Re: PMDD Dosing

Before I learnt this "1-ml-water-solution-trick" with the Chuck-calculator I
overdosed K2SO4, KNO3 and MgSO4.

Nice thread algaea the result was Yoda says.

(For those interested I put 2 tbsp of K2SO4, 2 tbsp of MgSo4 and 1 tbsp KNO3
in a 300 l tank after every 25% waterchange (it's okay to laugh ;). Now I do
the 50%-reset-ala-Tom-Barr with proper amounts with the help of the
calculator and the thread algaea is no more.)

My questions:

1) Does the "1 ml water solution"-calculator-trick really yield the right
2) Do I dose for 150 litres or 300 litres in my 300 litres-tank after the
Tom Barr-50%-weekly-waterchange-reset-method?
