Shrimp only tank and fertilisation

[Navyblue]

The tank is 22G, less than a months old, and quite heavily planted. The tank is low tech, with little fertilisation. I envision the tank as an NPT.

I just introduced 17 adult RCS, with at least 3 newborns spotted (likely more hidden). The tank is fishless, so the bioload is extremely low.

At this point, I suppose the plants need to be constantly fertilised given the low bioload. But say the shrimp population reaches 100, would it be enough to support a tank full of plants? Can a shrimp only tank support the heavy planting without additional fertilisation?

Thank you.

depends on your substrate
but more than likely...CO2 will be your limiting factor...so low light + low CO2 = low nutrient demand...so if you have a nutritious substrate (like soil)...low light + low CO2 + high nutrients = slow balanced growth

also...are you sure that your tank cycled in under a month? shrimp wont survive the NH3 cycle

Substrate is Seachem Fluorite.

I plant heavy from day one, I never saw ammonia. It's either the plant or the bacterial film on the plant. Before I planted I also soaked the substrate in water and with squid in it for a few weeks.
