hey,
im havin some issues with sand in the water floating around.
its a a 4 ft tank with a hk 4 on each side. i hace on on the side and one on the other side in the back glass.
i cant stand the sand in the water like micro bubbles, i have played with them all day and nothing. can you point me in the right direction?

thats alot of flow for a 48" tank...i would recommend moving them lower on the glass and pointing them upward toward the surface and angled toward the middle of the front glass....

Yeah, I agree thats a lot of flow and better to move them down and aim them up.... are you using the really fine sand?....

no its not very fine.
i have found with very fine sand i have algae probs with it so i changes from tank to tank to this stuff..
im about to double check what hk they are i have 4 lol i only use 2 or 4 of them lol i have 3 number 4's and a 2 or 3? i dont remember but i trhink they are 4s.. one sec.

okay,
in the tank i have 3000 gph..

hk 4= ............1200 (2) gph
return pump = 600 gph
so i have roughly 3000 gph.
the fish swim around so they dont seem unhappy. my tomani tang loves the powerheads and plays in the flow all day.
i will lower them, and point them up. i played with them for a good like 40 min and i got it right now to a minimum of sand flying everywhere lol
should i just put them on the side glass and point the up or on the back glass?
thanks again
