Seachem Flourish Phosphorus 500ml
Phosphorus additive for planted aquariums. Phosphorus is one of the three essential elements that plants need. Flourish Phosphorus is a safe additive (4500 mg/L) of potassium phosphate that simplifies phosphate dosing. Since it is nitrate-free, it can be dosed according to the plants' needs without the risk of overdose. Flourish Phosphorus will enhance and accelerate plant growth without promoting algae growth. As shrimp and snails are often kept in planted aquariums, Flourish Phosphorus is safe for invertebrates. Ideal for heavily planted aquariums, such as Dutch-style tanks. 500 ml treats 37,500 liters.

A genuine product & you will be needing this for planted tank. It's at best price @ IndieFur.
adding to my reef due to zero phosphates causing nitrates to rise. Once I got the dosage figured out nitrates are dropping and I now get a phosphate reading on my hanna checker. Also corals all now have new growth tips so must be happy with some phosphate in the system.
