power head placement

[bongo]

to continue the discussion on the other thread...

the 2 k4s are not place behind any rock... there out there

they are placed on each side of the tank and tilted and bit so that they produce a circular patern

the modded mj1200 are placed so that one of their two flow positions would contribute to the circular patern and the other patern create disturbance

[Vincenzo.]

go down a few threds to hookups, 'flow within a tank'. We discussed all sorts and types. And there are good links too

[Hookup]

I like what you have described for flow.  Mass water movement and some "chaotic" flow.  If you can get a timmer or three for some of your pumps, you'll get even more chaotic flow.  Turn a few pumps off for a few hours, then back on again  kind of idea.

[bongo]

yeah I got that covered!

the three modded mj1200 are on a wavemaker thus they turn on and off and the mod makes them go left or right

kind of reminds me of myself when I try to aquascape... this rock left... no right.. no left

[Vincenzo.]

how big is the tank?

[bongo]

90g with a gestimate of 3400 gph

sure the k4's are kinda in view but it's bettter than having my LR covered with... stuff

After reading Hook's thread and links, I was thinking of maybe changing the flow patern from circular to up and down in order to use the gravity

[Vincenzo.]

is that including gph from returns? Just calculate gph from power heads.

Personally id add more

[bongo]

oups...my mistake

it's more 4200 gph without the return
