Aquaclear flow is bad, too much like a waterfall, not much horizontal water flow. It makes noise. Easy to clog with debris in the water, often requiring to play with it to start it up, sometimes complicated to restart. Old design which never changed since his release in the late seventies. It is beaten by the newer designs.
On the other hand, Aquaclear can be found used-cheap and replacement parts are easy to find. That is the only pro I find for this filter that i know since i was young. It was great by that time, it was one of the first HOBs, if not the first. However IMO Aquaclear is now obsolete.
I am running a Seachem Tidal 55 since 11 months and it is so superior. Silent, easy to prime, it primes itself. Flow is much better, more horizontal flow.
