PMDD Alternative/ Liquidoser
Here's an interesting product for the PMD formulators out there. There is a
product from hw Weigandt Gmbh called ferro vit. Its description is a
chelated Iron fertilizer for plants. It is availble from many of the mail
order houses in the US, and I have found it at a few aquarium shops in the
SF bay area. It cost $19.95 U.S for 1000ml, $6.95 for 250 ml mail order.
This compares to Duplaplant 24 from the same catalog for 39.95 for 100ml.
So about 20 times cheaper then the Dupla product. (miravit is their vitamin
trace element formulation) I sent for the analysis this is what I was
given:

Maybe someone can help me calculate how to mix this to create the
equivalent to Dupla drops and/or the equivalent to PMDD.?
Also is any one familiar with Eheim's liquidoser. It looks like their fish
feeder with a liquid proof rotating container. Does it work well?
Thanks Larry
