For Dupla folks - Duplaplant tablet question
I use RO or DI water for water changes. My usual formula is to take the
water which is stored in 5 gallon jugs, and add the following - 1/4tsp
baking soda, 1/2 tsp RO Right (which I might bump down to 1/4tsp) and 1
Duplaplant tablet, crushed in a motar/pestle.
Last week I decided to use my iron test kit (LaMotte). I got a small shock
when it read .5ppm iron. I wondered how this could happen because a
previous measurement put me right at .1ppm. I thought I was using too much
Duplaplant drops (4-6 drops daily), but I had a hunch first.
I mixed up a 5 gallon jug of DI water, crushed up a tablet and mixed and let
the water sit for a while. I tested the iron last night - something like
.6ppm iron. Now, I bought the 50 count tube of tablets from Pet's
Warehouse. It says it treats 250 gallons. 250 gallons / 50 tablets =
5 gallons per tablet.
So, if the magic number is .1ppm iron, then what's the deal? Maybe the test
