The secret to algae control is quite simply, healthy plant mass- with an emphasis on healthy.
There are problems with dosing heavily in sparsely planted tanks. High macros/NO3 causes green dust algae easily in hardscape heavy tanks with light plant mass. This is why competition-aquascapers generally do not use the EI dosing approach in their tanks.
Our proprietary Capstone Ratio prioritises strong, healthy growth by consciously limiting nitrates (not to be confused with having insufficient nitrates), akin to providing slightly less carbohydrates in favour of more protein and vitamins.
This form of 'nitrate limitation' unlocks the deepest coloration in some of the most popular plants in the hobby: Rotala rotundifolia /colorata /H'ra; Rotala Goias, Hygrophila pinnatifida / araguaia; Ludwigia arcuata etc. It also helps to limit green dust algae, one of the most common and persistent forms of algae.
