As I mentioned in the other forum, I don't get your complaint as the intake strainer is not really any different than any I've seen. So what exactly is your complaint?The AquaClear is a great filter. I think the Fluval C series is more bell and whistle than cleaning. The only problem with the AquaClears are the horribly designed intake strainers.
Not if you got small fish, and shrimp.;-)The intake strainer on the AquaClears is way too small for the flow they have. I have seen apple snails sucked out of their shells when they reached the intake. I have seen healthy fish sucked to and pulled through the strainer. It is unbelievable that Hagen makes the AquaClears which have the worst intake strainers I have ever seen and Fluval canisters which have the best I have ever seen. They require prefilters IME and and Hagen doesn't have anything that fits them well. Prefilters are just an unnecessary additional piece of equipment to clean.
Well I have two running AC70 filters. One is a dedicated Seachem Matrix only bio-filter that uses a Fluval sponge pre-filter (which costs about a buck and fits over the inlet tube just fine). The other just uses the inlet tube outta the box and I've never seen a problem even with small fish, including neon tetras. Of course, it would be a problem with small fry, but so would almost any standard inlet strainer. I have to admit that both of my filters are set for minimum flow/maximum re-filtration and I'm sure that's a factor in this discussion.I said IME prefilters are needed with AquaClears.
