water movement

[SHAKEEL]

i was wondering how do you most of you of r/c position your power heads for water movement in your tank it seems that im always redirecting mine.

Every time a change some rock around or add something I try to adjust, make things worse and end up adjusting it all back,,,,i should leave it alone but I just cant keep my hands out lol

I've always put powerheads at both ends of the tank. Always up top, aimed at each other. The middle of the tank is high flow. Corals that like alot of current go in the center, ones that don't go to the sides.

I use three koralias #4's. they have a very wide range of turbulant flow and with an lps dominant tank this is what I have had to do do satisfy all

One in the right back corner near the surface enough to really cause turbulance---you want this on the surface since this is where alot of gas exchange occurs

One on the left front corner--pointing down but also creating surface turbulance

These both are on a 3 minute interval timer,

One other koralia on the right side near the bottom of the tank. This is creating a flow upwards and also a draft across the substrate without a sand storm.

This gives me a circular flow from return side to bottom--across the bottom --back up to the surface --across the surface to the skimmer.

As cloak suggested --this also creates the highest zone in the tank as the most flow. This will allow me to place some sps corals near the halides some day.

with the returns and the k's I am averaging about 4400 gph

I like aiming some of mine toward the glass, to push off and give a disperse flow.

I agree but you really have to be careful of collateral damange still.
