Penguins and AC's cost about the same, always swish the filter meadia in a pail of your tank water when ever it gets dirty, replace it if it becomes tathered or fuzzy looking, i swish ours about every 2 weeks or so.......
Ok so I just picked up a Penguin 100 (was going to get the 150 but I don't know that it will fit in the cut out on my tank hood).......... so my next question, whats the best way to switch filters over? I don't have room to have them both running on the same tank, so how do I switch without causing a mini cycle?
Try to put as much old media in the new filter as possible, you may have to cut it up a little and stuff it in the new filter, make sure to check your water at least once a day for about a week,,,What if the filter media is like brown...I take you have to replace then right?
Is the P-100 on the 10 or 20 gal.......![]()
That should be a good filter for a 10 gal, it's rated at 100 gph, a little less with media, .........I have a 10 gallon and just picked up a P-100 to go on there.
