good ol' cyano Q's

[burrows14]

i have pretty decent flow . i have a tunze 6105 wavemaker and a korilia 3. im thinking of adding a korilia 4. I started off with a couple mj-1200's(came with the tank) and hated them. do you think if i moved my korila 3 to work the lower part of my tank would do the job or should i use the 4 to do that? also did you find you had a little sand storm going on?
