Yes, you need water changes, but it is back to how you define cycling, and <"whether it is a valid concept">.Is it necessary or advisable to do water changes in a fully planted tank while cycling?
Yes, 2X 50% per week for the first 6-8 weeks is not unreasonable.So many conflicting 'arguments' on the net - and nothing conclusive - so I'll ask here (my trusted source): Is it necessary or advisable to do water changes in a fully planted tank while cycling?
