Pass on the Gh booster, you might do well to add some epsom salt, maybe 1 teaspoon, 1-2x a week.

Use Tropica master grow for your traces.

Greg will defintiely be coming out with a product that is similar to TMG but in a dry form and also has some of the same type of SeaChem Flourish traits as well.
But it'll be better than either because I am using some more expensive chelators for not just the iron, but all the metals.

It'll be about 10X cheaper than either name brand though.
1 lb will make about 50 liters and run about 50-60$.
I might sell it to the UK through a wholesaler(aquaessentials etc).

This June/July.

Till then, a 5 liter jug from Big Al's is the best/only place in the USA really, about 69.99.
