Silphos 400g
TUNZE Silphos is an adsorbing granulate on an Iron (Fe) basis for fresh and salt water, which removes silicates and phosphates from the aquarium water. Silphos is highly effective, safe and binds silicate and phosphate to the granulate, decreasing undesirable growth of algae and preventing the development of mucous algae. Silphos has a very high bonding capacity and should be used very judiciously.
- Bonding capacity of 1000g of Tunze Silphos: 280g of phosphate (PO4) and 80g of silicate (SO2)
- Grain 4 to 6mm
Prior to use, check the concentration of phosphate! It is not advisable to use Silphos at excessively low phosphate concentrations (below 0,015 mg/l) !
Use and dosage
Use a maximum of 200g for 1000 litres of water at the beginning. After two weeks you may increase the quantity up to 400g for 500 litres of water. Do not rinse out the material for fast removal of nutrients. Rinse out the granulate prior to use for slow removal. The material has to very well perfused.
If the phosphate and silicate concentration increases again, replace TUNZE Silphos.
Silphos reacts very slowly and continuously, thus can be retained in the water circulation. It is ideal for permanent silicate and phosphate bonding.
Check the phosphate and silicate concentration in regular intervals.
A lack of nutrients may cause the corals to die!
Avoid an over dosage!
