I ordered this item on Saturday and it arrived the following Monday. I am very satisfied with the delivery time. When I opened the product I found that it was smaller than I expected. All parts were included but the instructions were very vague. It wasn't hard to guess what went where. I tried to find it on youtube and was able to find a video but in a foreign language rofl. When I put it in the 46 gallon bow, I noticed that it wasn't very strong. I currently use Aquaclear110 and Marineland Penguin 200 for mechanical and biological filtration. Only two filters move a lot of water and agitate the surface. To be honest I couldn't even say the powerhead worked if it wasn't for the extra bubbles. I didn't want too much additional current, enough to lift debris off my sand surface and clear dead spots. I've tried different positions in my tank using suction cup mounts and placing the powerhead directly over my sandy bottom but I wasn't satisfied. Overall the product seemed decently made and would probably be more than enough in 30 gallons or less. I recently returned an item and will be taking the Hydor Koralia instead.
