My substrate is Tropica plant growth capped with Denerle micro gravel, there is a good 1-2cm of Tropica GS over the base of the tank, the minimum gravel depth is 9cm ramping to the back and corners to 15cm depth. Plant growth is not brilliant and I have been round all the other parameters, consistent EI dosing and CO2, flow, lighting levels etc so substrate is now my focus
My questions are....
Should the roots of the plants be in close proximity to the Tropica GS to gain good growth even with EI?
If i plant in the 15cm depth gravel is there any benefit from having the Tropica GS at all?
How can achieve a nutrient rich layer on the deep gravel areas, is it possible to rectify this without a total tank strip down!
