I have a fairly big tank, (fits a huge goldfish, two koi's, two more average size fish, and some other small fish) The water is obviously some what cloudy because of all the waste. I was wondering if it is alright to add another filter to help reduce the cloudiness?
I dont want to spend a good 60 dollars on a new big filter, which is why i think a small 20 dollar one in addition to the one i have might be suitable.
Any help is appreciated. Thanks.
