Larger or heavily-planted tanks running an EI-style dosing routine go through phosphate fast, and a bigger bottle means fewer restocks mid-cycle. Dymax Phosphorus Plus 500ml is the larger size of Dymax's concentrated phosphate supplement, dosed directly into aquarium water to keep growth from stalling. Dose according to tank volume and plant mass, and pair with nitrogen and potassium dosing for balanced macronutrient levels. Best for: Larger planted tanks or multi-tank fertilization routines needing a standalone phosphate source. Size: 500ml | SKU: DM-PP737
