I agree aswell, I see sometimes, a taking to the extreme of the high flow mentality on a planted tank. As if it will prevent algae or be some end all to other problems.
Lets go even bigger though, at the ADA gallery they use two filters on a 6 x 4 x 2 tank 360 gallons. They use x2 ES-2400 I believe. Less than x3 turnover per hour. These tanks also have Roseline Sharks. All the plants are thriving. This isn't about blindly following the ADA style because Amano said so, like some tend to point out. They have proved the concept on a large scale and in numerous tanks.
