 3ft be a problem?

[jackryan]

Does it generate really that much heat ?

can. . why not use a tunze instead. tunze 6060 x1 is enuff.

i am using 6060 for my 2 feet cube. can cause sandstorm if u are using grade zero substrate
