inadequate-I had far more plants than I had realized! Tom Barr's latest
recommendations (the Estimative Index) are starting to make a lot of
sense.
What was that (the Estimative Index)?
Is this the one you are talking about
For a 20 gallon tanks I add 2-3x a week:
1/4 teaspoon KKNO3
2rice grain's worth of KH2PO4
5mls of Flourish
and once a week after the water change
1/4 teaspoon K2SO4
That is as simple as you are going to get.
Do 50% weekly water changes and keep the CO2 in the 20-30ppm range.
