Potassium chloride supplement for dosing marine aquariums to increase potassium levels to the desired level of 400ppm.

Disolve in a container in about .5-1lt RODI water until it disolves and then dose accordingly to reach desired levels.

Every 2gms of our potassium supplement will raise potassium levels by 10ppm per 100lt of water eg: 400 litre tank potassium level is 390; to raise to 400 you'd need 8gms of supplement.

Price is per 500gm
