First let me comment on quantity.   I believe you should use a lot more TMG 
than the label says.   Some folks say 3-4 times the dose.  My rule of thumb 
is to work up to 1ml/gallon/week.  So my 50 gallon should use 50ml (or a 
bit less) per week.  I dose about 5-10ml daily.  I don't obsess over 
getting it PERFECT.
