Just a point, Fluorite can be messy, if you tried to add it to the tank with standing water, it will be a great big haze. Empty the tank completely, lay down the Fluorite then fill the tank very gently, pouring the water over a saucer.

Green Light Stump Remover
Grant's Stump Remover - this one is a bit more difficult to measure as it comes in pellet form rather than a fine powder.

First off, if you know a couple of others around you (try your local aquarium society) who are also looking, then you can just order from www.gregwatson.com
The only reason I suggest having a few other on board is because the shipping is pretty steep for just one person. I ordered with two others and even after shipping Greg was the cheapest source for all our fert. needs.
My only complaint, which has nothing to do with Greg or his operation, is that I don't like the CSM+B trace mix. I'll use it until I run out, but the trace mix I got locally was better. The CSM+B stuff gets mouldy unless refrigerated and contains less Iron then the local stuff.
Indeed (I did honour's research on chelates), but I wonder if a stronger chelate is a good thing or a bad thing. The chelates are there to keep the metal in reduced form, so a weak chelate might just mean that the element gets oxidized quickly, also requiring the plant to expend more energy to first reduce the element before use. Perhaps the ideal is somewhere in between?GregWatson said:Here's the catch with "trace" mixes ... some chelators are stronger than others forcing plants to expend a greater amount of energy to break the chelator bond with the element that the plants want to consume. Now I'm not the scientist type person, so I can't tell you much about the different chelators ... just that it is an issue ...
