SRC Member Otaku Reefer Posted July 9, 2019 SRC Member Share Posted July 9, 2019 Hi reefers, Anyone can advise on why my nitrates is low but phosphate high, currently no fish in DT cos running fallow, Fuge growing cheato and caulerpa nicely, is it possible macro need certain amount of nitrates for it to lower phosphate?? Currently trying rowaphos in filter bag, but seems no use, no space run reactor, any other methods of phosphate control? Nitrates : 0 phosphate: 0.4-0.5 Sent from Singapore Reef Club mobile app Quote Link to comment Share on other sites More sharing options...

I only know carbon dosing need the Redfield ratio.I will suggest to do a 20% to 30% WC and see. Quote Link to comment Share on other sites More sharing options...

In ur case if u want to go carbon dosing route, you have to dose nitrate as well. Quote Link to comment Share on other sites More sharing options...

SRC Member Otaku Reefer Posted July 12, 2019 Author SRC Member Share Posted July 12, 2019 quick update my phosphate drop from 0.469 to 0.144ppm, just after few days of half dosing nitrophos minus, but cant really conclude as i started dosing red sea abcd ard same time, means iron is dosed, so its either the nitrophos minus really effective or the dosed iron effect...anyway i stop both dosing both for now and will monitorSent from Singapore Reef Club mobile app Quote Link to comment Share on other sites More sharing options...
