Sorry, I thought you were in the UK.

www.litemanu.com has all the chemicals you need and Big Al's sells the
SeaChem Flourish or you can use TMG(get the largest trace amount you
can). You can also try the cheaper DIY mix Plantex and the
litemanu.com trace mixes etc. I use these 1/2 the time to stretch out
the trace usage from the brand name stuff.

One order should last many years.
