Hello guys, Im in need of some help. I have a 45G setup. It is quite heavily planted. It contains 4 Otos, 6 blue rams, 1 Siamese Algae eater and around 45 Cherry Shrimp. After adding the last 3 Rams, my nitrate has spiked from 5ppm to around 10-15 ppm. Im thinking that Im over feeding them. So to bring them down I know the best way is to do water changes and not to add chemicals. I already do a weekly 30% water change. So my question is, to bring the nitrate back down to 5-10ppm, should I be doing water changes everyday? and when I do, do water changes, what % should I be aiming for?
