Common questions about Monte Carlo
- Does Monte Carlo need CO2?
- Monte Carlo grows without CO2, but slower and less dense. Liquid carbon or injection makes the difference between a thin patch and a full carpet.
- What light does Monte Carlo need?
- Monte Carlo is a medium-light plant. Most modern aquarium LEDs cover this. Anything sold as planted-tank-ready works. The stock hood on a basic shop tank usually does not.
- Is Monte Carlo beginner-friendly?
- Monte Carlo is rated medium for difficulty. Plant small portions flat against the substrate, pinned if necessary, in fine nutrient-rich substrate. Trim occasionally to keep the carpet dense rather than tall. Compatible with most shrimp species.
- Is Monte Carlo safe for shrimp?
- Yes. Monte Carlo is safe in shrimp tanks. The usual quarantine still applies: any plant from a commercial nursery should be soaked and rinsed first to flush copper and pesticide residue.
