Re: Automatic Fertilization
To be quite honest, we do not normally recommend mixing these products together in the same container. The products are bottled separately because this is the safest and most effective way of using them. We do not recommend putting Flourish, Flourish Trace, and Iron in the same dosing system because they contain similar elements and there is the possibility of overdosing with Iron. This is why I say the second one is probably better. You are right about wanting to keep the phosphorus and iron in separate containers because of precipitation, but also do not want to risk overdosing Iron. Flourish Excel can go in the same container as Iron or Flourish Trace. The best way to dose these products is individually, but of course this decision is up to you.
