hey i got a 20g L tank and i have a penguin 350 gph filter - is that too much filtration ??? cause i notice sometimes these guppies get sucked onto the water sucking attachment thing.
try using a sponge on the intake tube; that would keep smaller fish from getting sucked into the filter . . . I don't believe a tank can be "over" filtered, I like as much filtration as I can get . . .
lol guppies getting sucked in. They must be tiny guppies. I say its fine I would not change anything. Unless ofcourse you want to trade your 350 for my penguin 200
I agree use a sponge to help them not get stuck. As far as too much filtration, I personally believe........ No such thing! Now I do believe you can clean your tank to much and kill the bacteria or leave nothing for the bacteria to "feed" on but you can never have too much filtration imo. but that's just my .02 cents.
