Ah... changing water every week will turn off many of us NPT ppl. Is this an ad you are posting? If not let me see some pictures of what you are proposing.
NPT means Naturally Planted Tank. It starts off with a soil layer under the gravel to nourish plant roots. The tank is then heavily planted so the plants can absorb (take in) harmful substances in the water, which are ultimately removed when the plants are pruned. Because of this natural filtration, water changes are few and far between.excuse my question.
What is NPT?
