Hi all hope someone can help me my nitate is high in my tank but my tap water is also high what can i do to lower them many thanks
How to Reduce Nitrates
Unlike ammonia and nitrites, the bacteria that remove nitrates do not like oxygen rich environments. Therefore, conventional filters do not harbor the bacteria that remove nitrates. Although special filters exist that will remove nitrates, such devices are usually expensive compared to other filtration units. However, there are some steps you can take to keep nitrates low.
•Keep the tank clean – Waste ultimately produces nitrates. Cleaner tanks produce fewer nitrates in the first place.
•Don’t overfeed the fish – Overfeeding is a significant contributor to excess nitrates and other undesirable wastes, such as phosphates.
•Water changes – Performing regular water changes with water that has little or no nitrates will lower the overall nitrate level in the tank. RO/DI water is an excellent choice for keeping nitrate levels low.
•Keep live plants – Live plants utilize nitrates, and will help keep nitrates in check.
•Use nitrogen removing filter media – Instead of an expensive denitrator or special filter, use special media in the filter you have. Although they will not lower nitrates dramatically, if used together with other methods the net result will be beneficial.
If you use distilled or reverse osmosis water, use it for every other partial water change. That will reduce nitrates without eliminating the buffers needed to keep pH from going up and down. Just how high is the nitrate reading? As helinova explained, reasonable levels of nitrate are not harmful.
