When photosynthesis takes place, plants use the suns energy to combine carbon dioxide from the air with water from the soil to create glucose (a carbohydrate)....

For this reason, Wet/Dry, many HOB, and even many canister filters are not always the best choice for planted aquariums (especially for the "Walstad Method").
Wet/Dry, in particular, will strip CO2, as will many Hang-on-back (HOB) filters, and some canister filter set-ups (although a proper set of your canister filter products such as Matrix or Purigen along with LIMITED water spray in return can help).

My personal experience and knowledge of aquarium chemistry suggests that at least a simple sponge or more advanced fluid sand bed filter should be used for best results if you are using the "Walstad Method". HOWEVER, this depends upon your bio-load (fish, shrimp, etc.) versus the amount of plants you stock.
If you have more fish, for example, you will need more plants to balance them out.

In a heavily planted aquarium with a low bio-load, basic water circulation may be all you need if you are following this method. BUT, despite some commentary to the contrary, a tank WITH a high bio load (and this often includes large snail populations), a good bio filter is a MUST!

Many will ask, "What is the best aquarium filter?" Admittedly "best" is a loaded word, as there are many filters that will work. However, as you read further in this article, you will see that some filters can and will effect chemistry, water parameters, use of fertilizers, etc. more than others, and thus, have a positive or negative influence on your aquatic plants.

Based on my head-to-head controlled tests in the 1990s, I found that quality sponge filters and fluidized sand bed filters met the requirements for aerobic bio-filtration that best fit a planted aquarium environment. While other filters may work fine (for those of you questioning this who have other filters), the facts are that other filters will strip more CO2 from the water and will not provide the same levels of high aerobic bio filtration, nor respond to sudden ammonia spikes the way these two types of filters can.
This places them ahead of the others in the planted aquarium. It does not mean you can't use other filters, however. It just means our experiences and data show they have distinct advantages.

For photosynthesis to occur, plants need: · Light energy from the sun · Chlorophyll to absorb light energy · Carbon dioxide from the atmosphere and from respiration in plant cells · Water which is absorbed by the roots and transported to the leaves by the xylem tubes....
