Preis-Redu-Phos – 330 g

The increas­ing use of fer­til­izers in agri­cul­ture provokes a phos­phate con­cen­tra­tion in the tap water. On the other hand the remainder of food, the excreta, the phos­phate fer­til­izers for plants and the decay of organ­isms con­trib­ute also to a higher phos­phate level. If the latter exceeds 0,5mg/l the algae growth becomes quickly uncon­trol­lable. The brush algae, the beard algae and the blue algae (Cyanobac­teria) will pollute the fresh­wa­ter and the green fil­a­ment­ous (Spiro­gyra, sp.) and red smear algae will infest the seawater. Phos­phate is an ideal fer­til­izer for these algae. Some corals, espe­cially the hard corals, are very sens­it­ive to phos­phate and die when the water has an excess­ive phos­phate con­cen­tra­tion. PREIS-REDU-PHOS is guar­an­teed for its absorbency of phos­phate and its ability to retain it.
These special mineral gran­u­lates will not release any of the sub­stances which had been absorbed in the water, even when the product stops being active. By depriving the algae of their food, we reduce their growth. This can be con­sidered a big step in the battle against algae.
