 Re: Low PH and High Nitrates
Do your water changes to lower your nitrates but where do you get your water from? Depends on your water it may contain nitrates before adding or changing anything. For example i originally used water from my tap but not for long i tested the tap water from the sink it contained phosphates and nitrates. The nitrates in the drinking water was well over 100 ppm. Test it as fresh you may need to find another source. I myself use the seachem stuff i usually dont have a problem but if by chance it does drop i keep the seachem ph buffer on hand along with seachem reef builder it is an alkalinity adjuster. you want to shoot for a range of 9-12 dkh, maintain that range and your ph should fall in line. also big boost of calcium can alter both of these parameters so i would try the alkalanity adjust first. get good water and do regular water changes. i suggest smaller regular ones that will help maintain your parameters, lessen you bad alge, and IMO help keep your corraline. |
