TwoTankAmin said:I am now up to 18 AquaClears (from Mini to 300) running on assorted tanks. I have yet to have one overflow. I also do weekly maint. that involves rinsing the media and replacing any floss. Most of them have a prefilter sponge over the intake.
I got my first Aquaclear (20) last month and love it so far. I too use a pre-filter on the intake, an Aquaclear 30 sponge. 2 sponges in the basket. It is a LOT quieter than the mini bio-wheel too, due to the wider and therefore smoother waterfall. I also like how the flow control works as opposed to the mini bio wheel.
