Similar but definately not the same. Phosban is an iron oxide product while Phosguard is an aluminum oxide. The aluminum can and will affect the tank negatively, especially inverts.flanque said:
Phosphates and silicates yes but not really organics. What this does is export the one main fuel source that keep cyano going, phophates. This is a much better goal than what Chemi-clean does. Chemi clean reduces fixed nitrogens and oxidizes organics. It doesn't actually kill the cyano, merely coverts it's main food sources allowing the skimmer and the needed water changes afterwards to remove it. Chemi clean does not affect the phosphorus level much at all which is why more often than not the cyano returns. Think of it like a powdered version of O3 or peroxide.
