Hey /an/ i am a new fish keeper and today was the day i filled my 20 gallon fish tank, i had purchase a kit but the ratings on the filter were somewhat negative so i purchased a separate filter that is rated for a 30-50 gallon tank, anyways my question was can filter outflow be too strong for fish??? PLEASE RESPOND. picture is my filter btw

Yes, use rubber tubing to downsize it or little fish will get sucked up.

I thought you said inflow. I'm not sure how to modify outflow.
>>21621 could you please be more descripitive

Most fish live in places with much stronger currents than that filter will produce.
Some fish that have been bred to have extremely long fins may not be able to live with it. Bettas and fancy goldfish are a couple types that might have problems with strong flow.
You can build a baffle in front of the filter to direct flow downwards if you want. Or stick plants or decorations in front of it to break up the flow.
in my experience HOB filters don't create that much current, so I'd probably just try it out and see if the fish are fine.

is it a tall or a long 20 gallon tank?

Unless you're keeping very small or retarded fish, it's fine. The outflow needs to be disruptive in order to aerate the water.
