Penguin filters are Marineland filters. Also, dont go by rating, go by gallons per hour.finnipper59 said:Penguin and Fluval usually make pretty good filters and so does Marineland. Even Whisper is a good brand to try. What would work best in a long tank is to get a size rated for a larger tank...rated for 30 or 40 gallons. Also, see if you can find a model that takes 3 layere of filtering media instead of just a single cartridge. They usually come with a sponge as one of their layers. This sponge can be cleaned by just squishing it in a container of dechlorinated water a few times and then you don't lose the beneficial bacteria in it.
Thanks for correcting me on Penguin and Marineland. I think I knew that, but overlooked it when trying to remember brands of filters. I've not shopped for filters in a long time. My canister filter for my 55 gallon tank is rated for tanks up to 150 gallons but I don't know its flow rate. Works great though. My bad.AquaticJ said:Penguin filters are Marineland filters.
