i see this many many many times on the forum. Ok heres what i have to say. Bacteria lives on surface stuff, gravel, ornaments, tank glass and most of all the filter. It is not free swimming so when you change the water your not taking any bacteria out. Second to that, no matter how much water you take out, 1% or 99%, the fish will still poop no matter what so the bacteria will always have something to eat. Also no arobic bacteria eats nitrates (there is an anox bacteria that eats it though, but there used in saltwater) so the only way to remove a lot of nitrates at once is to remove a lot of water. 50% weekly is one of the best things you can do with the fish. I know someone who does 30% daily.
What are you talking about with the filter????? The more water that goes through the filter the more water that gets filtered so obviously a filter with a high flow rate is better. Where are you getting this information, i need to check that website out and complain to it.
