Where to place powerheads

[tone2607]

i have 2 korala 4's in my 75 on each end and keeps throwing a sand storm thet r pointed to the middle of the tank and on an angle up, anybody have a specific location that they dont get sandstorms everyday..?

Trial and error Tony. I've had my tank running for over a year and I'm still trying to get it right. If I look at the tank the wrong way I get a sand storm.

yes that is exactly whats happening everyday i come home from work i have a new bare spot on the bottom and sand everywhere, i think i have been doing more basting the rocks than anything

Maybe the #4's are too much flow. Not including your return flow, your at 32 gallons being overturned every hour.
I dunno. Its probably fine and just need to find the sweet spot.

Got a pic of the whole tank?

I have both my powerheads on the side. One faces the front glass slightly and the other faces the back glass slightly. There is some overlap in the middle of the tank where the flow is the strongest. They both face slightly upward as well.

Tone - that looks like a 90?

If so - in my 90, I have the Koralias up near the top of the tank pointing somewhat downward - it ends up providing good flow to most of the tank....

nope its a 75g ,do u point it downward towards the corners or just the front

I put them up within a few inches from the top with about a 5-10 degree down angle. Try it....

I have two Koralia 4s in my 90, resulting in some pretty heavy flow - so you might be a little too strong in a 75...

yeah i was thinking toward that way a little my self thats why i tookone out and put the old seio 1500 back in but iam also noticing dead spots in the sand (not alot of flow and causing it to turn brown a lil )
