My Nitrate level dropped from between 20 & 40 ppm to zero WTF is going on all test levels were perfect. Done small water change with conditioned water 2 days ago and it was fine till today.....Anyone know whats going on in there?????
nitrate at zero is not a big deal...of course if you have live plants, the plants do feed off of the nitrate or/and phosphate, but you shouldn't be too concerned, for zero is an okay level...in time it will go back up
feshwater nitrate should be less than 20... less than 40 for sure.
saltwater should be lower, i do believe close to 0. saltwater tank inhabitants are more sensitive.. i dont have a reef tank,only keep brackish water for my mollie tank and spotted puffer tank. just keep it low.0-20
