Filter Help Needed ASAP

[aherbst]

Help please, which is the best filter between Whisper and Penguin? My freshwater tank won't clear up, I am using an Aqua Clear 300 right now, but it doesn't seem to work.
Thank you

What size is your tank? How long has the tank been up and running?
How stocked is it? When did you add them?

What are you using in the AC 300? Have you tried going with just 2 sponges and nothing else?

Maybe you need to goto the bigger aquaclear 500.

My AC'a do a great job. A1 filters.

What do you mean by your don't won't "clear" up? Are there actual particles floating around your tank? Large particles or small dust like particles? Did you distrub your substrate recently? How large is your tank? Is that AC300 the only filter on your tank?

I personally find that aquaclear filters are one of the best all around HOB filters. Stick two sponges in one, and you got an excellent mechcanical and biological filter (given time of course). In any case no matter kind of filter, you need to give the filter some time to filter out floating particles in your water. On my 66 gallon cichlid tank, I have a fluval 404 (to be replace with an Eheim that I'm eyeing), an AC200 and an AC300. Both AC filters have two sponges in them. One time, I rearrange the entire tank, and really stirred up some dust from the substrate. It took a couple of hours for everything to clear up... and this is on a tank that has a good amount of filtration on it.
