STS vs. Dirt w/BDBS Cap ?
I am starting a new 90 (48Lx18Wx25H) gallon planted rainbow fish tank and cant decide which type of substrate to get.
Safe T Absorbent vs Dirt w/ Black Diamond Blasting Sand Cap
Light: 48" BeamsWork DA FSPEC LED Pent -
In the future if i decide to go high tech, I may get a second FSPEC.
I want to start low tech (no co2). I will be adding liquid ferts (niloc g) along with root tabs.
My tap water has a pH of 8.2, gH 4, kH 2, and TDS of 180.
I know dirt is amazing for plant growth but its messy and eventually it loses its capabilities. With my high pH I feel i will exhaust my dirt quicker.
STS is "inert" with high CEC. The issues i'm reading is it strips the water of kH and drops your pH for the first few months. Not sure if this is a good thing for me since my pH is 8.2 but my kH is only 2.
ADA Aquasoil is nice but expensive and with my high pH, it wont last very long.
What route should I take?
Some plants I had in mind.
