<< At the SeaChem site (http://www.seachem.com/) in the FAQ about
"Freshwater Planted" there is an explanation of why the aluminum
oxide (PhosGuard) cannot be renewed as well as a discussion
about phosphate removers.
This discussion of phosphate removers seems to conflict with the information
given on the Kent Phosphate Sponge container. The Seachem website states that
the 2 phosphate removers are iron oxide and aluminum oxide. The Phosphate
Sponge jar states that other products will release soluble aluminum compounds
into the water, which their product does not, though it is white in color (as
the faq reports the aluminum oxide products are). I inferred that it is not
the same type of medium as the aluminum oxide . . . Unfortunately, Kent
Marine took an early holiday, and I couldn't reach anyone there today to get
more information on this, nor do they seem to have a web site. Forgive me for
being ignorant on this matter, but does a ceramic medium contain aluminum
oxide? I am a bit confused about the use of ceramic beads used in purifying
and deionization and the "ceramic" medium in the phosphate sponge. . . It
sounds suspiciously similar, and therefore would not be rechargeable. What
are the possible consequences of this use in the tank? (I mentioned earlier a
rise in pH and cloudiness)?
Happy holidays all . . .
