Hey guys & girls. I need advice on what is best to do because I have a really annoying problem. I have sand as a substrate and my 4 ft spray bar to my fx5 still leaves big ridges because of the water flow. With all this, there is still loads of dirt laying on the top of the sand! I need help because I don't want to go to gravel because it harbors dirt etc.. My sand is about 3/4" deep, should I make it deeper? would this help?

Other people must have this problem because its forever bugging me, it did the same with a different sand in my old tank, but I never see big holes in anyone elses substrate.

So will adding more sand help? I could do with some power heads to move the water more, but it is impossible..

Thanks in advance.;)
 
Enlarge the holes on your spraybar. It will reduce the velocity of the jetstreams. I would also play with diffusing the return spray. Also riverrocks spread out over the sandbed will help break the flow going across it. More sand will just make deeper holes.
 
im assuming you have the spray bar with holes faceing down, so why dont you turn it around so the holes face up like i did with my xp2 and the water shooting up and hitting the surface disperses the force of the water causing no effect to the tank or you could drill more holes which would also disperse water pressure making it weaker....
 
No, i have it going tidrectly against the glass, so the holes are facing me ad i look in the wank. ill try facing them upwards. ;)

keep us updated, im sure facing the holes up will help and it also aids in oxygenation. how deep under the surface is the spray bar?
 
what I've done is got my first design of a spray bar which was just under 2 ft, i put this on the side of the tank at one end, and then the intake is pulling water towards the other end. I think this may have solved it because before the water was bouncing off the glass and getting forced downwared across the sand, but now it just flows all the way across the tank. Time will tell if it leaves any holes in the sand..
