Salifert have a liquid iron based phosphate eliminator They claim that the flocks will be skimmed out. They also say that it is difficult to measure a drop in the phosphate in the water column because the flocks - before they are catched by the skimmer - will release its phosphorous because of the low pH in the test.
My idea is to inject this product in my return siphon very, very slowly around 0.2 ml/minute. The siphon ends in the same apartment as my skimmer and the skimmer have the same flow as my return (nearly) It will have a contact time of around 2 minutes and will be mixed very well. This will be a type of flow through like it is in many waste water plants. I will use a GHL doser (the new FW let you set an own wanted flow/minute - lesser than the calibrated flow. A GHL magnetic stirrer that will be configured to stirr 2 sec every 30 sec during a dosing event. My turn around is around 15 minutes and the daily dose will be 3 * 5 ml. Late in evening, middle of the night and in the morning. With 0.2 ml/minute a dose event will take 25 minute - nearly two turnarounds.
Please post your experiences but I´m only interested of iron based liquid phosphate binders - not the ones that use lanthanum
