Aquadip Fosfo - Phosphorus

$3.59 ~~$4.99~~ In stock

Phosphorus (P) is one of the three essential NPK macronutrients for aquatic plants. Left over fish food and fish excrement normally take care of phosphate values in your tank. AQUADIP Fosfo is ideal for heavily planted aquariums with a high light intensity and with none to a few fish.

Add 10 ml per 500 liter to increase phospate by 0.1 mg/L.

It is recommended to check the phosphate values before and after dosing.

Recommended phosphate value in aquariums with a high light intensity and CO2 fertiliser is between 0.2-1.0 mg/L. Often combined with AQUADIP Nitro and AQUADIP Potassium.

Safe for fish, shrimps and crustaceans. Suitable for freshwater only.

My floaters were looking pale and the rotala wasn't growing at all, but after a few weeks with this phosphorus supplement I'm finally seeing new red leaves. The powder dissolves clear without clouding the tank.

My shrimp tank was struggling with stunted plant growth until I started using this phosphorus supplement—the plants perked up noticeably within a week. The fine powder mixes easily with tank water and doesn't cloud the glass like some other additives I've tried.

The powder dissolves perfectly clear in the water with no cloudiness at all. My java ferns have stopped yellowing and are showing new leaves after just a week of dosing this phosphorus supplement.
