It's a 1/3 of the flow you lose, so I count my 2 per 125gal tank as 700gph not the 1000(500per) as manufacturer stated.




Very creative.I too would recommend Aquaclears if one is about to buy one or the other. But NOT due to the 'need' to be buying disposable cartridges for the Penguin because there is no need to buy new ones, ever, with just a little easy DIY (see below). With that aspect removed, the comparison is now fairer, now only in terms pf performance and characteristics.
In my opinion these two specific filters are complementary thus earning a role,i n different ways, in one's fish toolkit. I currently run 4 AC 110 and 2 Penguin 350, and, Fluval FX6, and 2 AC 50).
This is how I see them: Comparisons and roles. (Format - AquaClear/Fluval 500=110 --------------- Penguin 330, 330,b 350)
Total Volume (Water or media) - More. Less.
Turnover (gph)- More Less
Versality (media) - Complete Very versatile w/DIY (less volume)
Reliability (start/stop)- Excellent Excellent
Longevity (well cared for)- Forever Forever
Output delivery direction - straight down. More towards /across surface, less deep
Surface agitation/aireation. less (goes deep) Very high (+ additional agitation by biowheel)
Typical price $$ 75-90 34-45
My satisfaction factor - ++++ ++++
Pictures of DIY for Penguin, running on each side 1 modified cartridge (sponge), 1 tray of biomax noodles, and 1 biowheel. Once I bought trays for small noodles, and modified my first cartridges, I have never bought cartridges again, several years ago.
Cheers!
