Decline of reliability of AquaClear 500 / Fluval 110

  • We are currently upgrading MFK. thanks! -neo
.....just saw your location.
 
Dallas ft worth metroplex area. I'm sure if I look I'll find one. If this in craps out on me I might just upgrad my return pump. I have a danner mag drive 7, pumping around 400 gph, I like to keep a lower flow rate for better biological filtration might beef up to a 9
 
So I remembered another thread and yup I found it. Are these both from the tank you added sand to about 6 weeks ago? Not saying it's the sand, but if it's the same tank, I thought that sand was super fine or something.

Yes the one that last 9 days was with fine sand the previous one was coarse sand/ gravel. Sand does not get in the filter, it's nowhere near the bottom and I use a pre filter
 
I get it. I was just brainstorming.

No clue on why you'd have problems with 2 other than bad luck. Obviously if they were losing them that fast, it would be well known, but it's always possible that one particular plant had a problem and you may have gotten 2 from the same plant.

At one of the plants I worked at, we had a sensor go out inside one of the extruders, and we didn't know the temperature in one area inside it was about 100 F lower than it was supposed to be. For several weeks, everything that came out looked good, but the defects began becoming obvious a few weeks later.

Mechanical things like this might take months to show up.

Sand does do a number on the HOB'S but the older AQ 500's are quality especially if you can find NOS.
I would suspect a fliter with or without sand would last 2 weeks. I saw very little sand in the housing the intake tube filter keeps most of it out

Could be bad luck, I bought both of them from the same PetSmart since they are 80 in-store price.
 
Especially if your running a prefilter like you mentioned, not likely to be getting too much sand in impeller shaft. I just meant potentially the wrong types of sand can damage impellers.

Wrong types such as? I think something smaller then pfs like salt size would probably be worst since it's big enough to catch and grind the impeller shaft and small enough to easily get in it
