130g tank and 2 streams 6100

[jon69]

I recently get 2 stream 6100 and a multicontroller 7094 for my 130 gallons tank. I actually place them one at each side front to front and an interval mode. The only problem, I have a 4-6 inch sugar size sand bed and I am not able to place them with good result. The poblem is that is always sand that move in the aquarium. what the best setup I can make for that the pump do not make sand movement in my aquarium. where I can place them in my aquarium (72 x 18 x 24) and how I configure the multicontroller 7094 for optimum result. Please give me clear information and if it possible a shema will be great.

I would aim them to blow across the aquarium side to side and be sure interval mode is working- the green light should be on. Keep the pumps clean of any sand, over time as the sand bed ages the problem will go away. In interval mode the pulses still work so just turn down the power of the pumps, to maybe 30%, 50% on each channel.
