Help me to choose new substrate.
I have 2 x 15gal tanks with Turface pro substrate. Lighting is 2x24W T5HO bulbs on each tank, pressure CO2 thru powerhead, Aquaclear 30 filter ,EI modified dosing, 50-60% water change every 10 days. Common med-high light stem plants. I have problem with plants grow and melting on some roots especially on toninas and [B]Pogostemon. I thing to get new substrate. One choice is to use The Miracle Gro Organic choice potting soil topped with existing Turface Pro. Other is to use Amazonia I.
Please help me to pick the right one. I’d like to grow nice plants with minimum substrate additives on other hand I’ll replant the tanks probably 3-4 times per year to try different scapes.
When more advanced substrate is in use do I have to lower ferts dosing in water column ?
