Dosage instructions

Turn off/ remove carbon filtration, UV, skimmer and ozone. Dose 10ml for each 100l, preferably at night, or when the aquarium light is off. After 48 hours, turn on/ resume skimmer and all others. Skimmer overskimming is normal after treatment, reduce skimming and empty/ clean cup regularly.

Monitor oxygen levels during treatment. We suggest pointing a powerhead to the surface and/ or add an airstone to add surface agitation increasing gas exchange.
