Brown Algea Problem

i have another tank the same size and saltwater with a 550 penquin power head and no problems on that tank
 
not enough flow, the aquaclear 30 is enough flow for a freshwater but not for saltwater. Get a high quality skimmer like bak pak or AquaC
 
ok i feed them pellets and flakes with garlic and sometime i feed them seaweed. so what size powerhead do i need
 
Both the aquaC and bak pak are around 150-200 american dollars
 
if i didnt have enough water movement wouldnt the pylos and zenia and the anenomes be suffering instead they are growing
