Good value but a big design flaw
on January 26, 2008
The XP3 is a very good canister filter.
The good? 3 decent sized trays, "priming" intake tube, configurable outflow tubes, all-you-need-in-a-box package (with exception of biomedia).
The bad? The quick disconnect is not heavy duty and can be distorted by any tension on one of the tubes (especially the output)--resulting in a leak because the O-rings do not seat. Also, the o-ring are not a "tight" fit and cannot handle much pressure. If you have any inline accessories that constitute a significant load (ie. uv sterilizers, CO2 reactors, etc), water will leak past the disconnect o-rings and onto your floor after flooding the top unit on the inside! Worst of all, this happens after about an hour or so and is not readily apparent!
Bottom line: I would much rather NOT have the convenience of the quick disconnect and instead have some external ball valves. My XP3 leaked on my the first time I used it. I searched online and this is a common problem.
