What kind of flow on colt coral

IME, I tried both direct and indirect flow. With direct flow, it didn't expand to it max but still did okay. When I did indirect flow, the colt expanded a bit bigger and extensions were longer.

I didn't notice any major difference besides that. HTH
 
mine did great under almost any current but the best was in a strong, indirect current where it would not blow it down..
