Advice on power-head placement please
 

Have 4 6055 Tunze power-heads as shown in photo. Tank is 5' wide X 24 X 24. Just trying to determine the best placement for these to create the optimum flow. Have set the 7095 controller to Interval 2 and the power at mid range. The 3 (high at the back) heads all aim toward the mid-center of the front of the tank and the 4th head is placed to along the back behind the rock (at left in the photo) and on full power.

Also, plan to add some sort of substrate soon. Is areganite (sp?) the way to go?

Many thanks:)

oh yeah...here is the pic
 

I have not been using "Night Mode".....is it a function that should be used?

You will get as many answers go this question as there are possibilities. My answer would be place them in a way that there are no dead spots as well as good flow everywhere (depending on what you will be keeping in the tank). I use night mode on my controller. It slows down the flow to allow the night critters to move about without being blown away.

Wow!!!!! Your tank is gorgeous!!!! :mrgreen:
