2HR Aquarist APT E - For Dutch or very heavy planted aquariums

Compared to conventional Estimative Index fertilisers: 2X more nitrate limiting for richer colours* 2X more magnesium for stronger growth^ Dose 2ml per 100L daily 1000ml lasts ~3mths for a 130 Gal / 500L tank. Pump not included *in terms of the relative amount of nitrogen vs other nutrients per ml. ^in terms of the amount of magnesium per ml. The EI approach pioneered by Tom Barr is designed to provide a unlimited / unconstrained amount of nutrients to plants based on a professionally Estimated Index of their needs. APTe provides a calibrated version for richer coloration and algae control.
