is there a cartridge of some sort out there that's used to help control phosphates that will fit in the spare chambers of my Emperor 400?if not, what's the best product out there that controls phosphates?
Use ROWAphos. It works excellent and can not reverse on you . That is when it is exausted, it will not release toxins of any kind. You run it 24/7 and when you phosphate levels rise, just replace it. It brought my phoshates from .5ppm to 0 in 24 hours and has kept them there for a month now.Check it out: http://www.deltecaquariumsolutions.com/rowa_1.php http://www.northcoastmarines.com./rowaphos.htm
