Sili-Out 2 is an aluminium-based product with a purity level of 99 + %. Directions Please note the instructions on the product.

Key Features

Powerful silicate & phosphate control – high-purity aluminium oxide adsorbs problem substances within hours – combats diatoms & yellow tinge – ideal for marine, freshwater & nano tanks – no pH fluctuations.

Broad-spectrum contaminant removal – binds silicate, phosphate, arsenic, barium, chromium & more – protects from nutrient overload – perfect for reef, planted or high-load fish-only systems.

Safe & aquarium-friendly – 99% pure aluminium granules in fish-safe formulation – no pH impact, no metal leaching – suitable for delicate corals, shrimp, discus & breeding tanks.

Easy dosage & use – start with 50 ml per 100 l water (up to 100 ml for heavy loads) – replace once silicate or phosphate rises again – includes fine mesh filter bag – works in canisters, sumps & reactors.

Trusted ARKA quality – refined grain, low-dust & consistently effective – proven by breeders & reefkeepers – ideal in combination with myAQUA RO systems & Resin-Pure post-filters for top-tier water quality.
