Re:Red Sea Plant Care Kit
I'll try this again- Sorry about the blank message.-
Tom Brennan wrote asking for any suggestion from people using the Red
Sea Plant Care Kit.
I ran several tests on the iron part of the kit using test solutions
made from ferrous sulfate and from chelated iron solutions. I got
good agreement between my test solutions and the test kit(check the
April postings). I had no trouble seeing the difference between 0,
.1,.2 and .3 mg/L .
Some important points I found;
First you must view the test vial from the end and setting it in a
white cup facilitates viewing the color.
The color takes awhile to develop and you should wait the 10 minutes
suggested in the kit I waited 15min.
The light gray color at .2mg/L might be confused with the light blue
at no iron.
In any event, somewhere around .2mg/l it turns to a brown color and
you won't miss that.
Shortly after setting up a new tank and making only a few Flourish
additions I compared my tank water with the tap water I used to fill
it and I had no problem seeing that aquarium water had iron in it.
As for the CO2 part of the kit I didn't get satisfactory results from
it at all.
