Hello I have an aqua clear HOB filter on my 10 gallon tank. It said for 5-20 gallon tanks on the box. I have the flow adjusted to the lowest setting. There's 3 male guppies in the tank that seem too have a hard time swimming around. I would upload a video but I can't seem to get it to work. I also have a small bubble wand in the back of the aquarium - don't know of that contributes to the current? Is there a way to fix this without getting a new filter? How can I tell if the current is actually to strong? The platy swims easily. Thanks for the help!
