I've got a 46 bow with a cyano problem that I have determined to be caused by low flow. I've got two maxijet 1200s and another powering an aqua c remora. I've got a pile of live rock a little right of center with one powerhead positioned in the back left upper corner, pointing toward the front right bottom corner. The other powerhead is positioned on the back right upper corner, pointing to the back left bottom corner. The skimmer is positioned in the middle of the tank. I'm considering adding another powerhead but was looking for some adivce before I do so. Can I solve this issue with what I have and just reposition them, or does the third powerhead sound necessary? The locations of the powerheads are all from a point of reference looking at the tank. I appreciate any help and hope to get this kicked.
