Am I going to find much differece between a 125 GPH filter and a 90GPH?

Question

The 90 GPH filtr is about 6 years old and seems not to suck much water do they lose their power over time?

Answer 1

The others are right, filters certainly lose power over time. Depending on the type you have it may or may not be correctable, but most likely not. Your current filter may be only opperating at 1/2 it's rated pwoer, in which case you would see a HUGE difference if you move up to a new 125 GPH filter.

Pumps do seem to slow down after a while. All of them tend to plug up after a while and get much slower than they are rated for.

I don't think you will see that much difference in those two pumps. I use a variety of pumps, and they always work at a much slower rate than they are supposed to(after a couple of days).

I always try to get a pump that is at least twice what I need. If you need a 125, look at a 250 gph to 300 gph. It will run a lot longer(and faster)without the constant maintenance.

If you are talking about the kind of filter that hangs on the back, go double what you need. If you have ten gallon aquarium, go for the 20 or 30 gallon filter. If you have a 20 gallon, look at the 30 to 55 gallon filters. You can't ever have too much filtration and those filters are WAY under-rated anyway.

Answer 3

All filters are run with motors and they do ware out. If you think yours is not pumping sufficiantly and you want to upgrade then I would go to a 125 but you will run into the same problem of the motor giving out in several years. You also might be able to replace the current motor if the filter is still made. Good Luck!
