[quote=Mike T;17797]David:
Just remember one thing about most bead filters,
they’re modified swimming pool filter and/or are designed around them…
that is pretty obvious, what is less obviuos

is the huge difference in price , i.e.
-
Advantage 10, 60 cm diameter
1795 $
-
Ultrabead 60, 61 cm diameter 1295 euro =
1848.5 $
-
Swimming pool filter 65 cm diameter, good quality 318 euro =
453.9 $
(1 euro =
1,4274 U.S $)
¿is it just because of the additional cost of the beads plus the blower?
I'm using static K1 for mechanic filtration followed by dynamic (aerated) K1 for biological. I'm happy with the results, but I agree that different systems may work allright

with adequate maintenance
