if u talked about the carbon filter media, then it was my fault talked about carbon dosing....
bro huma huma- yes....there are lots of successful reefer practising the carbon sources dosing in their salt water tank...im sorry if u didnt even heard that...n im not even talked about ammonia source, which i knew it will convert to nitrite then nitrates which bring your nitrate reading high...u need bacteria which will convert this extra nutrient to nitrogen...or else u need macroalgae which consume this as their food source to thrive in a tank...that is why, tank with high reading in nitrates and phosphates can give u problem with nuisane algae...btw, another commercial type of carbon source such NP biopellets, prodibio, etc which is run in a reactor...
