Καλησπέρα ,
Πήρα πρόσφατα τον PhosGuard της Seachem και ήρθε η ώρα να αλλάξω τον παλιό μου , οι οδηγίες λένε για δοσολογία , ένα καπάκι ανά 300Λ , εμένα μου φαίνεται ελάχιστη ποσότητα!
Μήπως εννοεί κάτι άλλο με τη φράση "one cup"?
Έχει χρησιμοποιήσει κάποιος αυτό το προϊόν?
Ακόμα κάτι που διάβασα για τους "λευκούς" αντί φώσφορους και ψιλό διστάζω να τον χρησιμοποιήσω είναι το παρακάτω άρθρο γραμμένο από την ίδια την Seachem.

Q: I've contacted Reef forums and I was told that your product releases aluminum, which will close corals for weeks and might even damage them! How can something like that not be stated on the package? Furthermore, the product description states: "PhosGuard is not an exchange resin, it will not release anything to the water". This to me is a bit of false advertising and puts reef tanks worth thousands of $ at a huge risk
A: In recent years, there has been speculation that aluminum oxide based phosphate removers like PhosGuard™ release aluminum into the water and subsequently damage corals. The evidence to support this claim was largely anecdotal.
So, through a series of controlled experiments in both freshwater and saltwater, we intended to address both the question of aluminum solubility and aluminum toxicity. The results of these experiments show that under reef conditions (pH near
there is no detectable soluble aluminum released from alumina. Under conditions of low pH and high dosage levels, soluble aluminum can be released from alumina; at three times the label dosage rate, we detected 0.2 mg/L aluminum at a pH of 5.3.
Additionally, aluminum oxide is not easily absorbed into the cell to cause negative reactions. Even at three times the dose of PhosGuard™, soft-bodied corals such as Sarcophyton remain unaffected.
