I have a Marineland Portrait 5g AIO tank. As of now I do not have any corals in the tank but once I do they will be GSP, Pulsing Xenia, and a Kenya Tree. All the corals considered weeds lol, but I want the flowing corals for the tank. Since the start of the cycle I have had the return pump on as well as an old MP10w on the lowest constant speed setting. The clowns seem to handle it okay, they do hang within a few inches of the pump during the day and are 8-10" away at night. The peppermint shrimp only seems to come out when the pumps are off at feeding time. When the pumps turn back on you can see the clowns get sucked a few inches towards the powerhead but always catch themselves an inch or so away and dont get sucked in. My worry is the powerhead even on its lowest setting is too strong for them. I may just keep it off until I put corals in to see if its even needed for flow. If the stock pump (no idea on GPH) is too low I will see if I am able to get a different one in the back of the tank and not use a powerhead, BUT if I need one what do yall recommend for such a small tank that wont take up a ton of real estate?
