AquaClear 50 Powerhead, 270 Gallons per Hour, UL Listed

I used this to replace a Marineland Powerhead, my second powerhead to have failed in as many years. Since the powerhead is used to drive the undergravel filter, each time the Marineland Powerhead died, the biological balance in my tank went haywire- leading to green/blue algae blooms and stressed fish. I’ve just about had enough of it, and decided to buy the Aquaclear version.First, this product is labelled as “Made in Italy”. I’m not entirely sure that’s indicative of good quality (let’s say I’ve had some run-ins with Italian cars). However, the filter felt like a quality piece, with a proper tight venturi tube connection, bottom ‘funnel’ adapter, adjustment levers that slide nicely and suction cups that actually stick to the glass and refuse to come off.In its default, full power configuration, this pump is actually almost too strong for my 29L tank, to the point where it was at first picking up stuff from the undergravel filter and blowing it out. I tried using the yellow lever as I understand that was supposed to be a flow control valve- but either it’s not installed correctly or is meant to be used for “fine” adjustment, as it made some- not a huge amount of difference. I then used the green/red lever- this was described as a “switch” to go between forward and reverse flow, but slowly moving it also ‘macro adjusts’ flow- once I had a suitable flow rate, all was good. The adjustable bottom positioning is a nice feature since I don’t need to slightly bend the undergravel filter tube to reach it. I would also like to point out that the Venturi tube section actually works properly, with small adjustments leading to an incremental increase in bubbling rather than essentially being an on/off switch as on other pumps. As I said earlier as well, I elected to use the suction cup mount and they are similar to Eheim suction cups in that they seem to refuse to come off once you’ve stuck them against the glass; the “hang” mount is also very nice quality as it is height adjustable and comes with a knob to adjust hold against the glass.Overall, for the low price, I would definitely recommend this powerhead.
