Hey guys I have upgraded my lighting and filter and now I need to know the best kind of wave maker or power head for my 20 high. Currently I have This as my power head and added filtration. I figured it couldn’t hurt to have more filter along with the water flow. I just don’t know if it’s moving enough water or not enough. I have green star polyp frag, torch frag, black star polyp frag, gold pot mushroom frag, and Zoa frag along with rock flower nem. How much gph should I be moving? Where should the water flow point. I’m sorry to be so needy I just want to ensure I’m doing the best I can and you guys are so knowledgeable.
