Marineland Penguin Power Filter = Protein Skimmer???
I have a 30 gallon Salt Water Reef Tank w/fish. Its been cycled, and running perfect for about a month. ammonia, Nitrate, and Nitrite are fine. I have 2 Penguin Power Filters, one Penguin mini, and the other a 170, on opposite sides of the tank. I have been told that it is best to get a Protein Skimmer for all salt water tanks. My question is this: doesn't a Penguin Power Filter do the same job?
The manual says the Penguin Power Filter has a 3-stage filtration system:
1. Mechanical filtration: traps solid debris.
2. Chemical Filtration: uses activated carbon to absorb dissolved pollutants.
3. Biological Filtration: wet/dry bio wheel filter, adds oxygen and beneficial bacteria.
*also having the two filters makes good waves, and no dead spots where there is no water flow, or debris build-up.
That seems to me like the same description of a regular filter + protein skimmer!!! What do you think?
