View detailsFrequently asked questions
Do I need to rinse UNS Controsoil before adding it to the aquarium?
No. UNS Controsoil is ready to use straight out of the bag and should never be rinsed, as rinsing will break down the granular structure and strip natural humic acids.
Does UNS Controsoil leach high levels of ammonia during startup?
No. Unlike traditional aquasoils that release massive initial ammonia surges, Controsoil is formulated with balanced organic nutrition, allowing safer cycling and earlier livestock introduction.
What is the purpose of UNS Controbase?
UNS Controbase is a high-porosity volcanic base layer enriched with long-term macronutrients and micronutrients that sits under Controsoil to prevent anaerobic compaction and stimulate vigorous root systems.
