Water changes in a planted tank
Been reading a lot before diving in, and seeing some conflicting ideas. In a low-tech nano (or bigger even, but light at 1-2 Watts per gallon, filter, heavily/densely planted, maybe some ferts/excel), are water changes required once the plants establish? Some peoplel post about 25% changes weekly or monthly (used to that from un-planted tanks), some say no water changes needed if you have a jungle of plants (low light, no co2)
What's the consensus?
